Pitch Scores
2024
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.

6-foot, 175-pound right-handed pitcher. The frame is projectable and his actions are athletic. The delivery is solid in tempo and repeated. The arm is slightly above 3/4 and fast. The glove side is under control and the feet are online. He does a good job of getting into the backside to ride the slope and involved his bottom half. The fastball was up to 93 mph with arm side action. The spin pitch is above average, sitting 78-79 mph with plus depth/tilt. The changeup was 78-79 mph with arm side fade to it. Top of the line arm in the country at this age.
Young right-hander, mid to upper 80's with promising secondary stuff. Very quick arm with a chance to be a front line guy down the line.
