Costabile

RHP/OF Frank Costabile (Stevenson, 2026) two-way: On the mound Costabile showed off a big arm out of a small frame (5-foot-7, 150-pounds). He works with a drop and drive style that works slightly uphill and to the top of the zone with an 86-88 mph fastball. He flashed plus potential on his breaking ball with some serious spin, but will have to harness its command to see its true effectiveness.

OF/C/RHP Frank Costabile (Stevenson, 2026) showed off impressive arm strength for a 2026 graduate. The 5-foot-7, 150-pound two-way prospect ran a 7.23 60-yard dash, topped at 87 mph from the outfield and showed above-average bat speed and power from the right-side of the plate. To top off his impressive day, Costabile got on the mound and sat comfortably at 85-86 mph, touching an 86.8 high – that’s good for the third highest fastball velo across all Rising Stars events in the nation this year. Costabile was impressive across all facets, but his on-mound work was particularly eye-opening. He was reaching that mid-80s velocity with relative ease, and he was generating hard sweeping action with his curveball that was spinning at an advanced rate, and not just for a player his age. His changeup was equally impressive, with late arm-side run and fade that he was spotting effectively at the bottom of the zone. Costabile’s arm strength translated effortlessly into his catcher defense, where he recorded pop times in the 2.13-2.20 range, aided by an arm that topped 78 mph out of the chute.
