Positional Profile: SS/RHP
Body: 5-8, 140-pounds.
Delivery: Repeatable delivery with an athletic operation and a whippy arm action from a 3/4 slot. Shows feel for his offspeed offerings while staying on line to the target throughout most of the delivery. Makes decent use of the lower half and finishes with healthy arm deceleration. Will occasionally pull off toward the glove side when trying to overthrow.
Arm Action: RH
FB: T80, 79-80 mph. T2144, 1994 average rpm.
SL: 70-72 mph. T1908, 1862 average rpm.
CH: 74-76 mph. T1838, 1729 average rpm.
ATH: 7.28 runner in the 60. 1.73 and 3.99 in the 10 and 30 yard splits. 22.60 max vertical.
Positional Profile: SS/RHP
Body: 5-8, 140-pounds.
Hit: LHH. Wide base with the hands starting high before working down into a strong launch position. Small stride that lands slightly closed. Shows good use of the lower half, though can become rotational at times. Uphill bat path with present feel for the barrel and an approach geared toward lifting the baseball.
Power: 93 max exit velocity, averaged 84.0 mph. 324' max distance.
Arm: RH. INF-88 mph.
Defense: Athletic defender with smooth actions and soft hands on the dirt. Comfortable working through plays with a short, quick arm action that produces accurate throws. Shows the ability to throw effectively from multiple arm angles and projects as a reliable infielder.

Can land closed at times. Uphill bat path. Can fight the front side and will fall over the dish after the swing. Tends to lose posture during the swing. 59.7 mph bat speed with 10 G's of rotational acceleration.
Power: 88 max exit velocity, averaged 75.7 mph. 327' max distance.
Arm: RH. INF-78 mph. Shorter arm action with a clean transfer. Ball shows decent carry and he consistently follows through to the target, keeping throws accurate and on line.
Defense: Smooth and controlled with both glove and feet. Shows good rhythm through the baseball and stays on line to his target. Quick twitch in the step helps him get into position efficiently.
