Jacob Misiorowski, the Milwaukee Brewers' 24-year-old right-hander, threw a record 47 pitches at 101 mph or faster in his start against the Atlanta Braves on June 19, 2026, surpassing his previous record of 45 on June 6 [1]. His fastball reached a peak velocity of 104.5 mph this season, the fastest ever recorded by a major league starting pitcher since pitch-tracking began [1, 2, 3].

In the game, Misiorowski pitched six innings, allowing two runs on five hits while striking out seven. Despite his performance, the Brewers lost 3-2 to the Braves, handing Misiorowski the loss [1]. Prior to this start, he had allowed only one earned run over 54.1 innings in eight starts, holding a major league-leading 1.34 ERA that rose to 1.45 after the outing [1, 3]. He entered the game with an 8-2 record and an excellent WHIP of 0.73 [3].

The 6-foot-7, 201-pound pitcher threw a mix of pitches but relied heavily on his four-seam fastball, which comprised 68% of his arsenal. He also mixes in curveballs, cutters, and changeups [3]. Misiorowski’s strikeout total of 131 leads the majors, along with a strikeout rate of 39.8%, the highest in the league this season [2]. On June 12, he struck out 15 batters in a one-hit shutout against the Philadelphia Phillies, throwing 95 pitches in that dominant outing [1, 2, 3].

Brewers manager Pat Murphy praised Misiorowski despite the loss, saying, “He was great. He was dominant, fantastic. You know, you’re going to give up runs. You’re a human. Go back and look at some of the greats. They all gave up runs. We’re kind of shocked when he gives up a run” [1]. Meanwhile, Braves manager Walt Weiss acknowledged the difficulty of facing Misiorowski: “It’s big-time extension with big-time velocity, so the ball is on you. [He] throws strikes, so you have to be aggressive. You’ve got to be ready to fire. It’s a tough guy to have two strikes against” [1].

Misiorowski said after the game, “I felt fine. They are definitely a really good team. You could see that with all their at-bats today. There wasn’t a single at-bat they were off. They were all trying to fight me through the whole game” [1].

The Brewers face the Braves again in their next scheduled game, giving Misiorowski a chance to rebound and continue his record-setting season.
