Player Reports

  1. 1. Julio Rodriguez | OF
    Julio Rodriguez
    Born: Dec 29, 2000
    Bats: R Throws: R
    Ht.: 6'3" Wt.: 205
    Drafted/Signed: Dominican Republic, 2016.
    Signed By: Eddy Toledo/Tim Kissner.

    BA Grade: 75/Medium

    Track Record: Evaluators considered Rodriguez one of the best players in the 2017 international class when he signed with the Mariners for $1.75 million, but he has exceeded even the highest expectations. Rodriguez dominated the Dominican Summer League and both Class A levels in his first two seasons, earning hyperbolic praise from scouts, coaches and opponents. He suffered a hairline fracture in his left wrist diving for a ball in summer camp in 2020, but he returned with no ill effects in 2021. Rodriguez finished second in the minor leagues with a .347 batting average and seventh with a 1.001 OPS while climbing to Double-A, a performance even more impressive given the repeated interruptions to his season. He left twice to play for the Dominican Republic in Olympic qualifiers in Florida and Mexico and helped the Dominicans qualify for the Summer Games. At the Tokyo Olympics, Rodriguez hit .417 as the youngest player in the tournament to lead the Dominican Republic to the bronze medal, the first Olympic baseball medal in the country’s history.

    Scouting Report: Rodriguez is a physical presence at 6-foot-3, 210 pounds with the strength and athleticism to take over games. He destroys baseballs with 80-grade raw power and has been known to hit balls out of stadiums. His longest home runs come to his pull side, but he has the strength to drive balls out the other way with shocking ease. Rodriguez has the rare ability to get to his power without sacrificing the ability to hit for average. He is a career .331 hitter in the minors who identifies pitches well and stays short to the ball with a simple approach and direct bat path that allows him to make frequent contact in all parts of the strike zone. His swing occasionally gets too big, but he adjusts quickly within at-bats and doesn’t miss the same pitch twice. He is an adept two-strike hitter for a power hitter who stays on tough pitches and rarely strikes out. A plus-plus hitter with plus-plus game power, Rodriguez further enhances his game with his surprising speed. He is an above-average runner who is adept at reading pitchers and stealing bases, and he covers plenty of ground in all directions in right field. He is particularly advanced at ranging back on balls and keeps runners from taking extra bases with his plus, accurate arm. Rodriguez occasionally loses focus on defense, but he’s an above-average defender when he’s locked in. In addition to his physical skills, Rodriguez is an incredibly charismatic individual and a clubhouse leader. He has been bilingual since he was 18 years old and plays the game with a constant smile on his face, energizing his teammates and lighting up clubhouses with his outgoing, effervescent personality.

    The Future: Rodriguez’s talent and personality have him set to be not only the face of the Mariners franchise, but one of the faces of baseball. As long as he stays healthy, he projects to be a perennial all-star and MVP contender who competes for home run titles.

    Scouting Grades: Hitting: 70. Power: 70. Speed: 55. Fielding: 55. Arm: 60.

  2. 2. George Kirby | RHP
    George Kirby
    Born: Feb 4, 1998
    Bats: R Throws: R
    Ht.: 6'4" Wt.: 201
    Drafted/Signed: Elon, 2019 (1st round).
    Signed By: Ty Holub.
    Minors: 1-0 | 1.86 ERA | 13 SO | 1 BB | 10 IP

    BA Grade: 70/High

    Track Record: Kirby walked six batters in 14 starts his junior year at Elon and posted the best strikeout-to-walk ratio (16.8) in the country. Despite modest stuff, Kirby’s elite control and command convinced the Mariners to draft him 20th overall and give him a $3,242,900 signing bonus. Kirby remade his body in 2020 at the alternate training site and re-emerged with vastly improved stuff in 2021. He posted a 2.53 ERA in 15 starts and rose to Double-A, although he missed a month with shoulder tenderness.

    Scouting Report: Kirby’s fastball has jumped from 91-94 mph in college to 95-99 as a pro with explosive late life up in the zone. He generates his velocity with little effort and locates his fastball to both sides of the plate with plus-plus command, making it a swing-and-miss pitch even when batters are geared up for it. Kirby complements his fastball with a plus, wipeout slider in the 85-89 mph range that misses bats and an above-average, 79-80 mph curveball with depth and bite. His fading, 85-86 mph changeup has excellent separation from his fastball, but it plays down a tick because his control of it is just average. Despite his long, lanky build, Kirby is a good athlete with excellent body coordination and repeats his delivery for elite control. He has averaged 1.5 walks per nine innings in his minor league career and his misses are very small.

    The Future: Kirby’s rare mix of power and precision gives him the potential to be a No. 1 or 2 starter as long as he stays healthy. His major league debut should come in 2022.

    Scouting Grades: Fastball: 70. Slider: 60. Curveball: 55. Changeup: 50. Control: 80.

  3. 3. Noelvi Marte | SS
    Noelvi Marte
    Born: Oct 16, 2001
    Bats: R Throws: R
    Ht.: 6'1" Wt.: 187
    Drafted/Signed: Dominican Republic, 2018.
    Signed By: Eddy Toledo/Tim Kissner.
    Minors: .286/.429/.500 | 2 HR | 1 SB | 28 AB

    BA Grade: 60/High

    Track Record: Marte set himself apart with his athleticism, tools and performance as an amateur and signed with the Mariners for $1.55 million in 2018. He lived up to his pedigree with a standout debut in the Dominican Summer League and was invited to the Mariners alternate training site in 2020, where he understandably struggled as the youngest player in camp. Marte made his full-season debut in 2021 and finished among the league leaders in hits, runs, doubles, home runs, walks, RBIs and stolen bases at Low-A Modesto, earning a late promotion to High-A Everett.

    Scouting Report: A skinny, projectable teenager when he signed, Marte has grown into a broad-shouldered, physical specimen with explosive power. He generates borderline plus-plus power out of a smooth, easy swing and hits rockets that leave any part of the stadium. He uses his lower half well and has a mechanically sound swing that allows him to project as an above-average hitter who gets to his power in games. Marte occasionally gives away at-bats and gets out of his approach, but at his best he recognizes pitches, stays in the strike zone and adjusts quickly. Marte moves well for his size on the basepaths and is a good athlete at shortstop with twitchy actions, a quick first step and soft hands. He has above-average arm strength but is often careless with his footwork and arm slot, leading to frequent throwing errors.

    The Future: Marte has the potential to be a power-hitting, all-star shortstop if he cleans up his defense. Even if he moves to third base, he still projects to be a middle-of-the-order cornerstone.

    Scouting Grades: Hitting: 55. Power: 65. Speed: 50. Fielding: 50. Arm: 55.

  4. 4. Matt Brash | RHP
    Matt Brash
    Born: May 12, 1998
    Bats: R Throws: R
    Ht.: 6'1" Wt.: 170
    Signed By: Jake Koenig (Padres).

    BA Grade: 60/High

    Track Record: A native of Kingston, Ontario, Brash pitched three years in Niagara’s rotation and won the Metro Atlantic Athletic Conference’s pitcher of the year honors after he set the conference and school records for strikeouts in a single season in 2019. The Padres drafted him in the fourth round and signed him for $512,400, then traded him to the Mariners as the player to be named later for reliever Taylor Williams following the 2020 season. Brash broke out beyond all expectations in 2021. He finished ninth in the minors with 13.1 strikeouts per nine innings and rocketed from High-A to the majors, where he received a callup in the season’s final week but didn’t pitch.

    Scouting Report: Brash was limited by shoulder tenderness when the Mariners acquired him, but his stuff jumped exponentially with full health. His high-spin, 93-97 mph fastball collects swings and misses in bunches and his dastardly, mid-80s slider with power sweep and sharp dive is a plus-plus pitch that some observers grade an 80. He throws both pitches in any count and can finish batters with either of them. Brash complements his power offerings with an average knuckle curveball he lands for strikes and a changeup that flashes plus, although it is inconsistent. Brash has some effort to his delivery and his control can be scattered, leading to differing opinions whether he projects best as a starter or reliever. He holds his stuff deep into outings and improved his control as last season progressed.

    The Future: Brash’s stuff gives him a chance to be a frontline starter if he keeps improving his control. Otherwise, his fastball and slider give him closer potential in relief.

    Scouting Grades: Fastball: 70. Slider: 70. Curveball: 50. Changeup: 55. Control: 45.

  5. 5. Emerson Hancock | RHP
    Emerson Hancock
    Born: May 31, 1999
    Bats: R Throws: R
    Ht.: 6'4" Wt.: 213
    Drafted/Signed: Georgia, 2020 (1st round).
    Signed By: John Wiedenbauer.

    BA Grade: 55/Very High

    Track Record: A 38th-round pick by the D-backs out of high school, Hancock spent three years in Georgia’s starting rotation and posted a gaudy 1.99 ERA as a sophomore. He made only four starts his junior year before the coronavirus pandemic canceled the season, but the Mariners still drafted him sixth overall and signed him for $5.7 million. Hancock spent his first professional summer at the alternate training site before making his pro debut in 2021. He posted a 2.62 ERA and advanced to Double-A but was limited to 44.2 innings by recurring shoulder soreness.

    Scouting Report: Known for his advanced control and polished delivery in college, Hancock has become more of a power pitcher as a pro and traded some of that smoothness for increased velocity. He overpowers hitters with a 94-98 mph four-seam fastball that rides up and a 93-96 mph two-seam fastball that sinks down out of his low arm slot, with his two-seamer the better of the two pitches. His sweepy, 79-80 mph slider flashes above-average and his mid-80s changeup is a plus pitch at its best. Hancock’s delivery has become more effortful as he’s tried to throw harder and his control has regressed to average. He opens up early, costing him deception, and puts a lot of stress on his shoulder with his arm slot, raising concerns about future injuries. He had multiple starts pushed back last season in addition to two separate injured list stints for his shoulder.

    The Future: Hancock has mid-rotation stuff, but his delivery, control and health are all trending toward a bullpen future. He’ll try to reverse those trends in 2022.

    Scouting Grades: Fastball: 55. Slider: 55. Changeup: 60. Control: 50.

  6. 6. Harry Ford | C
    Harry Ford
    Born: Feb 21, 2003
    Bats: R Throws: R
    Ht.: 5'10" Wt.: 200
    Signed By: John Wiedenbauer.
    Minors: .250/.385/.344 | 1 HR | 2 SB | 32 AB

    BA Grade: 55/Extreme

    Track Record: Ford stood out for his premium athleticism at East Coast Pro and solidified his place as the top high school catcher in the 2021 draft class with a strong senior spring. The Mariners considered him one of the top three high school players in the class after he dazzled general manager Jerry Dipoto and other club executives during a private, pre-draft batting practice, and Seattle selected him 12th overall and signed him for $4,366,400 to forgo a Georgia Tech commitment. Ford made his pro debut in the Arizona Complex League and hit .291 with 10 extra-base hits in 19 games, including three homers in his final five games.

    Scouting Report: Ford isn’t particularly big at 5-foot-10, 200 pounds, but he packs plenty of bat speed and strength in his compact frame. He consistently squares balls up with his excellent hand-eye coordination and barrel awareness and drives the ball to all fields to project as an above-average hitter. He is a patient hitter who takes an opposite-field approach aimed at lining balls the other way, but he shows surprising plus raw power when he turns on balls. Ford is a plus runner, rare for a catcher, and has the athleticism to play multiple positions. His blocking and receiving need to improve, but his flexibility, strong hands and work ethic give him a chance to be an average defensive catcher in time. His above-average arm strength plays at any position.

    The Future: The Mariners will develop Ford as a catcher and believe he’ll stick there. Even if he doesn’t, his hitting ability and multi-positional versatility give him plenty of avenues to the majors.

    Scouting Grades: Hitting: 55. Power: 50. Speed: 60. Fielding: 50. Arm: 55.

  7. 7. Levi Stoudt | RHP
    Levi Stoudt
    Born: Dec 4, 1997
    Bats: R Throws: R
    Ht.: 6'1" Wt.: 195
    Drafted/Signed: Lehigh, 2019 (3rd round).
    Signed By: Patrick O’Grady.
    Minors: 1-1 | 2.45 ERA | 11 SO | 2 BB | 11 IP

    BA Grade: 50/High

    Track Record: Stoudt finished third in Lehigh history with a career 2.69 ERA and showed his stuff played against top competition with a solid summer in the Cape Cod League prior to his junior season. The Mariners drafted him in the third round in 2019 and signed him for $339,000. Stoudt had Tommy John surgery shortly after being drafted and didn’t make his pro debut until 2021, but he made up for lost time with a quick ascent. He went 7-3, 3.31 in 15 starts and averaged more than a strikeout per inning while rising from High-A to Double-A.

    Scouting Report: Stoudt got stronger during his rehab and came back throwing harder after surgery. His previously 91-95 mph fastball now ranges from 94-98 mph with good downhill plane. His best pitch is a split-changeup in the low 80s with late dive and run, and the added separation between his fastball and changeup has helped both pitches play up. Both are now consistently above-average pitches and flash plus at their best. Stoudt’s slurvy, mid-80s slider is an average pitch that flashes higher, and he has gotten better at separating it from his fringy, mid-70s curveball. Stoudt battled his control at times in his pro debut, but his simple, clean delivery and fluid arm action should yield average control as he moves farther away from surgery. He does have some effort in his delivery and needs to prove his durability after pitching only 81.2 innings last season.

    The Future: Stoudt projects to be a solid, consistent No. 4 starter who isn’t flashy but gets the job done. He’ll start at Triple-A Tacoma in 2022.

    Scouting Grades: Fastball: 55. Slider: 50. Curveball: 45. Changeup: 55. Control: 50.

  8. 8. Adam Macko | LHP
    Adam Macko
    Born: Dec 30, 2000
    Bats: L Throws: L
    Ht.: 6'0" Wt.: 170
    Drafted/Signed: HS--Vauxhall, Alberta, 2019 (7th round).
    Signed By: Les McTavish/Alex Ross.
    Minors: 0-0 | 3.60 ERA | 19 SO | 3 BB | 10 IP

    BA Grade: 55/Extreme

    Track Record: Born in Slovakia, Macko was introduced to baseball in the first grade when he began hitting balls off a tee at his elementary school. When he was 10, he began watching YouTube videos of Justin Verlander and David Price to teach himself how to pitch. Macko’s family moved to Ireland when he was 11 and eventually settled in Canada, where he grew into the country’s top high school pitching prospect. The Mariners drafted him in the seventh round in 2019 and signed him for $250,000 to forgo a Purdue commitment. Macko made his full-season debut with Low-A Modesto in 2021 and was limited to 33.1 innings by recurring shoulder tenderness, but he showed electric stuff when healthy.

    Scouting Report: Macko has progressed rapidly given his unconventional background. After sitting in the upper 80s in high school, he now averages 93-94 mph and touches 97-98 with his fastball. His primary weapon is a sweeping, high-spin curveball in the low 70s with late tilt and bite that gets both swings and misses and called strikes on both sides of the plate. He has advanced feel to alter the shape and length of his curveball, making it a consensus plus-plus offering. Macko also has an average low-80s slider and fringy low-80s changeup, although he mostly just dominates with his fastball and curveball. Macko flashes average control but struggles with consistency. He often cruises for a few innings before suddenly unraveling.

    The Future: Macko is frequently requested by other teams in trade discussions. His stuff and projection give him mid-rotation potential if he can stay healthy and tighten his control with more experience.

    Scouting Grades: Fastball: 55. Slider: 50. Curveball: 70. Changeup: 45. Control: 45.

  9. 9. Gabriel Gonzalez | OF
    Gabriel Gonzalez
    Born: Jan 4, 2004
    Bats: R Throws: R
    Ht.: 5'10" Wt.: 180
    Signed By: Luis Martinez.

    BA Grade: 55/Extreme

    Track Record: The Mariners considered Gonzalez one of the top players in the 2020-21 international class and signed him for a $1.3 million bonus out of Venezuela. Gonzalez immediately stood out after signing and carried it over into his official pro debut. He hit .287/.371/.582 and led the Dominican Summer League with 26 extra-base hits, earning reviews as arguably the top player in the league.

    Scouting Report: Gonzalez is only 5-foot-11, but he has a strong, physical frame and surprisingly twitchy athleticism for his muscular build. He rotates quickly with a lot of torque in his swing to generate plus power to all fields. Gonzalez is a power hitter first, but he has a good feel for contact and projects to be an average hitter. He covers the entire plate and has an advanced sense for hunting pitches he can drive. Gonzalez is a slightly above-average runner and has the hands and instincts to play center field. He presently has enough range for the position, but he may move to right field if he loses a step. He has the above-average arm strength to stick in right field if needed.

    The Future: Gonzalez is set to make his stateside debut in the Arizona Complex League in 2022 and will play all season as an 18-year-old.

    Scouting Grades: Hitting: 50. Power: 60. Speed: 50. Fielding: 50. Arm: 55.

  10. 10. Andres Munoz | RHP
    Andres Munoz
    Born: Jan 16, 1999
    Bats: R Throws: R
    Ht.: 6'2" Wt.: 243
    Drafted/Signed: Mexico, 2015.
    Signed By: Trevor Schumm (Padres).

    Track Record: The Padres purchased Munoz’s rights for $700,000 from the Mexican League in 2015 and watched as he blossomed into one of the hardest-throwing pitchers in baseball. He touched 102 mph by the time he was 19 and reached the majors at 20 before succumbing to Tommy John surgery early in 2020. The Mariners acquired Munoz in the trade for catcher Austin Nola, and Munoz returned to make his Mariners debut on the final day of the 2021 season.
    Scouting Report: Munoz returned from injury with his stuff intact. His fastball sits 99-100 mph and touches 102 with explosive riding life at the top of the zone and late armside movement in the lower quadrants. It’s a true 80-grade fastball he dominates with and throws more than two thirds of the time. Munoz’s tight, 81-83 mph slider flashes above-average when he locates it, but it is often a ball out of his hand. He has below-average control overall and is prone to spinning out of his delivery. Munoz still has to prove he’s durable enough to last a full season. He has topped 30 innings only once in six years.
    The Future: Munoz is ready to move into a setup role for the Mariners in 2022. He could be a closer if he stays healthy.
    Scouting Grades: Fastball: 80. Slider: 55. Control: 40

  11. 11. Zach DeLoach | OF
    Zach DeLoach
    Born: Aug 8, 1998
    Bats: L Throws: R
    Ht.: 6'1" Wt.: 205
    Drafted/Signed: Texas A&M, 2020 (2nd round).
    Signed By: Derek Miller.
    Minors: .407/.484/.593 | 1 HR | 1 SB | 27 AB

    Track Record: DeLoach scuffled his first two seasons at Texas A&M before breaking out in the Cape Cod League prior to his junior year. He carried his success into the following spring and was off to a hot start before the coronavirus pandemic canceled the 2020 college season.
    Scouting Report: The Mariners drafted him in the second round and signed him for $1,729,800. DeLoach continued his upward trend in his pro debut, rising to Double-A and finishing in the top five in the Mariners’ organization in hits, runs, doubles, walks and total bases.
    Scouting Report: DeLoach has elite pitch recognition and is rarely fooled. He identifies pitches early, stays in the strike zone and drives the ball with a simple, direct lefthanded swing. He hits both righthanders and lefthanders and projects to be an above-average hitter who draws lots of walks. DeLoach doesn’t pack much power, but he has improved at getting the ball in the air and has a chance to reach 14-18 home runs at his peak. He is just a fair athlete and needs to improve his range and reads in the outfield to become an average defender. His average speed and below-average arm strength profile best in left field.
    The Future: DeLoach’s ability to get on base gives him a chance to be an everyday player similar to Seth Smith. He’ll see Triple-A Tacoma in 2022.

  12. 12. Lazaro Montes | OF
    Lazaro Montes
    Born: Oct 22, 2004
    Bats: L Throws: R
    Ht.: 6'4" Wt.: 210

    Track Record: Montes is built in the mold of fellow Cuban slugger Yordan Alvarez, a physically imposing masher with huge raw power. He became Seattle’s top signing from their 2021-22 international class when the signing period opened in Jan. 2022, landing a $2.5 million bonus.
    Scouting Report: Montes can launch towering shots thanks to his plus-plus raw power from the left side. While power is Montes’ standout tool, unlike other players his age who have big power in batting practice but struggle against live pitching, Montes separated himself with his hitting ability in games. For someone his age and size, Montes has a relatively compact swing with good path through the hitting zone and the leverage to drive the ball for impact in games, giving him a chance to be a 30-plus home run threat. Montes’ offensive ability will drive his value, as he’s a below-average runner at best who will likely slow down. He’s going to develop as a corner outfielder, though he’s so big that there’s some risk he ends up at first base eventually.
    The Future: Montes is still years away from the big leagues, but if everything clicks he has the upside to be an impact hitter in the middle of a lineup. The 2022 Dominican Summer League should be his first step in pro ball.

  13. 13. Alberto Rodriguez | OF
    Alberto Rodriguez
    Born: Oct 6, 2000
    Bats: L Throws: L
    Ht.: 5'11" Wt.: 180
    Drafted/Signed: Dominican Republic, 2017.
    Signed By: Sandy Rosario/Lorenzo Perez/Luciano del Rosario (Blue Jays).
    Minors: .276/.364/.345 | 0 HR | 0 SB | 29 AB

    Track Record: The Blue Jays signed Rodriguez for $500,000 during the 2017 international signing period and traded him to the Mariners for Taijuan Walker at the 2020 deadline. After falling out of shape during the coronavirus shutdown, Rodriguez cleaned up his body during spring training and took off in his first year in the Mariners system. He shook off a slow start at Low-A Modesto to hit .289/.379/.470 with 31 doubles, 10 home runs and 15 stolen bases while advancing to High-A Everett.
    Scouting Report: Rodriguez has exceptional strike-zone recognition and solid bat-to-ball skills from the left side. He was previously too passive, but he started taking a more aggressive approach last summer and began driving balls to all fields. He lays off close pitches, rarely swings and misses and posts high exit velocities to project as an above-average hitter. Rodriguez mostly drives balls from gap to gap, but he does have latent raw power that could translate into 15-20 home runs as he matures. He is an average runner who covers plenty of ground in right field, although his reads and approach on ground balls could use polish. He has an accurate, above-average arm.
    The Future: The Mariners added Rodriguez to the 40-man roster after the season and view him as a potential everyday right fielder. He will begin 2022 at High-A Everett.

  14. 14. Edwin Arroyo | SS
    Edwin Arroyo
    Born: Aug 25, 2003
    Bats: B Throws: B
    Ht.: 6'0" Wt.: 175
    Signed By: Rob Mummau.
    Minors: .212/.316/.303 | 0 HR | 2 SB | 33 AB

    Track Record: Arroyo was Puerto Rico’s top player in the 2021 draft class and raised his stock with an impressive showing at the Perfect Game All-America Classic. He transferred to Central Pointe Christian Academy in Kissimmee, Fla. for his senior year and performed well enough for the Mariners to draft him in the second round and sign him for $1.65 million. Arroyo became famous on social media in his pro debut for his enormous bat flips in the Arizona Complex League, but he hit just .211 with four extra-base hits in 21 games.
    Scouting Report: Arroyo is a rare athlete who is both a switch-hitter and switch-thrower. That athleticism translates to his defense at shortstop, where his fluid actions, quick reads, reliable hands and plus arm strength give him the potential to be a plus-plus defender. He has advanced defensive instincts for his age and gets the ball out of his glove remarkably quickly. Arroyo faces more questions offensively. He has solid hand-eye coordination and surprising power, especially from the left side, but his swing frequently gets too big and doesn’t stay in the zone very long. He plays with a lot of flash and flair but at times crosses the line into empty showboating.
    The Future: Arroyo’s defense will buy him time to figure out his bat. He’ll see Low-A Modesto in 2022.

  15. 15. Milkar Perez | 3B
    Milkar Perez
    Born: Oct 16, 2001
    Bats: B Throws: R
    Ht.: 5'11" Wt.: 175
    Drafted/Signed: Nicaragua, 2018.
    Signed By: Tom Shafer.
    Minors: .185/.312/.222 | 0 HR | 0 SB | 27 AB

    Track Record: Perez starred for Nicaragua’s junior national teams as an amateur and made the all-tournament team at the 2018 COPABE 18U Pan American Championships in Panama. The Mariners signed him for $175,000 just before the tournament, the highest bonus given to a Nicaraguan position player in the class. Perez made his U.S. debut in 2021 and excelled against the increased level of competition. He batted .310 with more walks (39) than strikeouts (38) in the Arizona Complex League and received a late promotion to Low-A Modesto.
    Scouting Report: Perez is a patient hitter with uncanny pitch recognition for his age. He quickly separates balls from strikes, stays in the strike zone and makes solid contact on hittable pitches to project as an average hitter. Perez has above-average raw power, but his setup and approach are more geared for contact. He is a passive hitter content to draw walks and has a closed-off stance aimed at hitting low liners up the middle and the opposite way. Perez is a big-bodied third baseman who will have to watch his conditioning to avoid a move to first base. His plus-plus arm strength is an asset at the hot corner.
    The Future: Perez can be an everyday player if he makes adjustments to access his power, but that’s a big “if.” He’ll return to Modesto to start 2022.

  16. 16. Juan Then | RHP
    Juan Then
    Born: Feb 7, 2000
    Bats: R Throws: R
    Ht.: 6'0" Wt.: 178
    Drafted/Signed: Dominican Republic, 2016.
    Signed By: Eddy Toledo.

    Track Record: Then signed with the Mariners for $77,000 when he was 16 and quickly emerged as one of the top young prospects in their system. The Mariners traded him to the Yankees in 2017 in a deal for reliever Nick Rumbelow, only to re-acquire him two years later in exchange for Edwin Encarnacion. Then returned from the coronavirus shutdown with a star turn at instructional league, but he struggled at High-A Everett when minor league play resumed in 2021. He went 2-5, 6.46 in 14 starts and was limited to 54.1 innings by shoulder tenderness.
    Scouting Report: Then has plenty of stuff, but the results haven’t followed. His lively fastball sits 94-97 mph, touches 99 and plays in the strike zone. His slider is an above-average pitch that is his best secondary at times, and at others his above-average changeup is the better pitch. Then’s biggest issue is consistency. He has a hook in the back of his delivery that affects his ability to get to his breaking ball and his below-average control prevents him from effectively navigating a lineup multiple times.
    The Future: Then’s pure stuff excites evaluators who think he will be more effective in short stints out of the bullpen. He may make that switch to relief as soon as 2022 at Double-A Arkansas.

  17. 17. Michael Morales | RHP
    Michael Morales
    Born: Aug 13, 2002
    Bats: R Throws: R
    Ht.: 6'2" Wt.: 205
    Signed By: Dave Pepe.
    Minors: 1-0 | 5.79 ERA | 14 SO | 3 BB | 10 IP

    Track Record: Morales stood out for his polished delivery on the summer showcase circuit and followed with a 0.77 ERA for East Pennsboro High his senior spring. The Mariners drafted him in the third round and signed him for an above-slot $1.5 million bonus to forgo a Vanderbilt commitment. He made only one appearance after signing due to an unspecified elbow injury.
    Scouting Report: Morales is a prototypical projectable teenaged righthander. He is a good athlete in his 6-foot-2 frame and has a smooth, repeatable delivery and arm action that allows him to pound the strike zone with three pitches. His fastball ranges from 88-92 mph and touches 94 with late life up in the zone. His best secondary is a sharp, 77-80 mph curveball that he shows a natural feel to spin, and he rounds out his arsenal with a changeup that flashes average but lacks consistency. Morales has room to get stronger and add velocity and power to all his pitches. He is extremely intelligent and has an advanced understanding of pitch design and high-tech training methods.
    The Future: Morales has many years of strength gains ahead, but he has the potential to be a back-of-the-rotation starter if everything clicks. He is expected to be ready for 2022 spring training.

  18. 18. Starlin Aguilar | 3B
    Starlin Aguilar
    Born: Jan 26, 2004
    Bats: L Throws: R
    Ht.: 5'11" Wt.: 170
    Drafted/Signed: Dominican Republic, 2021.
    Signed By: Audo Vicente/Rafael Mateo.

    Track Record: Aguilar was one of the best hitters his age in the Dominican Republic and trained in the same program that produced Red Sox third baseman Rafael Devers and Rays shortstop Wander Franco. The Mariners locked on to Aguilar early and signed him for $1.5 million, the highest bonus they awarded in the 2020-21 international class. Aguilar got off to a slow start in the Dominican Summer League in his pro debut, but he finished strong with a .270 batting average and .413 on-base percentage in September.
    Scouting Report: Like Devers, Aguilar is a big-bodied third baseman with a sweet lefthanded swing. He has a fluid, compact stroke, gets on plane early and stays through the ball. He controls the strike zone and has good hand-eye coordination that allows him to cover the entire plate. Aguilar makes a lot of soft contact and is still learning to pick out pitches he can drive. He has above-average raw power, but his contact-oriented approach limits him from accessing it. Aguilar is a below-average runner who will have to watch his conditioning. He needs to improve his footwork and range to become an average defender.
    The Future: Aguilar’s conditioning and power production will determine whether he reaches his everyday potential. He’ll make his stateside debut in the Arizona Complex League in 2022.

  19. 19. Taylor Dollard | RHP
    Taylor Dollard
    Born: Feb 17, 1999
    Bats: R Throws: R
    Ht.: 6'3" Wt.: 195
    Signed By: Ryan Holmes.
    Minors: 0-1 | 0.00 ERA | 4 SO | 3 BB | 5 IP

    Track Record: Dollard pitched two seasons in relief at Cal Poly before moving into the starting rotation as a junior. He made only four starts before the 2020 season shut down due to the coronavirus pandemic, but the Mariners saw enough to select him in the fifth round and sign him for $406,600. Dollard made his pro debut in 2021 and struggled to a 5.14 ERA across both Class A levels, but he struck out 11.4 batters per nine innings while showing underlying promise on high-performance analytics models.
    Scouting Report: Dollard moves well through his athletic delivery and pounds the strike zone with plus command and control. He is an “elite mover” in the words of one evaluator and has caught the attention of opposing teams who think they can unlock more stuff given his delivery and athleticism. Dollard’s stuff is mostly average at present. His fastball sits 91-92 mph and occasionally touches 94, and he has a good feel for using his above-average slider. His curveball and changeup are fringy pitches he’ll use to steal a strike or disrupt batters’ timing. Dollard has room to get stronger and fill out his frame, but he’s likely to always be a control-oriented pitcher.
    The Future: Dollard has a chance to be a back-of-the-rotation starter if his stuff makes the anticipated leap. He’ll see Double-A in 2022.

  20. 20. Michael Arroyo | SS
    Michael Arroyo
    Born: Nov 3, 2004
    Bats: R Throws: R
    Ht.: 5'10" Wt.: 160

    Track Record: Arroyo was the top-paid player out of Colombia in the 2021-22 class, signing for $1.375 million when the international signing period opened in Jan. 2022.
    Scouting Report: Arroyo is an offensive-oriented shortstop with some of the best plate discipline in his international class. Not only does he recognize pitches well and not chase much off the plate, he makes good swing decisions to hunt for pitches in zones that are conducive to his swing path. With quick hands and a compact stroke, Arroyo makes frequent contact in games, using the whole field with what might always be a hit-over-power approach, but a chance to grow into average power. A shortstop for now, Arroyo’s defense would be stretched thin there, but he could develop into an average defender at second or third base, with average speed and arm strength.
    The Future: Given his approach and hitting ability, Arroyo has the offensive attributes that should translate to early success in his pro career, starting with the Dominican Summer League in 2022.

  21. 21. Victor Labrada | OF
    Victor Labrada
    Born: Jan 16, 2000
    Bats: L Throws: L
    Ht.: 5'9" Wt.: 165
    Signed By: Audo Vicente.
    Minors: .161/.212/.290 | 0 HR | 2 SB | 31 AB

    Track Record: Labrada hit .350 as Cuba’s leadoff hitter and team captain at the 2018 Pan-American Championships and briefly played for Industriales in Cuba’s major league. He relocated to the Dominican Republic in 2019 to sign with an MLB team and agreed to a $350,000 bonus with the Mariners. After waiting out the coronavirus pandemic, Labrada made his pro debut in 2021 and hit his way out of Low-A Modesto to finish the season at High-A Everett.
    Scouting Report: Labrada is a throwback as an undersized, high-energy center fielder who slaps the ball around and lets his speed work. He has plus-plus speed and always runs hard, including coming on and off the field between innings. He energizes his teams and sets the tone atop the lineup. Labrada can be aggressive at the plate, but he stays in the strike zone and makes a lot of contact with a quick, compact swing from the left side. He has a chance to be an average hitter but gets in trouble when he tries to chase power, which he lacks the strength to generate. Labrada’s speed and range allow him to outrun bad reads or jumps in center field. He has a chance to be an above-average defender with below-average arm strength.
    The Future: Labrada projects to be a high-energy fourth outfielder. He’ll see Double-A in 2022.

  22. 22. Bryce Miller | RHP
    Bryce Miller
    Born: Aug 23, 1998
    Bats: R Throws: R
    Ht.: 6'2" Wt.: 180
    Signed By: Derek Miller
    Minors: 0-0 | 3.18 ERA | 6 SO | 0 BB | 6 IP

    Track Record: The Marlins drafted Miller in the 38th round in 2018 out of Blinn (Texas) JC, but he instead transferred to Texas A&M and spent two seasons in the Aggies’ bullpen before moving into the rotation as a senior. He finished among the team leaders in wins, innings and strikeouts in 2021, leading the Mariners to draft him in the fourth round and sign him for $400,000. Miller went straight to Low-A Modesto after signing and struck out 15 batters in 9.1 innings, although he also gave up 15 hits.
    Scouting Report: Miller’s fastball sits 93-94 mph as a starter and ramps up to 96 with hard ride as a reliever. His average mid-80s slider with hard, late turn misses bats to give him an effective secondary pitch and his low-80s changeup with deception and fade has flashed average, although it was below-average in his pro debut. He also has a fringy curveball. Miller is durable, but he struggles with consistency and is most effective in short spurts. His control is fringy and he relies more on overpowering hitters than hitting his spots.
    The Future: Miller will start for now, but the Mariners acknowledge his future is likely in relief. He has a chance to be a high-leverage, late-game reliever if everything comes together.

  23. 23. George Feliz | OF
    George Feliz
    Born: Sep 21, 2002
    Bats: R Throws: R
    Ht.: 5'11" Wt.: 160
    Signed By: Audo Vicente/Alfredo Celestin

    Track Record: The Mariners signed Feliz for $900,000 out of the Dominican Republic in 2019, the largest bonus of their international class that year. Feliz’s pro debut was delayed by the coronavirus pandemic, but he impressed when minor league play resumed in 2021. He hit .277/.362/.451 in the Dominican Summer League and showcased noteworthy athleticism and tools.
    Scouting Report: Feliz is one of the best pure athletes in the Mariners’ system. He is a plus runner who covers plenty of ground in center field to project as an above-average defender, has above-average arm strength and flashes above-average raw power. The question is how much contact he will make. Feliz has plenty of bat speed and strength, but he lacks natural rhythm and timing as a hitter and doesn’t use his lower half well in his swing. He has gotten quieter and calmer at the plate and improved at staying balanced and keeping his back foot on the ground, but a fringe-average hitter is his best-case scenario.
    The Future: Feliz needs to prove he can hit, but his tools and athleticism will buy him time. He is set to move to the Arizona Complex League in 2022.

  24. 24. Kevin Padlo | 3B
    Kevin Padlo
    Born: Jul 15, 1996
    Bats: R Throws: R
    Ht.: 6'2" Wt.: 200
    Drafted/Signed: HS--Murietta, Calif., 2014 (5th round).
    Signed By: Jon Lukens (Rockies).
    Minors: .211/.348/.421 | 2 HR | 3 SB | 38 AB

    Track Record: Padlo starred in both baseball and basketball in high school and was drafted by the Rockies in the fifth round in 2014. Colorado traded him to the Rays two years later in the deal that sent German Marquez to the Rockies. Padlo made his major league debut with the Rays in 2021 before being claimed off waivers by the Mariners in August, and he summarily hit eight homers in 26 games at Triple-A Tacoma.
    Scouting Report: Padlo is a good athlete with plus-plus raw power. He hits towering fly balls to his pull side and has improved at picking out pitches to drive. He posted back-to-back 20-home run seasons in the minors and has the power to do the same in the majors, but that will depend on him getting enough at-bats. Padlo has a pull-heavy approach that leaves a lot of holes in his swing. He’s a below-average hitter who relies on making impact on contact. Padlo is an average defender at third base who moves well for his size and has above-average arm strength. He is also experienced playing first base and second base.
    The Future: Padlo’s power and infield versatility give him a chance to stick in a reserve or platoon role. He’ll return to the majors in 2022.

  25. 25. Wyatt Mills | RHP
    Wyatt Mills
    Born: Jan 25, 1995
    Bats: R Throws: R
    Ht.: 6'4" Wt.: 190
    Drafted/Signed: Gonzaga, 2017 (3rd round).
    Signed By: Alex Ross/Jeff Sakamoto.
    Minors: 1-0 | 3.00 ERA | 2 SO | 1 BB | 6 IP

    Track Record: A Washington native, Mills finished second in Gonzaga history with 21 saves and was drafted in the third round by the Mariners in 2017. He was solid but unspectacular his first few seasons and was not invited to the Mariners alternate training site in 2020, but he reported to instructional league throwing harder and was added to the 40-man roster after the season. He followed by averaging 16 strikeouts per nine innings at Triple-A Tacoma in 2021 and made his major league debut with 11 appearances for the Mariners.
    Scouting Report: Mills is a classic sidearm reliever who relies on keeping the ball on the ground with his sinker and slider. His sinker sits 92-93 and touches 97 with late armside run that locks up righthanded batters. His average mid-80s slider sweeps horizontally across the plate out of his arm slot that is nearly parallel to the ground. Mills scrapped his changeup to focus on his two best pitches, helping them play up but leaving him vulnerable against lefties. He has average control and relies more on movement and deception than precision.
    The Future: Mills will contend for a spot in the Mariners’ bullpen in 2022. He projects to settle in as a middle reliever who matches up against a run of righthanded hitters.

  26. 26. Jonatan Clase | OF
    Jonatan Clase
    Born: May 23, 2002
    Bats: L Throws: R
    Ht.: 5'9" Wt.: 180
    Drafted/Signed: Dominican Republic, 2018.
    Signed By: Audo Vicente.
    Minors: .353/.450/.529 | 1 HR | 7 SB | 34 AB

    Track Record: Clase signed with the Mariners for $35,000 during the 2018 international signing period and quickly emerged as a potential steal. He hit .300 with 21 extra-base hits and 31 stolen bases in his pro debut in the Dominican Summer League, but injuries have sidetracked his development. Clase suffered repeated hamstring and quad strains over the last two years and played only 14 games in the Arizona Complex League in 2021.
    Scouting Report: Clase is a nearly 80-grade runner who gets to top speed quickly and wreaks havoc on the basepaths. He uses his speed to cover wide swaths of ground in center field and has good instincts for the position, helping him project to be at least an above-average defender with an average arm. Clase has excellent strike-zone awareness and began switch-hitting in 2021 after previously batting only lefthanded. He is naturally righthanded and shows the potential to be an average hitter from both sides. He has added strength since signing, but power is not his game. Clase’s main challenge is staying healthy. He has played only 77 games in three years and has missed a lot of crucial development time.
    The Future: Clase needs to show he can stay on the field. If he can, his speed, defense and switch-hitting ability make him a potential breakout candidate.

  27. 27. Devin Sweet | RHP
    Devin Sweet
    Born: Sep 6, 1996
    Bats: B Throws: R
    Ht.: 5'11" Wt.: 183
    Signed By: Ty Holub.
    Minors: 1-1 | 6.75 ERA | 7 SO | 2 BB | 7 IP

    Track Record: Sweet spent four years in North Carolina Central’s rotation and graduated as the program’s all-time leader in wins (18) and strikeouts (246) in 2018. He signed with the Mariners as an undrafted free agent for $5,000 and quickly surpassed many of the players picked instead of him. Sweet rose to Double-A in 2021 and struggled with a 5.65 ERA as a starter, but he moved to the bullpen at midseason and dominated with a 0.63 ERA in relief.
    Scouting Report: Sweet’s success centers around his changeup, a plus-plus pitch in the 78-80 mph range with late dive and fade. It dies late to get foolish swings and misses out front even when batters are looking for it. Sweet has a good feel for moving his changeup around the strike zone and will throw it against any hitter in any count. Sweet’s 92-94 mph fastball serves solely to set up his changeup and he scrapped his below-average curveball once he moved to the bullpen. He has above-average control and limits self-induced mistakes like walks, hit batters and wild pitches.
    The Future: Sweet’s changeup alone gives him a chance to be an effective middle reliever. He’ll move to Triple-A Tacoma in 2022.

  28. 28. Cade Marlowe | OF
    Cade Marlowe
    Born: Jun 24, 1997
    Bats: L Throws: R
    Ht.: 6'2" Wt.: 200
    Signed By: John Wiedenbauer
    Minors: .156/.250/.250 | 1 HR | 2 SB | 32 AB

    Track Record: Marlowe started all four years at Division II West Georgia and set the program’s single-season and career stolen base records. The Mariners drafted him in the 20th round in 2019 and signed him for $5,000. Seattle’s front office analysts highlighted Marlowe as a breakout candidate before the 2021 season, and he loudly lived up to that prediction. Marlowe led the minor leagues with 107 RBIs as he advanced from Low-A Modesto to High-A Everett and was the only player in the minors to record at least 20 doubles, 10 triples, 20 home runs and 20 stolen bases.
    Scouting Report: Marlowe has plus speed, is an above-average defender in the outfield and has plus raw power he gets to in games. He makes loud contact when he connects and has the combination of speed and strength to rack up extra-base hits. Marlowe has a sound approach and controls the strike zone, but he is prone to swinging and missing in the zone. Some are optimistic he’ll make adjustments, but others fear he’ll struggle to make contact against better pitching. Marlowe is very smart and has an elite work ethic. He had a 3.87 GPA as a pre-med/biology major and planned to be a doctor before he was drafted.
    The Future: Marlowe will move to Double-A in 2022. It will be a prime chance for him to prove he can hit age-appropriate pitching.

  29. 29. Kaden Polcovich | 2B/OF
    Kaden Polcovich
    Born: Feb 21, 1999
    Bats: B Throws: R
    Ht.: 5'10" Wt.: 185
    Drafted/Signed: Oklahoma State, 2020 (3rd round).
    Signed By: Jordan Bley.
    Minors: .148/.207/.296 | 0 HR | 0 SB | 27 AB

    Track Record: Polcovich, the son of former Pirates infielder Kevin Polcovich, put together a strong summer in the Cape Cod League before his junior year and was off to a hot start for Oklahoma State before the coronavirus pandemic canceled the 2020 college season. The Mariners drafted him in the third round and signed him for $575,000. Polcovich made his pro debut at High-A Everett in 2021 and earned a midseason promotion, but he hit just .133 in 36 games at Double-A.
    Scouting Report: Polcovich’s best attribute is his defensive versatility. He is a good athlete and above-average runner who can play second base, third base and all three outfield positions at an average or better level. He has advanced defensive instincts and average arm strength that plays anywhere. Polcovich is a below-average hitter who takes swings that are too big for his 5-foot-10, 185-pound frame and his power is also below-average. A switch-hitter, he has more thump in his bat from the left side.
    The Future: Polcovich’s defensive versatility gives him a chance to reach the majors as an up-and-down utility player. He’ll see Triple-A in 2022.

  30. 30. Penn Murfee | RHP
    Penn Murfee
    Born: May 2, 1994
    Bats: R Throws: R
    Ht.: 6'2" Wt.: 195
    Signed By: Jordan Bley.
    Minors: 2-0 | 0.00 ERA | 10 SO | 2 BB | 8 IP

    Track Record: Murfee spent his first two seasons at Vanderbilt as an infielder before converting to pitching as a junior. He transferred to Santa Clara for his senior season and showed enough for the Mariners to draft him in the 33rd round and sign him for $5,000. Murfee took off and vaulted three levels up to Triple-A in his first full season. He spent 2020 at the alternate training site and returned to the upper levels in 2021, where he went 7-3, 4.23 with 97 strikeouts in 78.2 innings while working effectively as both a starter and reliever.
    Scouting Report: Murfee is older at 27, but he’s young in pitching experience and has progressed rapidly in a short time. His low-90s fastball plays up with deception out of his low arm slot and his low-80s slider is a swing and miss pitch with late dive and tilt that gets swings and misses from hitters on both sides of the plate. He throws his slider more frequently than his fastball and can land it for strikes in addition to getting swings and misses. Murfee is an extremely intelligent pitcher who knows how to set hitters up, read their swings and has enough command to hit his spots. He has to work the edges of the plate and will walk batters, but he has average control.
    The Future: Murfee’s funk, command and smarts give him a chance to be a low-leverage reliever. He is in position to make his debut in 2022.
