Prospect Spotlight

Alonso has a thick and powerful frame that generates plus bat speed and 80-grade raw power. Alonso is a below average runner, but his footwork is good enough to make the routine plays at first base. An average defender, slow foot speed and 40-grade arm strength profiles him best as a 1B/DH option. Offensively, Alonso is aggressive on every pitch and looks to ambush fastballs. His short stroke creates tremendous loft and consistently hard contact that produces 60-grade game power that plays from pole to pole. Alonso is prone to expand the zone in hitters’ counts and to chasing spin. Overall, he is making solid decisions at the plate, and he’s put professional at-bats together throughout the Fall League. His combination of approach, bat-to-ball skills, and tremendous power help project an overall hit tool of 55.
