Milwaukee Brewers right-hander Jacob Misiorowski has emerged as Major League Baseball’s most dominant pitcher in 2026.

His performance validates this assessment emphatically. Following a complete-game one-hitter against the Philadelphia Phillies on June 12, Misiorowski lowered his season Earned Run Average to 1.34 across 87 innings pitched.

Entering his next start in Atlanta against the Braves on June 19, Misiorowski carries an impressive 8-2 record with a WHIP of 0.73. His 13.6 strikeouts per nine innings represent elite-level dominance.

Dubbed “The Miz” by teammates and fans, the 6-foot-7, 201-pound pitcher relies on a downhill delivery that generates phenomenal velocity. His fastball reaching 104.5 mph creates an almost supernatural challenge for hitters.

Dominance On The Mound

Misiorowski’s repertoire includes a four-seam fastball (thrown 68% of the time), curveball, cutter, and changeup. In his masterful performance against Philadelphia, he faced the minimum 27 batters, yielding only a fourth-inning single to Kyle Schwarber that was erased on a double play.

He accomplished this while throwing just 95 pitches—averaging only 10.55 per inning. Over eight consecutive starts, his ERA sits at an extraordinary 0.17, with 80 strikeouts and a single extra-base hit allowed.

“He did this in the midst of a stretch of eight starts in which his ERA has been .017, he’s struck out 80 and allowed just a single extra base hit,” noted MLB.com.

The numbers speak volumes: imagine facing a 104.5 mph fastball repeatedly, with no time to adjust between pitches.

Historical Context Among Elite Velocity

The Atlanta Journal-Constitution’s list of fastest pitches since July reveals Aroldis Chapman’s dominance in 2010, 2016, and 2016 (multiple entries at 105.8, 105.7, 105.4, 105.2, 105.1 mph). Jordan Hicks also joins the list at 105 mph in 2018.

In 2026, however, Misiorowski has matched Chapman’s peak velocity twice—reaching 104.5 mph. While the season remains early, his consistent elite velocity positions him as a legitimate successor to baseball’s velocity throne.

Legends Of The Past

Cleveland Indians legend Bob Feller, nicknamed “Rapid Robert,” was renowned for his blazing fastball in the pre-radar gun era. Estimated at nearly 98 mph, Feller once raced against a speeding motorcycle.

As documented on halmccoy.com: “They would time Feller’s fastball against a speeding motorcycle. As the motorcycle sped past him, Feller had to unleash his fastball and hit a small paper target at home plate. Second after the motorcycle roared past, Feller fired his heater. Feller’s pitch quickly outraced the motorcycle, ahead by a good three feet when it split the paper bull’s-eye target.”

Today’s technology captures Misiorowski’s velocity with precision—104.5 mph consistently. The comparison invites speculation: could “The Miz” meet that vintage challenge?

Looking Ahead

The Milwaukee Brewers boast an intriguing blend of veteran experience and emerging talent. “The Miz” has unequivocally disrupted baseball’s pitching landscape.

Misiorowski’s fastball sits at 104.5 mph—delivered for strikes with devastating effectiveness. Simply put, hitting his heater represents the premier pitch in baseball.

While Shohei Ohtani has encountered recent setbacks and Christopher Sanchez struggled in his last outing, Misiorowski’s consistency has been extraordinary. Tarik Skubal and Yoshinobu Yamamoto deserve recognition, but for this observer, Misiorowski stands as the current ace of professional baseball.

His impact extends beyond this season—Misiorowski appears poised to maintain dominance well into the future.
