12/19/2020 - Winter Pro Training Experience - Nor Cal (HS - Dec) Alvin is a talented OF/RHP prospect in the 2024 class. In the OF, he shows active footwork which allows him to work behind the ball. He gets great reads off of the bat and has + range. He creates momentum into his throws, releasing the ball from a high 3/4 arm slot. At the plate, Alvin starts in a square setup with comfortable hands. He swings on a level path and is able to spray the ball to all parts of the field. On the mound, he shows good poise with the ability to put hitters away. His FB ranged 64-66 with movement, SL showed 11-5 shape, and a knuckleball with sinking action. Alvin is a hard worker who has a ton of upside.
