Seattle Mariners

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
