Across baseball, few pitchers enjoyed a more dominant month than Jacob Misiorowski of the Milwaukee Brewers and Cristopher Sánchez of the Philadelphia Phillies. Misiorowski was nearly untouchable, posting a 0.23 ERA, .109 opponent batting average, and 0.52 WHIP while striking out 57 batters. Along the way, he set multiple monthly franchise records and held opponents to a .101 slugging percentage, the lowest mark ever recorded in MLB history.
Sánchez was equally impressive in his own right, not allowing a single run across 39 innings, and continuing a 44.2 scoreless innings streak that dates back to April. What these two starters accomplished over the past month was nothing short of surreal.
Perhaps lost amid the attention surrounding Misiorowski's historic month is just how dominant the rest of Milwaukee's starting rotation was. While Misiorowski certainly led the charge, Kyle Harrison was outstanding in his own right, posting a 0.96 ERA over five starts. Harrison continued his strong stretch with a 12-strikeout gem in his first start of June last night, though his 23-inning scoreless streak did come to an end at the hands of Willy Adames, who hit a solo shot in Harrison's penultimate at-bat of the game.
Meanwhile, Logan Henderson continued his breakout campaign with a 2.14 ERA, 0.95 WHIP, and .197 opponents' batting average in four starts during the month of May before he landed on the IL with a lower back injury. Coleman Crow also appeared in the Brewers' rotation in May and posted a 3.00 ERA in nine innings pitched across two starts.
Other pitchers to make starts during the month included Brandon Sproat, Chad Patrick, and Robert Gasser. Together, this deep and talented group helped Milwaukee assemble the most effective rotation in baseball during May, leading all of MLB with a 2.48 ERA while also out-pacing all teams with 4.6 fWAR. For context, Tampa Bay Rays' rotation finished in second place in regard to ERA with a 2.66 mark and the Philadelphia Phillies were the runner-ups in regard to fWAR with 3.9.
However, what is most impressive about the Brewers' group of May starters is the success despite their inexperience. With Brandon Woodruff on the IL, every single starter who threw for the Brewers in the month of May has less than two years of MLB service time.
Brewers' starting rotation's unparalleled success in May made more impressive by group's inexperience
The Brewers knew their rotation heading into the 2026 campaign was going to lack experience. Even Quinn Priester, who was slated to be a key piece of Milwaukee's starting staff before landing on the IL in Spring Training due to a thoracic outlet syndrome-related injury, has less than two years of major league service time to his name.
Milwaukee was betting heavily on Misiorowski's ability to become a bona fide ace less than a year into his major league tenure, which he's done so and then some through the first two months of the season. However, they were also betting that Harrison and Sproat would immediately be able to jump into consistent rotation roles despite neither of them being mainstays in a big-league rotation up to this point. While Sproat continues to develop under the guidance of the Brewers' excellent pitching coach staff, Harrison already looks like a big-league veteran.
However, the gamble didn't stop there. Milwaukee needed several of Patrick, Henderson, Gasser, and Crow to step up and be productive arms very early in their careers. Patrick held down a starting role for the first month of the season before becoming one of Milwaukee's more valuable relief arms, and Henderson and Crow have filled in admirably in the absence of Woodruff and Priester. Gasser has had a rocky first two starts of the season, but hope remains high that he will be able to regain his form and be an important part of the rotation before the season is over.
Overall, the way that Milwaukee's pitching staff is currently performing despite each of them still being in the very early parts of their careers is simply incredible. Plenty of credit certainly goes to Chris Hook and Jim Henderson, but this type of success requires excellence and buy-in from all parties involved. With each of these arms under team control for many years to come, it's exciting to think about what the Brewers' starting staff will look like over the next half decade.
