LHP Renn Fiss (Lafayette, 2025) toes the rubber at a projectable 6-foot-3, 185-pounds. Working from the stretch only, Fiss’ arm draws short out of his glove and works from a tight window, creating slight run on an 80-83 mph fastball. He created natural fade on a changeup at 72-75 mph that played from a window out of the hand to his fastball and he also flashed feel to land a 70-71 mph slider for strikes.
