RHP Alex Kronfeld (Holmen, 2024) gave a strong look throughout his ‘pen on Sunday. Built with a strong-bodied, 5-foot-11, 185-pound frame, Kronfield uses a high-intent delivery to produce a fastball up to 87 mph, sitting right at 86 mph throughout his pen. He showed two different breaking balls with a knack to spin both of them; the first being a curveball at 66-69 mph, playing with depth and 11/5 shape. His second breaking ball was a slider at 68-71 mph, playing with more 10/4 shape and flashing sharp action. His final offering was a changeup at 70-75 mph, killing spin and averaging over 15” of run.
