Jacob Misiorowski's 38-Inch Waist and a 0.29 ERA Is Rocking the League

Alright, Seattle, listen up, because while our Mariners are doing their thing, there's a pitcher out there who's absolutely lights-out, and it's something you gotta see to believe. Jacob Misiorowski is stepping onto the mound for his first career start against the Astros on Sunday, and honestly, the dude has been on a tear that's straight-up historic. We're talking a May run that puts him in the conversation with franchise legends, rocking a 4-0 record with a ridiculous 0.29 ERA and 49 strikeouts through his first five starts of the month. Plus, he's clocking velocity records for a starter since pitch tracking even began. This is not normal, folks.

A May for the History Books

You want numbers? We got numbers. Misiorowski's May performance isn't just good, it's setting records. His 0.29 ERA for the month is the best in Brewers history for any pitcher with at least four starts, blowing past Freddy Peralta's 0.32 in August 2025. And get this: his WHIP is sitting at an absurd 0.54, topping Corbin Burnes' stellar 0.55 from March/April 2021. Batters are hitting a measly .105 against him, which is just insane. Peralta's best was .109, for crying out loud! The wildest stat of all? Misiorowski has allowed *zero* extra-base hits in May. That's right, a big fat ZERO, joining Cal Eldred from August 1992 as the only pitchers to do that with four starts or more. The guy is practically unhittable right now.

The Secret Weapon Behind the Dominance

And it's not just May, people. Misiorowski's streak extends back into April. He's pitched five-plus innings and allowed no extra-base hits in each of his last six outings. That's a streak tied for the longest such run in a single season since at least 1900, putting him in company with absolute legends like Bob Welch, Jack Coombs, Vic Willis, and Christy Mathewson. In those same six starts, he's racked up 58 strikeouts. He's the first pitcher since at least 1900 to get over 45 strikeouts with zero extra-base hits allowed in a six-game span. So, what's the secret sauce? Brewers pitching coach Jim Henderson spilled the beans: Misiorowski spent the winter focusing on lower body strength. He actually went from a 36-inch waist to a 38-inch waist, requiring all new special-order pants! Misiorowski himself confirmed it, saying, "In the offseason, that was the focus, and I think I came out better on the other side. I feel stronger, but nothing crazy." Looks like that investment in new jeans paid off in a big way. The Astros have their work cut out for them trying to cool this guy off. It's Misiorowski's first career start, and everyone is watching to see if he can keep this unbelievable run going. Meanwhile, back here in the Emerald City, our Mariners just handled their business, taking down the Arizona Diamondbacks 5-1. A good day for baseball, and a great one for the good guys!
