RHP Luke Klunke (Normal Community, 2025) made his Prep Baseball event debut last Wednesday and impressed. An athletic 5-foot-11, 180-pound build, Klunke displayed a low-80s fastball that was up to 85.1 mph with a max of 17” of horizontal movement. He mixed in a mid-70s slider with short, horizontal break, as well as a mid-70s changeup that had arm-side fade at times, but was mostly straight.
