Bay Area World Series 2022 - Uncommitted; Lean athletic body, first look will keep eyes on him, easy arm with quick arm speed, FB up to 84.5 mph with lower spin which given the release and slot present the FB as a sinkerball with ability to work in the lower part of the zone, strong extension numbers with avg of 6.0, a slightly lower slot and focusing on letting the low spin carry the ball to the bottom of the zone is a way a coach could evaluate his stuff, CB and SL have similar spin, both average just over 2000 rpm, working to develop just one of them vs having two similar breaking balls separated by just a few MPH could be an area of improvement., a bit more depth on the CB vs the wider slider, also used CHG that he showed feel for, he's one to keep an eye heading into his senior season.
