Notes

Comments

4/21/26

Uncommitted. 5-foot-9, 214-pound frame. Entered out of the bullpen and turned in another impressive outing. Maurer works from a ¾ slot with low effort, utilizing a hybrid setup with rhythm in the delivery. He attacked the zone and showed command throughout his two innings of work, throwing 15 of his 20 pitches for strikes. Maurer struck out three, allowed one hit, and did not allow a run while earning the save. An uncommitted name who continues to impress in front of our staff.

4/11/26

Uncommitted. 5-foot-9, 214-pound frame. Entered out of the bullpen and turned in an efficient outing. Maurer works from a ¾ slot with low effort, utilizing a hybrid setup and medium knee lift down the mound. His fastball sat 76-80 mph with natural arm-side run, pairing it with a curveball in the upper-60s that showed tight, short break, and a 71-72 mph changeup with fading action. He limited hard contact and worked efficiently throughout his 3.2 innings. Line: 3.2 IP, 5 H, 0 R, 0 BB, 2 K. An uncommitted name for schools to follow.
