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
Slider
Hammer+
A hammer breaking ball drops vertically with velocity through the zone, or 12-to-6 movement. Hammer+ of 100 is MLB average.
Slider
Sweep+
A sweeping breaking ball moves horizontally with velocity through the zone. Sweep+ of 100 is MLB average.

5-foot-6, 160-pound right-handed pitcher and right-handed hitting infielder. On the mound, the fastball sat 84-85 mph with arm side run to it. The spin pitch was a slider at 69-70 mph and solid in shape. The changeup was 76-77 mph with minimal fade to it. He also showed a breaking ball at 68-69 mph that was big in shape. The approach in the infield was solid, throwing 82 mph. The bat had an exit velocity of 88 mph. The setup was narrow in base and the front foot gains ground to the baseball. The hands work freely.
