Arm: RH. OF - 86 mph. Let it fly with success, 5/5 on throws, good execution overall.
Hit: RH. Wide and slightly open base, step load, good at contact, stiff rotation, two-hand finish. Blast Motion scores of 39/64/27. Above-average connection score shows his ability to stay aligned and get in a good position to hit.
Power: 90 mph exit velocity.
Run: 7.31 runner in the 60.
Body: 6-2, 175-pounds. Long limbs, projectable on the mound and outfield, present strength.
Delivery: Simple mechanics, nothing wasted, would benefit from more lower half engagement.
Arm Action: RH. Arm works cleanly, can see speed in the arm, good follow through, consistent release points.
FB: T83, 79-80 mph. Commanded the fastball well, decent spin rate at 2145.
CB: 70-71 mph. Solid high school curveball showing, compact break to the glove side, fly ball inducing pitch.
SL: 67-70 mph. Played well off the curveball with true slider tilt, good second breaking ball offering.
CH: 72-75 mph. Developmental change, showed some run and fade, works well with fastball and release point.
