6-foot-1, 205-pound right-handed pitcher and right-handed hitting corner infielder. He ran a 7.14 sixty at the event. The approach in the infield is appropriate, showing a soft glove and throwing 79 mph across the diamond. The bat has an exit velocity of 88 mph. The setup at the plate even in base and the front foot gains ground as the ball approaches. The hands work loosely and he get the barrel out front. On the mound, the fastball sat 79-80 mph with minimal arm side run to it. The slider is 70-71 mph and solid in shape. The breaking ball is 67-69 mph with depth. The delivery is solid in tempo, forward lean to the process. The arm is long and comes at you out of a 3/4 arm slot.
