It’s safe to say Milwaukee Brewers flamethrower Jacob Misiorowski was more than ready for his first showdown with the New York Yankees on May 8. The young right-hander didn’t just pitch—he made history, all within a single, jaw-dropping first inning.

Coming within an eyelash of an immaculate inning, Misiorowski threw just 10 pitches—every single one clocked at over 102 miles per hour—and worked a perfect 1-2-3 frame with two strikeouts. But the real fireworks came when he faced Yankees slugger Aaron Judge. Misiorowski’s final pitch of the inning, a 103.6 mph fastball that Judge flew out on, set a record as the fastest pitch ever thrown by a starter in the pitch-tracking era (since 2008).

That wasn’t the only record to fall. Misiorowski’s second pitch to Judge, at 103.5 mph, also set a mark. His third, at 103.1, barely missed the plate, so he came back with the 103.6 mph heater to induce a flyout to Sal Frelick. In total, he threw the five fastest pitches ever tracked for a starting pitcher—all in that first inning alone.

Before the night began, only three fastballs by a starter had ever reached 103 mph in the pitch-tracking era (Misiorowski had thrown one of them). He then hurled seven such pitches in just the first inning, matching his own record with two 103.6 mph seeds to Spencer Jones before striking him out on an 89 mph curveball. By the end of the frame, Misiorowski had nine pitches of 103 mph or more; the previous record for a full big-league appearance was 12.

Misiorowski got former Brewers outfielder Trent Grisham and Ben Rice on swinging third strikes for the first two outs, setting the stage for his historic showdown with Judge. It was a stunning performance, especially considering he left his previous start on May 1 after experiencing hamstring cramping following 5⅓ no-hit innings in Washington, D.C. With two perfect innings to start May 8, he had recorded 25 consecutive outs since allowing his last hit.

For fans of the game—and of high-octane pitching—this was a night to remember. Jacob Misiorowski didn’t just face the Yankees; he rewrote the record books, one blazing fastball at a time.
