Kai-Wei Teng

Organization Prospect Rankings

• 
  Ranked San Francisco Giants #19 prospect in 2020
  TRACK RECORD: The Twins signed Teng for $500,000 as a part of their 2017 international class on the strength of an advanced pitch mix and excellent command for a pitcher his age. Teng was sent to San Francisco at the trade deadline as part of a deal for reliever Sam Dyson. Teng split his 2019 between each organization's low Class A affiliate and showed excellent feel to pitch at both stops.
  
  SCOUTING REPORT: Giants evaluators were pleasantly surprised by what they saw once Teng got into their system. He showed a three-pitch mix fronted by a low-90s fastball which peaked at 93 mph. He threw the fastball less than 50 percent of the time, however, and relied more often on his slider and changeup. The Giants are working with Teng to increase the spin efficiency on his fastball. Both of Teng's offspeed pitches project to be above-average, and their effectiveness is amplified by his ability to consistently throw them for strikes. He did an excellent job pounding the strike zone overall and threw 66 percent of his pitches for strikes.
  
  THE FUTURE: Teng will advance to high Class A San Jose in 2020 and has the ceiling of an innings-eater at the back of a rotation.

• March, 2021 Scouting Report
  TRACK RECORD: The Twins signed Teng in 2017 because of an intriguing combination of stuff and command. They dealt him to the Giants along with righthander Prelander Berroa in exchange for reliever Sam Dyson at the 2019 trade deadline. Teng stayed in his native Taiwan throughout the coronavirus pandemic and did not attend instructional league in the fall.
  
  SCOUTING REPORT: Teng boasts a three-pitch mix with a low-90s fastball that topped out at 93 mph the last time he pitched. He pairs his fastball with a slider and changeup that each project as above-average with further refinement. Teng mixes his pitches a little bit differently than most in that he throws his fastball less than 50% of the time. The Giants previously worked with Teng to improve the spin efficiency on his fastball, which plays better than its velocity because of how often he can throw his offspeeds for strikes. He commands his arsenal expertly with above-average control.
  
  THE FUTURE: Teng's varied mix and excellent pitchability give him a chance to move quickly. He has a chance to see the upper levels in 2021.
