Henderson put together arguably the best performance amongst uncommitted positional players. The 6-foot-2, 175-pound outfielder boasted the top velocity at the position at 91mph and had the top 30-yard (3.75s) and 10-yard (1.63s) splits. Henderson also impressed during BP as he put up some big-time numbers during BP and looks to have added some impact in the bat and there’s still plenty of projection and potential strength to come. The right-handed hitter’s max exit velocity of 101.4mph was 5th-best and his 92.1mph average exit velocity was 3rd-best. Henderson is one of the top uncommitted outfielders in Ontario’s 2026 class and should grab plenty of attention throughout the summer.
