Pitch Scores
2024
Fastball
Hop+
A fastball with hop has a flat approach angle and visually jumps through the zone. When thrown up in the zone, it is more likely to generate a higher swing and miss average. Hop+ of 100 is MLB average.
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
Slider
Hammer+
A hammer breaking ball drops vertically with velocity through the zone, or 12-to-6 movement. Hammer+ of 100 is MLB average.
Slider
Sweep+
A sweeping breaking ball moves horizontally with velocity through the zone. Sweep+ of 100 is MLB average.

Schaefer picked apart his opponents on the mound on Thursday, working a fastball-curveball combination in an effective fashion. The left-hander presents a long, athletic frame on the bump, standing at 6-foot-0, 155 pounds. He used those fluid movements and smooth actions to cover bases throughout the game as well. Schaefer struck out 11 batters on the day, earning the victory while keeping his team in the game, in which they only gave him one run of support before the seventh inning. The to-be sophomore continues to project as an arm, maintaining similar velocities from his showcase over the winter.

LHP/OF Bron Schaefer (Kaukauna, 2026) is listed at a projectable 5-foot-11, 145 pounds, with long levers. He shined on the mound where he showed an uptempo drop-and-drive delivery with a fastball that sat 75-77 mph (77.9 max) with arm-side run and carry through the zone. He showed above-average offspeed feel for his age, on a curveball with 1/7 sweeping break and the ability to land it for strikes. Schaefer’s changeup has fade and depth, and he was able to locate the pitch low and away. To round out his arsenal, he showed a slider that played similar to his curveball with less bite. From the outfield, Schaefer showed off his strong arm with a max velocity of 82 mph. During batting practice, he repeated line drives through the middle; reached a max exit velocity of 82.6 mph.
