Lengthy, athletic 6-foot-2, 180-pound frame with plenty of projection left. Right-handed hitter with a clean, balanced stroke – fast hands allow him to get on-plane consistently and produce firm contact (91 mph max EV / 317’ peak, 84.9 avg). Shows developing power with a swing that should continue to trend upward as strength arrives. Defensively, arm strength is presently light across the diamond (68 mph), but actions are clean. On the mound, works up to 77 mph with a clean delivery and a whippy arm that suggests more velocity is on the way.
