LHP Ryan Brennecke (Oconomowoc, 2025) was another arm that earned multiple appearances for Team Wisconsin down in Georgia, continuing to display an increase in velocity. Brennecke, standing at an athletic 6-foot-2, 189-pound frame, was a standout in the spring for Oconomowoc. After quality work throughout the summer, he earned his invite to LakePoint with Team Wisconsin. The current No. 1 left-hander in the Badger State’s 2025 class rushed his fastball up to 87.6 mph, jumping on batters in a quick fashion. While working efficiently on the bump, Brennecke flipped up a curveball and changeup to alter the pace, playing off of his heavy fastball usage. The arsenal that Brennecke presented in front of our staff was noteworthy throughout the three games of play, especially coming from the left side, projecting him as a name-to-know in the near future.

LHP Ryan Brennecke (Oconomowoc, 2025) is a strong 6-foot-2, 190-pound sophomore southpaw who has impressed our staff on several occasions already, as a competitive strike-thrower with upside. He looked good again on Saturday, sitting 82-83 mph, with hard arm-side life that he locates well. The changeup is already an out-pitch, tunneling exceptionally well off his fastball with late fade that added to its deception. Brennecke also showed improved feel for a short breaking ball that should grow into a reliable third pitch for him. The feel three-pitch mix, above-average control for his age, and his left-handedness contribute to his status as a top-20-ranked with an arrow up still.
