Tanner Grindall: 3B/3B, (2023) Portage Central, MI. 6-foot-2, 185-pound. During batting practice, the right-handed hitter's best exit velocity was 87 mph. (67.2 mph bat speed average). (21.3 mph hand speed average). Begins in a wide stance with a high load, then uses a toe tap stride. Has a long swing plane and balanced finish. Line drive approach. Solid in the infield, recorded a position velocity of 81 mph; had a natural exchange, consistent footwork, and firm hands. Fields the ball out front, movements laterally were athletic. Clocked a 60 time of 7.48 at the event. Smooth solid on the mound, used an over-the-top arm angle and a moderate consistent arm action while showing good arm speed. Drop-and-drive type pitcher and shows some effort. Has a strong balance point and even shoulders. Lands open with balanced an athletic finish. Changeup (70-73 mph), slider (71-73 mph). Threw his fastball 76-79 mph; had command around the zone and slight running sinking action with tight movement. (Max spin 1632; Avg 1454). He showed slurvey action and occasional command on his 12/6 curveball.
