MILWAUKEE — Milwaukee Brewers right-hander Jacob Misiorowski isn’t content with merely being the game’s hardest-throwing starting pitcher.
He’s intent on becoming the best. He already may be there.
The 24-year-old is hitting unprecedented velocities for a starter in MLB’s pitch-tracking era that began in 2008. Over the last month, he’s dominated unlike any pitcher in the last century.
Misiorowski has allowed just one run over his last eight starts heading into his matchup with the Atlanta Braves. He says he can’t come up with a specific moment or decision that sparked this surge.
“It’s more that it finally clicked,” said Misiorowski, who is 8-2 with a 1.34 ERA and 131 strikeouts to lead the majors in the latter two categories. “Everything started settling in and feeling good.”
The fact Misiorowski used the word “finally” to describe an emergence in his first full major league season underscores his exacting standards.
Misiorowski’s rise has Brewers manager Pat Murphy comparing him to Forrest Gump, which prompted a social media post by the pitcher his own face over the Tom Hanks movie character’s body.
“It’s for sure meant to be a compliment for a guy who didn’t put in limits on himself and his naiveté,” Murphy said. “It was a factor in a positive way, where he went out and achieved whatever he set his mind to, and didn’t let the outside forces, weren’t even aware of the outside forces, and didn’t let anything hold him back.”
Misiorowski was selected to the All-Star Game last season after only five starts. He struggled late last year before producing a 1.50 postseason ERA during Milwaukee’s run to the NL Championship Series. Now he’s a Cy Young Award favorite.
Misiorowski is more than just a hard thrower
The eye-popping numbers most associated with Misiorowski come from the radar gun. He reached 104.5 mph — the fastest velocity by any starter in the pitch tracking era — and got to 100 mph on a record 58 pitches during the Brewers’ 6-0 victory over the Philadelphia Phillies.
He’s thrown 460 pitches at least 100 mph this season, already surpassing the record for a starter set by Cincinnati’s Hunter Greene with 337 such pitches in 2022.
But his most impressive statistics have more to do with results than velocity.
According to MLB.com, Misiorowski’s 0.17 ERA since May 1 is the best in an eight-start stretch for any pitcher since earned runs became an official statistic in 1913. Against Philadelphia, he became the third pitcher since 1900 to throw a shutout while striking out 15 and allowing no more than one baserunner.
Opponents are batting just .140 against Misiorowski this season. SportRadar says no starting pitcher has allowed an opponent batting average of .166 or below over a full non-pandemic season since at least 1910. Boston’s Pedro Martinez had batters hitting .167 against him in 2000. Opponents hit .168 against Cleveland’s Luis Tiant in 1968.
Misiorowski’s development into a complete pitcher should come as no surprise, considering who he grew up watching.
The pitchers Miz admires most aren’t necessarily smoke throwers
The list of pitchers he admired growing up includes Adam Wainwright, Zack Greinke, Clayton Kershaw and Chris Sale. While Sale is a hard thrower and Kershaw also had outstanding velocity early in his career, Wainwright and Greinke succeeded without overpowering fastballs.
They had one thing in common.
“Every game, you felt like they could trust them to get a win,” Misiorowski said. “That was the big thing. You looked at those guys and they were going out there and going to perform for seven or eight innings to secure the team a win.”
His appreciation for baseball history includes a baseball card collection he says numbers in the thousands, though he probably owns even more Pokemon cards.
“Since I was a kid, my dad got me into it,” Misiorowski said of his baseball card collection. “It’s huge right now. I think I need to downsize it a little bit, but it’s fun.”
His enthusiasm shows on the mound and in his work ethic. He devoted the offseason to upgrading his leg strength to withstand the rigors of a full season and results are showing in his improved endurance and command.
“He could rest on his laurels. ‘Hey, I was an All-Star in my first year. I pitched in the playoffs. I pitched well. I can do it. I’m fine. I’ll be all right,’“ Murphy said. “Or you can say, ‘I’m going home. I’m going to get stronger. I’m going to do whatever I can do to come back and dominate.’ That’s what he’s done.”
He’s stabilizing an injury-riddled rotation
Misiorowski’s growth has helped the Brewers overcome numerous pitching injuries to build a comfortable NL Central lead. With Misiorowski and Kyle Harrison (8-1, 2.47) leading the rotation, the Brewers rank fourth in the majors in ERA.
Over his last eight starts, Misiorowski has struck out 80 while allowing nine walks and 14 hits over 54 1/3 innings. The only extra-base hit he’s allowed over his last nine starts was a double by Houston’s Isaac Paredes on May 31.
The low walk totals are notable after Misiorowski battled control issues as a rookie. He walked 31 batters in 66 innings last year, but now constantly gets ahead of hitters.
“He’s winning the 0-0 and the 1-1 (counts) a lot,” pitching coach Chris Hook said. “When he doesn’t, it stands out to be like, ‘Oh, God, he didn’t win the 0-0. He didn’t win the 1-1.’ Like that’s weird, for him to go to a two-ball count.”
Once hitters fall behind in the count, they have little chance.
After facing him for the first time last month, New York Yankees slugger and three-time MVP Aaron Judge noted that “he’s almost basically releasing it in the catcher’s glove” due to the extension Misiorowski gets with his 6-foot-7 frame.
MLB Network analyst and two-time All-Star pitcher Ryan Dempster says Misiorowski reminds him of 6-10 Hall of Fame lefty Randy Johnson in that regard because their hands seem right in front of the plate to the batter when they let go of the ball.
“You can tell yourself to swing, but your brain doesn’t quite compute until it’s out of the hand,” Dempster said. “By the time it’s out of his hand, it’s already on you. I haven’t seen a fastball like this since Kerry Wood.”
Wood’s career was derailed by injuries, leading to worries of hard throwers being susceptible to blowing out pitching arms. Dempster notes Misiorowski is playing in an era with lower pitch counts. Misiorowski also produces elite velocity without overthrowing.
“He sure is repeating his delivery, and when you repeat your delivery, you tend to stay healthy,” Dempster said. “Guys who don’t repeat deliveries and get out of whack and something’s a little off, they struggle with that. I really think he will stay healthy, just me personally.”
