Brewers call up Brian Fitzpatrick for MLB debut after perfect Triple-A start

Brian Fitzpatrick did not just get the call to Milwaukee. He forced it.

The 6-foot-7 left-hander from Smithtown, New York, was selected from Nashville on April 29 and was set for his major league debut that night after rolling through 10 Triple-A appearances with a 0.00 ERA. In 10.1 innings for the Sounds, Fitzpatrick allowed nothing, struck out 11 and posted a 0.87 WHIP, the kind of line that makes a front office stop talking about upside and start talking about timing.

The Brewers drafted Fitzpatrick in the 10th round in 2022 out of Rutgers, and the path since then has been about building a reliever who could move quickly. His Triple-A work in 2026 was the cleanest argument yet. Milwaukee did not need him to pitch well someday. Nashville had already shown he could miss bats now, and the Brewers decided the next test belonged in the majors.

The roster move came with a cost. Angel Zerpa was placed on the 15-day injured list, retroactive to April 28, with left forearm tightness, and the Brewers’ injury notes described the absence as potentially lengthy while additional testing was planned. Zerpa, acquired from Kansas City in a December trade, had been viewed by Milwaukee as a key power arm. Matt Arnold previously called him a “really big arm” with a sinker-slider combination the club wanted to deploy behind its defense. That arm is now on hold, and Fitzpatrick gets the opening.

Milwaukee also sent Luis Matos outright to Nashville after he cleared waivers on the same day. Matos had been acquired from the Giants for cash on March 31, a move tied to Jackson Chourio’s Opening Day injury and the Brewers’ search for a right-handed bat. The transaction log made the picture clear: Fitzpatrick’s promotion, Zerpa’s injury move and Matos’ outright all landed together as Milwaukee reshuffled its roster.

For Fitzpatrick, the opportunity is the payoff for a Triple-A run that left little room for debate. A 0.00 ERA in 10 outings is not a fluke when it comes with strikeouts, a sub-1.00 WHIP and a rapid rise from draft pick to debuting big leaguer. Milwaukee bet that what played in Nashville will carry over immediately, and now Fitzpatrick gets the chance to prove it where it counts most.
