Jacob Misiorowski turned the 2026 regular season into a statistical runaway, and the hitters who had to stand in against him describe the experience in terms that rarely apply to any pitcher. The Brewers right-hander led MLB in ERA (1.80), strikeouts (252), strikeout rate (37.9%) and WHIP (0.80). Opponents batted .157 against him, the lowest mark ever for a qualified starter. He is expected to win the NL Cy Young Award and will start Game 1 of the NLDS against the Padres on Saturday at 8:30 p.m. ET on FS1.
The velocity is only part of the problem
Misiorowski had the hardest average fastball among MLB starting pitchers and reached 105.5 mph at his peak. He hit 103 mph or harder 136 times in the regular season. Jordan Hicks had reached 103 mph twice in 2022. Of the 369 instances of a starting pitcher hitting 102 mph this season, 365 belonged to Misiorowski. He threw 22 pitches at 104 mph or faster. Only three other pitchers exceeded 104 mph at all: Ben Joyce, Edgardo Henriquez and Mason Miller.
That gap helps explain why hitters sound almost resigned. Bo Bichette said Misiorowski has the best fastball in the game and, crucially, throws strikes. Pedro Pagés offered the bluntest advice: swing and pray, stay short and early. Pagés said the fastball is different because of the velocity, the size of the pitcher and the extension.
Extension changes the math
The 6-foot-7 Misiorowski averaged 7.6 feet of extension, the farthest among starters. Dylan Cease ranked second in strikeout rate among starters, yet Misiorowski’s extension was more than a foot farther. The result is that his pitches arrive from closer than the standard 60 feet, 6 inches.
Zach Neto said the extension makes the fastball play higher. Royce Lewis put a number on it: extension cuts the distance, making 103 mph look like 112. Lewis, who had faced 17 pitchers who threw 100 mph or faster, called Misiorowski one of a kind and a unicorn.
Movement and reverse splits
Velocity alone would be enough. Misiorowski’s four-seamer also averaged 11.2 inches of arm-side run, ranking 18th among right-handers with at least 500 fastballs. Wade Meckler said that run creates an optical illusion for left-handed hitters. Meckler also said Misiorowski’s fastball is the best he has seen and that hitters must look fastball against him.
The numbers back up the discomfort on both sides of the plate. Misiorowski had reverse splits in 2026: lefties managed a .378 OPS, righties .582. Left-handed hitters typically hold the advantage against right-handed pitching, but Misiorowski inverted that relationship.
How hitters tried to adjust
Kyle Karros said hitters cannot match power with power against Misiorowski. Karros said his hits came to the middle or opposite field. Jake McCarthy said angle and other elements matter beyond velocity. Meckler, after seeing a cutter once, adjusted to it. That cutter was the pitch Meckler hit for a 388-foot home run, one of his three regular-season homers, though he noted the cutter was a different look from the fastball.
Bryce Harper went 0-for-3 against Misiorowski in 2026, a year after homering off him in 2025. Harper said he tries to be on time and called Misiorowski’s stuff incredible, with one of the best heaters in the game. Harper said he does not see the success going away.
The season in miniature
The game logs show how little hitters could do even when they had a plan. On May 25, Misiorowski struck out 12 Cardinals in seven innings; Pagés was one of two St. Louis hitters with a hit. Against the Rockies, he struck out eight in seven innings while allowing one unearned run. In a later start against Colorado, he struck out 12 in five innings, allowed one run and threw 80% four-seamers with no sliders. In that game he threw six straight four-seamers over 103 mph to McCarthy.
Against the Angels, he struck out 10 and allowed two runs in seven innings. Los Angeles handed him one of his five losses. Meckler hit his 388-foot homer off a 95.5 mph cutter in that matchup.
Misiorowski allowed 14 home runs in 2026. He lost five games. That is the entire list of what went wrong. In 2025, he threw a 15-strikeout complete-game shutout on 95 pitches against the Phillies. Now the Padres get the first look at him in the postseason, and hitters around the league already know what that means: a fastball that plays faster than its radar reading, from a release point that shortens the field.
