Physical: Lean, developing 5-foot-8, 140lb frame with feel present. 8.11 runner in the 60.
Offensively: RHH. Balanced, upright stance, as the hands operate in rhythm to begin. Utilized a toe-tap stride to initiate the swing through a flat path towards a two-handed finish, producing a balanced round to the middle of the field. Got around the ball at times, but shortened up for a T79 mph exit velo (72 mph AVG).
Defensively: The third baseman adjusted depth in the route, able to field softly out in front from the middle of his body. Shuffled directionally towards the target and delivered an accurate throw out of H ¾ slot (72 mph).
Pitching: RHP. Starts off the middle of the rubber; faster, compact delivery that works from a lower release height. The FB jumped at times from 71-72 mph (2400+), mixing an advanced 60-61 mph CB with sharp, lateral bite across the plate.
