Fastball
Hop+
A fastball with hop has a flat approach angle and visually jumps through the zone. When thrown up in the zone, it is more likely to generate a higher swing and miss average. Hop+ of 100 is MLB average.
Fastball
Sink+
A fastball with sink has low backspin and drops through the strike zone. When thrown down in the zone, it is more likely to generate a higher ground ball percentage and lower launch angle. Sink+ of 100 is MLB average.
Fastball
Rise+
A fastball with rise has a high percentage of backspin. When thrown up in the zone, it is more likely to generate a higher fly ball percentage. Rise+ of 100 is MLB average
Curveball
Hammer+
A hammer breaking ball drops vertically with velocity through the zone, or 12-to-6 movement. Hammer+ of 100 is MLB average.
Curveball
Sweep+
A sweeping breaking ball moves horizontally with velocity through the zone. Sweep+ of 100 is MLB average.

Tall, projectable frame at 6-foot-1, 170-pounds. Starts tall on the mound in the middle of the rubber. Segmented actions in his delivery. Hands stay locked in position until his leg kick. Aggressive frontside helps create hip/shoulder separation. Stride direction stays in line. Compact arm action. High arm slot. FB was located down in the zone 81-82 MPH. CB had 11/5 shape, sharp at times, was 70-71 MPH. Displayed a CH at 74-75 MPH.
6-foot, 158-pound lanky frame. Projectable on the mound, showed quick arm speed with a high ¾ arm angle and a compact arm action. Uses easy effort in his delivery. Showed tall balance point with even shoulders. Lands square. Produced a fastball that came in at 79-81 mph and topped out at 81 mph; showed arm side control and sinking action. His 11/5 curveball (70-71) showed glove side command and tight action.
6-foot, 158-pound lean frame. On the mound, he showed some arm speed, had a long, easy arm action with an high-3/4 angle. He is a tall-and-fall type. Has even shoulders and a tall balance point off the mound. Lands closed. Sat with his fastball at 74-76 mph with a max of 76 mph, shows command of fastball in the zone. Had consistent command on his changeup (68-70) with some armside fade. Threw a 10/4 curveball (64-68) for strikes. Projectable frame, expect velocity to jump as he continues to get stronger.
