On a Friday night in Milwaukee that was already marked for ceremony, Jacob Misiorowski turned a baseball game into a physics demonstration. The 24-year-old right-hander threw 10 pitches at or above 103 mph against the New York Yankees on May 8, 2026 — a number that had never been reached by any starting pitcher in the Statcast era. He topped out at 103.6 mph, the hardest pitch ever recorded from a starter since MLB began tracking velocity in 2008. When the night ended, the Brewers had a 6-0 shutout, and baseball had a new benchmark for what a starting pitcher's arm is capable of.
The Brewers-Yankees series continues this weekend at American Family Field, with Game 2 underway Saturday and Game 3 scheduled for Sunday. But the story everyone is talking about is what happened Friday — and why it matters far beyond a regular-season series in May.
The Historic Performance: What Misiorowski Actually Did
To appreciate the magnitude of Friday's outing, start with the raw count. Misiorowski made MLB history by throwing 10 pitches at 103 mph or harder in a single game — something no starting pitcher had ever done. Three of those pitches hit 103.6 mph, the new Statcast-era ceiling for starters.
Before Friday night, MLB starting pitchers had combined for just three pitches at or above 103 mph across the entire Statcast era — spanning nearly two decades of data. Misiorowski threw that many in a single at-bat. In six innings and 95 pitches (66 strikes), he struck out 11 Yankees and did not allow a run. The previous fastest pitch by a starter in Statcast history was 103.2 mph, thrown by Jordan Hicks on July 12, 2022. That record lasted less than four years before Misiorowski erased it.
According to The Athletic's game report, Misiorowski now owns 11 of the 14 fastest pitches ever thrown by a starting pitcher in the Statcast era. He doesn't just hold the record — he is the record. The leaderboard for this category is essentially his personal highlight reel.
Putting the Velocity in Context
Velocity records in baseball carry an asterisk that matters: relievers and starters operate under completely different physical demands. A closer throwing a single inning can grip and rip without pacing himself. A starter must manage 90-plus pitches across six or seven innings, protect his arm across a five-day rotation, and sustain effectiveness into later innings when hitters have seen the pitch twice.
This is why Misiorowski's performance is genuinely unprecedented. Chapman, Betances, and other relief fireballers have thrown harder than most starters, but they were never asked to do it for six innings. What Misiorowski is doing rewrites the assumption that 100+ mph gas is a reliever's domain. He's doing it as a starter, repeatedly, in his prime developmental years.
The comp that keeps surfacing is Nolan Ryan — not because their styles are identical, but because Ryan was also a pitcher who made scouts and hitters rethink what was physically possible for a starting arm. Ryan threw harder for longer than anyone thought sustainable. Misiorowski is doing something similar at an era when Statcast removes all doubt about the numbers.
MLB starting pitchers had combined for only three pitches of at least 103 mph in the entire Statcast era before Misiorowski's Friday outing. He threw that many in a matter of minutes.
Who Is Jacob Misiorowski?
Misiorowski entered the 2026 season as a prospect who had generated buzz, but Friday was the night he crossed from "interesting arm" to "historical figure." He leads all of Major League Baseball with 70 strikeouts on the season and holds a 2.45 ERA across 44 innings — numbers that would make him a Cy Young contender if sustained.
His previous start, on May 1 against the Washington Nationals, already showed what he was capable of: he threw 43 pitches at 100 mph or harder across 5⅓ shutout innings in a 6-1 Brewers win, before leaving with a right hamstring cramp. That raised legitimate durability questions heading into Friday's start. The hamstring concern appears to have been resolved, and against the Yankees he not only returned to form but exceeded anything he'd done before.
The hamstring scare is worth tracking. Misiorowski's value to Milwaukee — and the historic record he's building — depends on staying healthy through a full rotation. Pitchers who throw at this velocity are rare; pitchers who do it as starters are almost nonexistent. The Brewers' medical and pitching staff will be managing him carefully for exactly that reason.
The Full Picture: Brewers-Yankees Series Update
The series at American Family Field spans three games, with Friday's shutout as the opener. Game 2 on Saturday features Kyle Harrison on the mound for Milwaukee against Cam Schlittler for New York. Paul Goldschmidt has already made his mark on the series, hitting a home run Saturday — his 21st career homer at American Family Field in 69 games there, a remarkable venue-specific record for a player who spent his career elsewhere before joining New York.
Game 3 is scheduled for Sunday, May 10, with Logan Henderson starting for Milwaukee against Carlos Rodón, who will be making his season debut for the Yankees. Rodón's first appearance of the year against a Brewers lineup that just watched Misiorowski dominate will be its own storyline.
The Brewers enter the series at 20-16, competitive in the NL Central but not yet pulling away from the pack. A sweep of a marquee opponent like the Yankees — who carry one of baseball's largest payrolls and perennial postseason expectations — would be a significant statement for Milwaukee's postseason credentials.
There was also a concerning injury note from Friday's game: outfielder Brandon Lockridge was placed on the 10-day injured list with a right knee laceration and contusion after colliding with exposed concrete along the left-field wall. The Brewers' manager shared an update on Lockridge's condition, and Blake Perkins was recalled from Class AAA Nashville to fill the roster spot. The collision was a reminder of how quickly a celebratory night can turn anxious — and of the ongoing conversation about stadium infrastructure and player safety.
A Night With Two Stories: CC Sabathia's Wall of Honor Induction
Friday's game carried ceremony beyond the box score. CC Sabathia — the Hall of Fame left-hander who began his career in Milwaukee before a decorated run with the Yankees — was inducted into the Brewers' Wall of Honor before the game. It was a pointed piece of symmetry: Sabathia honored by his original franchise on the same night his former franchise was being shut out by an arm that's redefining what starting pitchers can do.
Sabathia's induction also served as context for how far the Brewers have come as an organization. When Sabathia was in Milwaukee in the early 2000s, the franchise was building toward respectability. The current version of the club — which developed Misiorowski through its system — is one that produces historic pitching talent and competes in October. That arc from Sabathia's departure to Misiorowski's arrival represents two decades of organizational evolution.
What This Means for Baseball's Velocity Era
The sport has been in a velocity arms race for over a decade, driven by analytics, biomechanics research, and a deeper understanding of how to develop pitching. Triple-digit fastballs, once reserved for the most elite relievers, have become common enough that 100 mph is no longer automatically a conversation-stopper in a bullpen.
But 103+ mph, sustained across six innings by a starter, is something different. It suggests either that the ceiling on human arm speed is higher than we thought — or that Misiorowski is a rare outlier who will force baseball people to recalibrate their assumptions about what's possible.
The more interesting question isn't whether he's fast. It's whether he can stay fast. Pitchers who throw this hard often face injury risk, shortened careers, or mandatory conversion to the bullpen when their bodies can't sustain the workload. Misiorowski's hamstring cramp on May 1 is a data point, not a death knell. But it's a reminder that the most exciting arm in baseball is also operating at the edge of physical sustainability.
If he stays healthy and this is a season-long performance rather than a two-start burst, the Cy Young conversation will start immediately. If he struggles with durability, Milwaukee will face the classic developmental dilemma: protect the asset by limiting his innings, or let him pitch through it and risk a more serious injury.
For fans watching the Yankees-Brewers series this weekend, the backdrop to every pitch is that awareness — this might be a once-in-a-generation arm, and every start is something worth watching.
Analysis: Why Misiorowski's Performance Is More Than a Stat Line
Records in baseball are abundant. Someone leads the league in something every week, and most records are forgotten by the following season. What makes Misiorowski's Friday performance different is that it redraws a category boundary rather than simply moving the marker inside an existing one.
The dividing line between starting pitcher velocity and relief pitcher velocity has functioned as a kind of physical law — not a rule, but an observed constraint based on what human bodies can sustain across extended outings. Misiorowski is breaking that constraint in real time, in front of Statcast cameras that remove all ambiguity about what's happening.
The Yankees, for their part, were not a weak opponent. New York carries a lineup built for October, and getting shut out 6-0 while a 24-year-old throws 103.6 mph past your hitters is a legitimate humiliation. That the game happened to coincide with CC Sabathia's Wall of Honor ceremony — a player who left Milwaukee for New York and became a legend — gave the evening a narrative weight that felt almost scripted.
The Brewers are not a franchise that usually generates this kind of national conversation. Milwaukee is a mid-market club that has punched above its weight through development, not spending. Misiorowski is the clearest example yet of that philosophy producing something exceptional. If he holds up, he's not just a Brewers story — he's a baseball story.
Frequently Asked Questions

103.6 mph, thrown by Jacob Misiorowski of the Milwaukee Brewers on May 8, 2026, against the New York Yankees. The previous record was 103.2 mph, set by Jordan Hicks on July 12, 2022.
How many pitches did Misiorowski throw at 103 mph or above on Friday?
Ten pitches at or above 103 mph in a single game — a Statcast-era record for a starting pitcher. Before Friday, MLB starters had collectively thrown only three such pitches in the entire Statcast era (since 2008).
What are Misiorowski's stats for the 2026 season?
He leads the majors with 70 strikeouts, holds a 2.45 ERA across 44 innings, and has now established himself as one of the most dominant starting pitchers in baseball through the first two months of the season.
Who are the Yankees and Brewers starting in Game 3?
Logan Henderson starts for Milwaukee on Sunday, May 10. The Yankees will send Carlos Rodón to the mound — his first start of the 2026 season after returning from an absence.
Was anyone injured in the Yankees-Brewers series?
Yes. Brewers outfielder Brandon Lockridge suffered a right knee laceration and contusion after colliding with exposed concrete along the left-field wall during the May 8 game. He was placed on the 10-day injured list, and Blake Perkins was recalled from Triple-A Nashville to take his roster spot.
Conclusion
Jacob Misiorowski's Friday night in Milwaukee wasn't just a dominant start. It was a line drawn in the record books — 103.6 mph, thrown as a starter, 10 times over 103, in a 6-0 shutout of one of baseball's most recognized franchises. Whether this is the opening chapter of a historic career or a peak we'll reference years from now as a cautionary tale about velocity and durability, it deserves to be seen for what it is: one of the most remarkable individual pitching performances in the sport's modern statistical history.
The series continues. The Yankees will try to answer. And somewhere in the mix of Rodón's season debut, Goldschmidt's homers, and the ongoing math of the NL Central race, Misiorowski's arm remains the story no one can look away from.
