Pitch Scores
2026
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.

RHP Cooper Chapple (Waubonsie Valley, 2027) is an uncommitted arm to continue to follow after the event. Presenting a wiry frame at 6-foot-3, 165-pounds with room to mature physically in the coming years, he showed an intriguing three-pitch mix. His fastball sat 85-87 mph with arm-side run (avg. 16.4” HM). He tossed in a 70-74 mph curveball with above-average spin (avg. 2379 rpm), and rounded things out with a 73-76 mph changeup that displayed significant fade (avg. 17.6” HM). Chapple will be a name to watch this spring.
