OF Jack Stefani (Glenbrook South, 2026) is a 6-foot, 170-pound, athletically-built, switch-hitter to follow in the class. Stefani showed true switch-hit ability with a fluid stroke from both sides, particularly the left, where he flashed loose, quick hands, stayed on-plane with natural lift and drove balls to both gaps. Posted a max exit velocity of 88 mph during BP and his furthest batted ball traveled 330’. Defensively, he flashed steady hands and a quick arm that topped at 82 mph from the outfield.
