Brewers' Jacob Misiorowski Throws Fastest Pitch Ever by a Starting Pitcher in 15-Strikeout Complete Game Shutout

Jacob Misiorowski of the Milwaukee Brewers delivered what may be the finest individual pitching performance in franchise history on Friday night, striking out 15 Philadelphia Phillies batters while allowing just one hit in a 6-0 complete-game shutout at American Family Field before a sellout crowd of 40,205. His 104.5 mph fastball to leadoff hitter Kyle Schwarber in the first inning was the hardest pitch ever thrown by a starter since pitch tracking began in 2008, surpassing his own previous record of 103.4 mph set in May against the Cardinals. Misiorowski threw 58 triple-digit fastballs on the night, including 31 at 102 mph or above, both new records for the pitch-tracking era. The outing also set the record for most strikeouts in a Maddux — a complete-game shutout on fewer than 100 pitches — since pitch counts were first recorded in 1988, surpassing Tarik Skubal's mark of 13 set last year. The overall MLB velocity record still belongs to Aroldis Chapman, who threw 105.8 mph as a reliever for the Cincinnati Reds in 2010. Misiorowski, who made his MLB debut exactly one year prior to Friday's game, has posted a 0.17 ERA over his last eight starts — the lowest such mark in any eight-start span since earned runs became an official statistic in 1913. The performance reignited the NL Cy Young debate between Misiorowski and Phillies lefty Cristopher Sánchez, who has a 1.54 ERA and 113 strikeouts of his own this season.
