Jacob Misiorowski pitched tonight, which means records were broken.
However, tonight wasn't just about Misiorowski setting new velocity records, which, of course, he did. Rather, the Milwaukee Brewers' ace turned in the most complete and dominant performance of his young career, and he did it on the one-year anniversary of his major league debut.
Exactly one year after Miz complete five no-hit innings against the St. Louis Cardinals in his first-ever major league start, the Brewers' flame-throwing right-hander faced the minimum against the Philadelphia Phillies, allowed just one, struck out an unbelievable 15 batters, and recorded Milwaukee's first complete game shutout in three years.
It started with a dominant first three innings for Misiorowski, who struck out eight of the nine batters in Philadelphia's lineup the first time he faced them. Only third baseman Alec Bohm made contact in fair territory against Miz through the first three innings of tonight's game, and the result was a lazy groundout to shortstop David Hamilton.
Ironically, after the game Miz told reporters, "To be honest, first few innings, I felt like I didn't have it all that well...I was just hoping they would swing and, you know, they were hacking away, so it helped a lot."
Miz may not have felt like he "had it" through the first third of the ballgame, but the radar gun certainly told a different story. In the first inning, Misiorowski broke the record for the fastest pitch ever recorded in the pitch tracking era (since 2008) by a starting pitcher. It's a record that Miz himself owned prior to today, but he still broke his own record by nearly one full mile per hour. Last week in Colorado, Miz set the benchmark for starting pitchers with a 103.7 mph fastball; tonight he threw the fifth pitch of the game 104.5 mph. In fact, during the first inning of tonight's game, Miz threw a whopping FOUR pitches faster than his previous record, which clocked in at 104.5, 104.2, 104.1, and 104.0 mph.
It wasn't those four pitches alone that etched Misiorowski's name above his own in the record books, but rather the fastballs that he used to strike out Kyle Schwarber, Trea Turner, and Bryce Harper in the first inning also earned Miz a spot in history. As clearly laid out by the great Sarah Langs of MLB.com in the graphic below, Miz's three punchouts in the first came on the fastest three pitches to ever produce a strikeout by a starting pitcher...and they all happened in one inning.

See, while it's impressive in its own right that Misiorowski can consistently run it up north of 103 mph, what makes his performance in the first inning of tonight's game that much more impressive is that he was also painting the corners. Miz's command remained sharp throughout tonight's start, leading to the most dominant outing of his young career.
Jacob Misiorowski turns in the most dominant outing of his career on the one-year anniversary of his MLB debut
After Misiorowski's incredible first time through the Phillies lineup, 3x All-Star and 2025 NL MVP runner-up Kyle Schwarber spoiled what otherwise would have been an even more historic night by dumping a first-pitch slider into center field for a base hit. However, after a strikeout of Turner, Miz got Harper to bounce into an inning-ending double play, keeping him to the minimum number of hitters faced through four frames.
What followed was a masterful performance from Misiorowski in the final five innings. Miz didn't allow another baserunner all night, making Schwarber's hit the only difference between his complete game shutout and a perfect game. Meanwhile, the Brewers' ace racked up six more strikeouts, which brought his total to 15 on the night -- a new career high for Miz. The young flame-thrower previously reached 12 strikeouts twice in his career, once this season against the St. Louis Cardinals and once last year against the Los Angeles Dodgers.
Making matters even better for Miz was the fact that he didn't surrender a single walk tonight. A far cry from the four walks in five innings that he issued during his MLB debut one year ago, tonight Miz's command was picture-perfect and the result was him being able to complete nine innings in just 95 pitches.
When a pitcher throws a complete game in under 100 pitches, it's referred to as "a Maddux," named after the great Greg Maddux, who tossed 13 complete games with fewer than 100 pitches throughout his Hall of Fame career. However, no one since at least 1988, when pitch tracking began, but likely much longer, has ever collected 15 strikeouts in "a Maddux," as noted by MLB.com Brewers' beat reporter Adam McCalvy.
A 15-strikeout masterpiece for Jacob Misiorowski, who blanked the Phillies on 95 pitches. That's a record number of strikeouts for a Maddux (CG in under 100 pitches) since pitch counts started tracking in 1988.

Simply put, Misiorowski was dominant tonight. He racked up the strikeouts early and induced plenty of quick outs in the middle and late innings. It's the first complete game shutout by a Brewers' pitcher since Brandon Woodruff completed the elusive feat back in September of 2023. However, the fashion in which Miz accomplished the feat is more on par with games like CC Sabathia's one-hit shutout back in 2008, and Ben Sheets' 18-strikeout gem back in 2004. Paired with the record-breaking velocity, Miz's performance tonight will go down as one of the best and most memorable in franchise history.
