INF/C Jack Brenner (Fond du Lac, 2026) is a 5-foot-10, 161-pound infielder and catching prospect that showed well on both sides of the field. At the plate he was able to consistently drive the baseball to both gaps with easy bat and hand speed through the baseball. Defensively Brenner showed steady actions in the infield with some arm strength (T85 mph) that plays across the diamond and while on the move. Behind the plate, Brenner’s arm strength also played behind the plate at 78 mph and was a quality mover out of the crouch.
