Milwaukee Brewers ace pitcher Misiorowski delivered a historic performance against the Colorado Rockies on Saturday, throwing 52 pitches at 100 mph or higher—a record for a starrting pitcher since Statcast began tracking in 2008. He also unleashed a 103.7 mph fastball, the fastest recorded from a starter in the Statcast era, according to the report. The outing underscored both his dominance and the emotional toll of elite velocity after he hit Rockies hitter Tyler Freeman in the head with a 98 mph cutter in the sixth inning.

52 Triple-Digit Pitches: A Statcast-Era First

Misiorowski's 52 pitches at 100 mph or higher eclipses any previous single-game mark by a starting pitcher since Statcast's launch in 2008, as the report states. No other starter has recorded even 40 such pitches in a game, making Saturday's feat a significant outlier. The ace also finished with eight strikeouts and only one unearned run allowed, scattering four hits and three walks over seven innings.

The 103.7 mph Fastball That Rewrote History

The fastest pitch of the night—a 103.7 mph fastball—is the highest velocity recorded by a starting pitcher since tracking began, according to the source. While relievers have occasionally touched higher figures, Misiorowski's ability to sustain that kind of heat deep into a game is unprecedented for a starter. His season ERA now stands at 1.50, second in MLB only to Cristopher Sánchez of the Phillies.

Why Misiorowski Refused to Come Out in the Seventh

Misiorowski made it clear he did not want to be pulled in the seventh inning, even as Brewers manager Pat Murphy prepared to make a change, the report notes . The pitcher explained that he wanted to lessen the burden on a bullpen that has been heavily taxed and thinned by injuries.. By going deep into the game, he aimed to allow relievers to throw just one inning each, preserving their arms for the series ahead.

The Human Cost of Velocity: Hitting Tyler Freeman in the Head

The evening's drama was punctuated by a frightening moment in the sixth inning when Misiorowski struck Rockies hitter Tyler Freeman in the head with a 98 mph cutter. Freeman left the game but walked off the field without assistance, according to the report. Misiorowski was clearly troubled by the incident, and the episode raises ongoing questions about the risks pitchers take when throwing with maximum effort—and the ethical responsibility teams have to protect hitters from errant high-velocity pitches.

An ERA of 1.50 and a Bullpen in Need of Rest

Misiorowski's 1.50 ERA is remarkable, but it comes amid a team context where the bullpen has been stretched thin. He has allowed only one earned run over his last seven appearances and has thrown seven innings in four of his last five starts, per the report. Whether Milwaukee can sustain such a heavy workload on their ace without risking injury is an open question—especially as the season progresses and the physical toll of throwing 50+ triple-digit pitches per game accumulates.
