Notes

4/01/25
Illinois commit. Currently ranked No. 9 in the state. Physically imposing 6-foot-6, 205-pound frame with room for added strength. Started on the bump for the RedHawks and showed upside throughout his outing. Simple delivery with long strides down the mound. He has a loose and quick arm, releasing the ball from a ¾ slot. His fastball was playing with heavy armside run early, sitting 87-89 mph, T90, while settling in at 87-88 mph later in the outing. His breaking ball sat 74-75 mph with depth and created swing and miss at times. Struck out seven over four and a third. Flinn is a high-follow name in the 2025 class and could garner MLB Draft attention throughout the spring and summer.

The big southpaw will be one of the top arms in the state this coming spring, boasting a low-90s fastball that plays up thanks to his long-levered frame with a swing and miss slider to pair.

Illinois commit. Currently ranked No. 140 in the state, Flinn got the start for the RedHawks and showed high upside throughout his start. He is every bit of 6-foot-6, 200-pounds with room to still grow into the frame. He is a loose and athletic mover down the mound, working in-sync with his long levers. His fastball plays with late, hard life through the zone at 88-90 mph, seemingly getting quality extension on the pitch. His go-to off-speed offering was a sweeping-type breaking ball that he was confident throwing to both sides of the plate; back-dooring right-handed hitters or throwing it at their back foot. To complement his repertoire, he pounded the zone with both pitches to make for a 77% strike clip in the outing. The southpaw is a tough matchup for any lineup he opposes, and he more than held his own against the No. 1 team in the state; finishing with six strikeouts over his five innings of two-run ball.
