Kyle Fetherolf: RHP/OF, (2024) Troy High School, MI. 6-foot-1, 175-pound. Smooth solid on the mound, using a long arm action he showed good arm speed from an over-the-top arm angle. Tall-and-fall type pitcher and shows some effort. Showed consistent strong balance point with even shoulders. Lands open with balanced finish. Had running action and control some around the zone with tight movement. (Max spin 1801; Avg 1691). He showed feel around the zone command and slurvey action on his 11/5 slider. (Max spin 1738; Avg 1715).
