Jacob Misiorowski has been nothing short of extraordinary for the Milwaukee Brewers in 2026. The 24-year-old right-hander has compiled one of the most dominant regular seasons any pitcher has produced in recent memory — a 0.79 WHIP, 227 strikeouts across 155 innings and a .154 batting average allowed that makes opposing hitters look overmatched.
But as October approaches, a question looms: Can the Brewers keep him fresh for the postseason?
That concern became sharper Wednesday night at Wrigley Field. Against the Chicago Cubs, Misiorowski departed after just four innings, having surrendered five runs on five hits and four walks. Over his last four starts, the otherworldly consistency that defined his season has shown small cracks.
The culprit is straightforward: Misiorowski is accumulating innings at a historically heavy rate. He threw 129.1 innings between the minors and majors in 2025. With the Brewers already clinching the top overall seed and a postseason berth well before October, Misiorowski could eclipse 180 innings for the calendar year with just four more regular-season starts remaining.
Jake Peavy, the former Padres ace and Cy Young Award winner, recently addressed the issue directly. "Once I started leaking oil, it was hard for me to even take a week or two off and get what I had back," Peavy said. His prescription is clear — the Brewers should consider skipping Misiorowski a start or two, allowing him to enter October with restored freshness rather than accumulated fatigue.
This isn't theoretical hand-wringing. Studies on pitcher health consistently show that workload management — particularly in the latter stages of a season — correlates with postseason performance and reduced injury risk.
The Brewers' situation presents a classic management dilemma with no perfect solution. Keeping Misiorowski in his regular routine minimizes disruption to rhythm and mechanics. Pitchers are creatures of habit; changing their schedule can sometimes backfire psychologically or technically. On the other hand, a fresh Misiorowski in a Game 1 of the National League Championship Series could be the difference between an extended playoff run and an early exit.
Milwaukee's supporting cast is legitimate. Jackson Chourio has emerged as a star outfielder, Brice Turang provides defensive brilliance and consistent contact, William Contreras offers power and defensive prowess behind the plate, and Andrew Vaughn continues to produce. The rotation has depth with Kyle Harrison and Logan Henderson as formidable second and third options.
Yet none of that fundamentally changes the equation. In a best-of-seven series, a fresh, fully available ace matters disproportionately. The Dodgers last year understood this when they managed Yoshinobu Yamamoto's workload heading into October, then deployed him as a crucial weapon in their World Series run.
What makes this decision genuinely difficult is that Misiorowski himself likely has opinions about his own body and readiness. A 24-year-old in the midst of a career-defining season might legitimately believe he can manage the workload. Those instincts deserve respect — but they shouldn't be the only voice in the conversation.
The Brewers' medical and coaching staff should be running the numbers. How much does rest improve postseason performance metrics? What does the literature on pitcher durability suggest about the threshold between preparation and overtaxing?
For now, Milwaukee has the luxury of time. The regular season provides a window to experiment, to see whether managed rest correlates with improved performance. The Brewers should use that window wisely. Misiorowski has earned the chance to pitch in October — but earning that chance and showing up fresh are two different things entirely.
