Grip Strgth (LH)
Grip strength is a measure of a players bat control and ability to transfer power and speed during impact, measured in pounds of force generated; collected with elbow bent at 90 degrees.
Grip Strgth (RH)
Grip strength is a measure of a players bat control and ability to transfer power and speed during impact, measured in pounds of force generated; collected with elbow bent at 90 degrees.
Positional Profile: RHP/SS
Body: 5-9, 169-pounds.
Delivery: Stretch only with feet set even and hands at stomach height. Raises with the leg lift and follows the glove on the break. Glove works on line to the target with decent lower half involvement. Falls off glove side at times but generally maintains direction. Athletic look on the mound with good balance and limited excess movement.
Arm Action: RH. 3/4 slot with a longer arm action. Slings the ball with healthy deceleration and some looseness through release.
FB: T83, 81-83 mph. Fastball comes out firm and stays on plane through the zone. Shows enough life to miss barrels. T2373, 2175 average rpm.
CB: 67-70 mph. Curveball shows decent depth and shape. Comfortable landing it for strikes and using it to change eye levels. T2268, 2169 average rpm.
SL: 69-70 mph. Slider has more sweep than depth and plays well off the fastball. Can be thrown for strikes and gives him a different look against hitters. T2206, 2146 average rpm.
CH: 75-76 mph. Changeup shows some fade and keeps separation off the fastball. Still developing consistency but works as a usable fourth pitch. T1305, 1126 average rpm.
ATH: 7.69 runner in the 60. 1.87 and 4.30 in the 10 and 30 yard splits.
Positional Profile: RHP/SS
Body: 5-9, 169-pounds.
Hit: RHH. Open stance with neutral hands set near the shoulder. Setup allows him to get started on time. Quick hands and bat speed for his size. Does a good job spraying the ball to all fields and moves well through the swing. 66.4 mph bat speed with 8 G's of rotational acceleration.
Power: 95 max exit velocity, averaged 87.5 mph. 351' max distance.
Arm: RH. INF-81 mph. Shows arm strength with carry across the diamond and consistent accuracy to the target. Comfortable throwing from different arm angles, allowing him to maintain pace on plays while staying on line. Arm plays well in motion and supports throws made on the move.
Defense: Athletic mover with controlled actions and good pre pitch preparation. Plays with rhythm and timing while getting his feet moving in the right direction early. Overall footwork and body control allow him to stay balanced and keep the play moving efficiently.
ATH: 7.69 runner in the 60. 1.87 and 4.30 in the 10 and 30 yard splits.
Vizual Edge: 63.85 Edge Score
