Jacob Misiorowski throws record‑fast 104.5 mph pitch in 15‑K shutout vs Phillies

On June 12, 2026, Milwaukee pitcher Jacob Misiorowski delivered a historic performance against the Philadelphia Phillies at American Family Field. He worked a complete‑game shutout, allowing just one hit and no walks while striking out 15 batters on 95 pitches. Misiorowski set a new record for the fastest pitch by a starting pitcher, clocking 104.5 mph – a mark that broke his own earlier record.

The game gave the Brewers a 6–0 victory, with three runs supplied by Jake Bauers’s homer. Misiorowski’s dominant outing earned a Game Score of 100, a rarity surpassed only by a handful of games in MLB history and deemed more exceptional than a perfect game. The 24‑year‑old’s season numbers improved to an 8–2 record and a 1.34 ERA, with a 0.17 ERA over his last eight starts and a 13.4 strikeouts‑per‑nine‑innings rate, placing him among the league’s Cy‑Young candidates.

His 104.5 mph fastball also became the fastest pitch ever recorded for a starting pitcher since MLB began tracking velocities in 2008, further cementing his status as a generational talent.
