Physical: Athletic, projectable 5-foot-8, 152lb frame with some twitch. 7.67 runner in the 60.
Offensively: LHH. Taller, open stance, as the hands started calm, off the shoulder to begin. Utilized a controlled barrel-tip timed up with a leg-lift stride to initiate the swing through a whippy, flat path into the hitting zone. Rotational move across the ball at times, but slotted the barrel cleanly towards a one-handed finish. Notched a T86 mph exit up to 245 feet via Trackman.
Defensively: The outfielder featured momentum-gaining pace into the touch, fielding off his left with a big range of motion from H ¾ slot. Solid posture and reached back for 85 mph positionally, which carried over to the mound with a live fastball.
Pitching: LHP. Southpaw works from the stretch-only off the far right corner of the mound; really counters the forward move and holds direction. Natural body control at 79.6-80.1 mph with a 75% zone rate on the FB. Mixed a plus 69-71 mph SL with feel to spin (2411, 20 inch HM) and added hard-fading 74-76 mph CH the other way.
