OF/RHP Jack Stefani (Glenbrook South, 2026) is an intriguing prospect in the state’s 2026 class. He’s a left-handed hitter at the plate with twitchy actions, producing a max exit velocity of 92 mph, but staying on the barrel for an average of 85.3 mph. From the outfield he showed clean, athletic actions with a long and loose arm, producing an 88 mph bullet on his best ball to home. On the mound, he showed athletic actions, producing a mid-80s fastball that was up to 87.1 mph with quality spin (avg. 2395) and an average of 20.1 inches of horizontal movement. An upside prospect at 6-foot-2, 185-pounds.

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.
