RHP Cooper Chapple (Waubonsie Valley, 2026) came to his first Prep Baseball event and showed very well. The right-hander lean, wiry 6-foot-3, 160-pounder sat 84-85 mph with a spin efficiency of 96%. His changeup sat 69-71 mph with an average HM of 15.2 inches. Chapple’s curveball shows a lot of potential as it sits 65-68 mph with an average spin rate of 2339 RPM and an average HM of -18.8 inches while having an average IVB of -12.7 inches.
