LATEST PG SHOWCASE REPORT
2015 Florida Underclass Showcase  
William Kieffer is a 2019 RHP/SS, 3B with a 5-10 155 lb. frame from Loxahatchee, FL who attends Seminole Ridge Community. Medium frame, athletic build with room to fill out. Primary right handed pitcher, compact delivery with solid balance, could use lower half more. Medium arm circle, clean path and arm-action, works to a 3/4's arm slot. Fastball up to 78 mph early, offering has slight cut, does a good job of keeping pitch down in the strike zone. Flashes long-breaking curveball in the mid-60s, developing feel for the pitch. Also uses straight changeup with some deception, works well off of the fastball. Right handed hitter, tall upright setup with slightly open stance. High hands set, upper-body rotational swing, shows inside hand path, works to middle of the field. Also plays infield, developing actions, solid first step and instincts.
