Jacob Misiorowski Uncorks a 105.5 MPH Bullet to Secure Brewers Win

Jacob Misiorowski threw a 105.5 mph fastball past a Cubs hitter to help the Milwaukee Brewers secure a victory in late June 2026. The blistering pitch, tracked by MLB’s Statcast system, stands as one of the hardest thrown pitches in the 2026 season and cements Misiorowski’s status as the hardest-throwing active pitcher in Major League Baseball.

Quick Answer

Brewers right-hander Jacob Misiorowski recorded a pitch clocked at exactly 105.5 mph during Milwaukee’s win over the Chicago Cubs in late June 2026. The fastball surpassed every pitch thrown by any MLB pitcher this season, and it places Misiorowski in rare historical company alongside Aroldis Chapman and Jordan Hicks on the all-time Statcast velocity leaderboard. According to ESPN’s reporting, the pitch came during a key at-bat and helped Misiorowski shut down Chicago’s lineup.

How Fast Is a 105.5 MPH Pitch in MLB History?

A 105.5 mph fastball is exceptionally rare in professional baseball. Since Statcast began tracking pitch velocity in 2008, only a handful of pitchers have ever recorded a pitch at 105 mph or higher. The most famous name on that list is Aroldis Chapman, who threw the hardest tracked pitch in MLB history at 105.8 mph in 2010. Jordan Hicks and a small number of other fireballers have also crossed the 105 mph threshold, but no pitcher has sustained that level of velocity as a regular starter.

Misiorowski’s 105.5 mph bullet places him in the top tier of all-time hardest pitches ever thrown in a Major League game. Unlike relievers who throw maximum effort for a single inning, Misiorowski has demonstrated this kind of velocity while working as a starting pitcher for Milwaukee, which makes the feat even more remarkable.

Fastest Pitches in Statcast History (2008-2026)

Pitcher	Velocity	Year	Team
Aroldis Chapman	105.8 mph	2010	Cincinnati Reds
Aroldis Chapman	105.7 mph	2012	Cincinnati Reds
Jacob Misiorowski	105.5 mph	2026	Milwaukee Brewers
Jordan Hicks	105.3 mph	2019	St. Louis Cardinals
Aroldis Chapman	105.1 mph	2016	New York Yankees

What Makes Misiorowski’s Velocity So Unusual?

Most pitchers who throw above 104 mph are bullpen arms who max out for one inning at a time. Relievers like Aroldis Chapman and Jordan Hicks built their careers around short, high-effort outings where they could empty the tank on every pitch. Jacob Misiorowski is different because he generates elite velocity as a starting pitcher, throwing deep into games while maintaining speeds that rival the hardest-throwing relievers in baseball.

According to industry data, the average MLB fastball in 2026 sits around 93.8 mph. Misiorowski’s hardest pitch exceeded that average by nearly 12 mph, a staggering differential that leaves hitters with an almost impossibly small reaction window. A pitch thrown at 105.5 mph travels from the mound to home plate in approximately 0.375 seconds, giving a batter roughly 125 to 150 milliseconds to identify the pitch type, decide whether to swing, and begin their motion.

How Did Misiorowski Perform in the Brewers Win Over the Cubs?

Misiorowski delivered a dominant outing against the Chicago Cubs on June 26, 2026, guiding the Brewers to a victory at American Family Field. The right-hander consistently overwhelmed Chicago’s hitters with his elite fastball velocity and complemented it with sharp breaking stuff that kept the Cubs off balance throughout the game.

The 105.5 mph fastball came at a crucial moment during the game, freezing a Cubs hitter who was unable to catch up to the pitch. According to ESPN’s game recap, the pitch drew an audible reaction from the crowd and the broadcast booth alike. Brewers manager Pat Murphy has repeatedly praised Misiorowski’s ability to maintain his velocity deep into outings, a trait that separates him from other hard throwers in the sport.

Jacob Misiorowski’s 2026 Season Stats and Development

Jacob Misiorowski has taken a significant step forward in the 2026 MLB season. The young right-hander, who was selected by the Brewers in the 2021 MLB Draft, has developed into one of the most feared pitchers in the National League. His combination of triple-digit velocity and improving command has made Milwaukee’s rotation one of the deepest in baseball.

Key Performance Indicators for Misiorowski in 2026

• Average fastball velocity: Consistently in the upper 90s, touching 103-105 mph regularly
• Strikeout rate: Among the highest in the NL for starting pitchers
• Whiff rate: Batters consistently chase and miss against his fastball and slider combination
• Deep outings: Able to pitch into the sixth and seventh innings while maintaining velocity

Research shows that pitchers who can throw above 100 mph with consistency have a significantly higher strikeout rate than the league average. Misiorowski’s ability to do this while starting games places him in historically elite territory. His development from a raw, hard-throwing prospect into a polished MLB starter represents one of the best pitching development stories in recent Milwaukee Brewers history.

Why the Brewers’ Investment in Misiorowski Is Paying Off

The Milwaukee Brewers drafted Misiorowski knowing that his raw arm talent was among the best in his draft class. The organization invested significant resources in his development, working with pitching coaches to refine his mechanics and add secondary pitches that would allow him to succeed as a starter rather than a reliever. That investment is paying dividends in 2026 as Misiorowski anchors a Brewers rotation with legitimate postseason aspirations.

The Brewers have built their franchise around player development and smart roster construction under general manager Matt Arnold. Misiorowski’s emergence as a frontline starter validates Milwaukee’s approach of identifying high-ceiling arms and investing in long-term development. For a mid-market franchise competing against larger-payroll teams, having a homegrown ace on a controlled salary is an enormous competitive advantage.

What Does a 105.5 MPH Pitch Mean for Hitters?

Hitting a 105.5 mph fastball is one of the most difficult tasks in professional sports. MLB hitters typically begin their swing decision within 150 milliseconds of the ball leaving the pitcher’s hand. At 105.5 mph, the ball reaches home plate in roughly 375 milliseconds total, leaving almost no margin for error. Research from the California Institute of Technology has shown that at speeds above 100 mph, even elite hitters struggle to make solid contact consistently.

When Misiorowski pairs that velocity with his slider and changeup, hitters face a compounded problem. They must gear up for a pitch that arrives 5 to 7 mph faster than they expect, while also remaining ready to adjust to pitches that move in different directions at different speeds. This combination of velocity and pitch variety is what transforms a hard thrower into a genuinely dominant pitcher.
