02/06/2022 - All-In Membership - Rocklin, CA Boston is a class of 2022 RHP prospect. He shows off a medium sized frame with some room to continue to add strength and size. On the mound, this righty delivers all pitches from a 3/4 arm slot. Shows clean mechanics with a some arm speed. Could see velo go up with more use of his lower 1/2 in his delivery and a structured throwing program. Fastball was 78-81 MPH with some tailing action. Showed feel for both a 11-5 shaped breaking ball along with a changeup with some downhill tumble. Boston is a good player that we expect to possibly have opportunities at the next level.
