The young flamethrower’s electric stuff overwhelmed Cubs hitters and helped power Milwaukee to a convincing win, further cementing his status as one of baseball’s most exciting young arms in 2026.

Milwaukee Brewers right-hander Jacob Misiorowski turned heads across Major League Baseball when he unleashed a fastball clocked at 105.5 mph against the Chicago Cubs, a pitch that ranks among the fastest ever recorded in a game. The towering 6-foot-7 prospect’s overpowering velocity proved too much for Cubs hitters, who struggled to make contact all game long in Milwaukee’s decisive victory.

Quick Answer

Jacob Misiorowski threw a 105.5 mph fastball during a Milwaukee Brewers win over the Chicago Cubs, showcasing elite velocity that places him among the hardest-throwing pitchers in MLB history. The pitch, recorded by stadium radar, represents a new benchmark in Misiorowski’s still-developing career and signals Milwaukee’s investment in power pitching is paying dividends. Cubs batters were largely overmatched by his combination of extreme heat and secondary offerings throughout the contest.

What Is Misiorowski’s 105.5 MPH Pitch and Why It Matters

A 105.5 mph fastball is exceptionally rare at the Major League Baseball level. According to Statcast data, only a handful of pitchers in recorded history have consistently touched or exceeded the 105 mph threshold, including names like Aroldis Chapman, Jordan Hicks, and Hunter Greene. For Misiorowski to reach that velocity during a competitive game situation speaks to his elite arm talent and raw physical tools.

Research shows that pitches thrown at 105 mph or harder generate significantly higher whiff rates than standard fastballs. Hitters have approximately 100 milliseconds less reaction time compared to a 95 mph offering. This razor-thin window between recognition and swing decision makes 100+ mph fastballs among the most unhittable weapons in professional sports.

How Misiorowski’s Electric Performance Unfolded Against the Cubs

From the opening inning, Misiorowski established his fastball as the centerpiece of his arsenal against Chicago. The Cubs’ lineup, which entered the series averaging a respectable team OPS, struggled to square up his offerings consistently throughout the contest.

Dominant Strikeout Numbers Throughout the Game

Misiorowski racked up strikeouts at a prolific rate, challenging Cubs hitters with a fastball that sat in the upper 90s for most of his outing before he reached back for the 105.5 mph missile that electrified the stadium. His pitch mix kept hitters off balance, as even his secondary offerings looked faster by comparison after batters adjusted to the extreme velocity of his fastball.

Cubs Hitters Struggled to Make Solid Contact

Chicago’s batters managed only a handful of hard-hit balls against Misiorowski all game. The combination of his overwhelming velocity and deceptive delivery from his long frame created uncomfortable at-bats throughout. Many Cubs hitters appeared to be guessing between fastball and off-speed, often committing to swings well before the pitch reached the plate.

What Makes Jacob Misiorowski’s Arm So Special

The Milwaukee Brewers selected Misiorowski with the intent of developing a frontline starter, and the early returns suggest that plan is coming to fruition. His physical profile — standing 6-foot-7 with a long, loose arm action — gives him natural leverage that translates into elite velocity without the same mechanical stress many hard throwers endure.

Industry data indicates that pitchers with Misiorowski’s combination of height, extension, and velocity create a perceived velocity advantage. Because he releases the ball closer to home plate than shorter pitchers, his 105.5 mph fastball effectively arrives at the batter even faster than the radar gun reading suggests. Some analysts estimate his effective perceived velocity on that pitch exceeded 107 mph from the hitter’s perspective.

Historical Context: Where 105.5 MPH Ranks Among MLB’s Fastest Pitches

When Misiorowski’s 105.5 mph pitch is placed alongside MLB’s all-time velocity leaders, it firmly enters elite territory. Only a small number of pitchers have ever been recorded throwing harder in a Major League game.

Hardest Pitches Ever Recorded in MLB (Statcast Era, 2015-Present)

Pitcher	Top Velocity	Team	Season
Aroldis Chapman	105.8 mph	Cincinnati Reds	2016
Jordan Hicks	105.4 mph	St. Louis Cardinals	2019
Jacob Misiorowski	105.5 mph	Milwaukee Brewers	2026
Aroldis Chapman	105.1 mph	New York Yankees	2018
Hunter Greene	104.9 mph	Cincinnati Reds	2022
Ben Joyce	104.8 mph	Los Angeles Angels	2024

Misiorowski’s 105.5 mph reading places his pitch among the three hardest ever tracked by Statcast technology. That distinction alone underscores just how remarkable his arm talent is, particularly for a pitcher who is still refining his command and secondary offerings.

Why the Brewers’ Pitching Development Is Paying Off

Milwaukee has long been recognized as one of the best organizations at developing pitchers, and Misiorowski represents the latest success story in that tradition. The Brewers’ pitching development infrastructure — led by their analytics and coaching staff — has focused on maximizing velocity while maintaining enough command to survive at the MLB level.

According to team insiders, Misiorowski has added approximately 2-3 mph to his fastball since being drafted, a testament to the organization’s strength and conditioning program. The Brewers have also worked with him to improve his pitch tunneling and sequencing, ensuring that his elite velocity translates into actual outs rather than just impressive radar gun readings.

How does Misiorowski’s 105.5 mph pitch compare to the fastest pitch ever thrown in MLB?

The fastest pitch ever recorded in MLB belongs to Aroldis Chapman, whose 105.8 mph fastball was tracked by Statcast in 2016. Misiorowski’s 105.5 mph offering places him in the top three hardest pitches ever recorded, making it an exceptionally rare feat that only a few pitchers in history have achieved.

Who is Jacob Misiorowski and what team does he play for?

Jacob Misiorowski is a right-handed pitcher for the Milwaukee Brewers who stands 6-foot-7 and is known for his elite fastball velocity. The Brewers developed him through their farm system, and he has quickly become one of the most talked-about young pitchers in baseball due to his ability to consistently throw above 100 mph in game situations.

Why is it so hard to hit a 105.5 mph fastball?

Hitting a 105.5 mph fastball is extraordinarily difficult because the ball reaches home plate in approximately 325 milliseconds, giving hitters roughly 250 milliseconds to decide whether to swing — about the minimum reaction time the human brain requires for visual-motor tasks.
