  Scouting Report & Links      
  Physical Description: Athletic build. On the thin side. Has some projection left in his upper half and should add strength as he matures.

Mechanics: Throws from a three-quarters arm slot, starting on the first base side of the rubber. Pronounced leg kick with large stride towards home plate. Short arm action and hides the ball behind. Falls off to the first base side post-delivery, sometimes significantly. Effortful but not violent arm mechanics. With runners on base, uses a much shorter leg kick.

Fastball: 93-95 mph, topping out at 98mph. Has fringy life and is on the straight side. Below-average command at present. Has not shown the ability to consistently miss bats in the low minors. Also throws a two-seam fastball with late downward movement. Potential average offering.

Changeup: 80-82 mph. Pitch shows late, downward movement. Can pull the string on it and have it fall off the table late. Throws with deceptive arm speed. Pitch was inconsistent and lacked feel in outings scouted in 2022. Used to throw a splitter also, but shelved the pitch in 2021. Potential fringe-average offering.

Slider: 83-86 mph. Shorter, 10-to-4 shape. Pitch is inconsistent; does not always snap it off. When he does, pitch has flashed bat-missing ability. Can land for a strike or bury down and out of the zone. Potential solid-average offering.

Curveball: 78-80 mph. Vertical with longer break. Get-me-over pitch designed to steal a strike. Potential below-average offering.
  Career Notes: Two-way player in high school who was also a switch-hitting shortstop. Showed great range and athleticism at short. Was reportedly overused on the mound. Pitched for Taiwan in the 2017 U-18 World Cup. Went to Culture University out of high school rather than enter the CBPL draft. Took a break from pitching for two seasons to rest his arm. Returned to pitching in 2019, dialing his fastball up to 98 mph. Was named MVP of the 2019 Asian Baseball Championship, where he was a teammate of Tzu-Wei Lin. Did not pitch much in 2020 spring training because the team had him quarantine after arriving in Fort Myers during the early stages of the COVID-19 pandemic, and camp was ended before he could really take the mound. Participated in 2020 Fall Instructional League, essentially his stateside debut. At Instructs, his velocity was down (fastball was 88-92 mph) and none of his pitches projected as better than average. In 2021, velocity started to tick back up and secondaries showed more potential, but his velocity was still down from where he was reportedly at before he signed. Still was promoted from the FCL to Low-A Salem after a single start, largely based on a strong Extended Spring Training showing. Participated in the Fall Performance Program in 2021.

Summation: Potential minor league depth arm. Ceiling of an organizational arm. Frame is fairly slight to handle the rigors of starting long-term and he has not yet shown consistency with his stuff from outing-to-outing and year-to-year. Strong candidate to move to the bullpen. Still has a wide range of outcomes, as his stuff and arsenal are constantly evolving with each new look.
