Positional Profile: RHP/SS
Body: 6-foot, 194-pound well-built and mature frame.
Hit: RHH. At the plate starts with an athletic stance and hands set at shoulder height. Rocker type load with a simple stride back to neutral. Short swing with hands working quickly through the zone. Level bat path with line drive approach. Used the whole field well.
Power: 80 mph exit velocity from the tee.
Arm: RH. INF-75 mph. Low ¾ arm slot with stiff arm action working across the body.
Defense: In the infield likes to sit back on the ball and uses short/choppy feet to get around it with rhythm headed towards first. Fields the ball out in front of the body with a feel for glove action. Quickness of exchanges are still developing.
Run: 4.13 runner from home to first.
Delivery: Works exclusively out of the stretch. Slow and deliberate leg lift to balance point. Hand break is out away from chest and drives the lower half down the mound with good direction. Maintains good balance throughout the delivery.
Arm Action: High ¾ arm slot with pushing release.
FB: 76-79 mph, Heavy arm side run and sink.
CB: 66 mph, short break with 11/5 action.
SL: 67 mph, back up action with developing spin.
CH: 63-67 mph, lots of horizontal movement to the arm side with good command.
