Jack Zimmerman is a rising lefty with real strikeout juice for Dayton
In the 2026 season, Dayton freshman left-hander Jack Zimmerman logged a 4.00 ERA across 12 appearances, with 9.0 innings, 6 strikeouts, 7 walks, and a 1-0 record — a small sample, but enough to show a live arm and some early leverage potential.[3][4] His calling card is left-on-left value and a proven strikeout pedigree: he arrived after a high-school senior year with 99 strikeouts and a 1.70 ERA, and local coverage described him as a pitcher who “can sling it,” which fits a competitive, high-energy profile.[7][15] If a team wants a young southpaw with upside and room to polish command, Zimmerman looks like a worthwhile bet.
