Brewers shift – Milwaukee has moved Quinn Priester’s rehab assignment to the Arizona Complex League as the right-hander continues recovering from thoracic outlet syndrome. The decision comes after he has yet to pitch in 2026 and endured a punishing run with the Nashville Soun
When Quinn Priester finally steps back on a mound, it won’t be in the same place he’s been fighting his way through this latest stretch. The Milwaukee Brewers have shifted the right-hander’s rehab assignment to the Arizona Complex League, a move driven by ongoing struggles in Triple-A Nashville.
Priester has not pitched this season while working through a lengthy, inauspicious recovery from thoracic outlet syndrome. The condition has denied him the chance to build on what looked like a real breakthrough in 2025, and the Brewers have now adjusted the setting in hopes of getting him on track.
The shake-up couldn’t come with stronger context. Priester, a 25-year-old right-hander, was repeatedly shelled while pitching for the Nashville Sounds. In seven innings of work, he posted a 25.71 ERA and a 4.29 WHIP, a brutal start that left little doubt the reset he’s seeking can’t be cosmetic.
Priester’s troubles trace back to last summer, when he initially experienced wrist soreness. The issue was eventually diagnosed as thoracic outlet syndrome, turning what might have seemed like a manageable problem into something that has lingered and sapped his momentum into 2026.
Even with the Brewers showing patience, the stops and starts have begun to wear on everyone watching from the outside. Pat Murphy, the two-time reigning National League Manager of the Year, said the situation has been hard on Priester.
“It’s killing him,” Murphy said about Priester’s stops and starts, according to Todd Rosiak of the Milwaukee Journal Sentinel. Murphy also pointed to the near-term as the key window to evaluate what comes next.
“He’s such a competitive kid. I think we’ll know in the next month (how it’s trending).”
There is a clear appeal to the Arizona Complex League setting. Murphy believes it will be beneficial for the 2019 first-round draft pick, but the grind of this recovery has already been taxing enough that the Brewers can’t afford false starts.
Priester’s season-long absence has heightened the stakes of this rehab decision. He’s coming off a breakout campaign in 2025, when he compiled a 3.32 ERA with 132 strikeouts and a 1.239 WHIP in 157 1/3 innings. If the Brewers are going to see that version of Priester return. the path likely needs to include more than just time—it may require a deeper solution. one that fans can’t stop wondering about.
The question hanging over this move is whether thoracic outlet syndrome will eventually push him toward surgery once and for all. Time will tell if Priester can reestablish himself as a key component of Milwaukee’s starting pitching rotation. For now. he’s headed to The Desert with one goal: to rediscover his mojo. and do it before the frustration turns into something even harder to fix.

Arizona Complex League? so like spring training but worse lol.
Thoracic outlet syndrome sounds made up. If he’s shelled that bad, why not just give up on him? 25.71 ERA is insane.
Wait, didn’t he get hurt in Nashville? I feel like this is just the team moving around blame like “oh it’s the league”. Also I’m confused bc it says wrist soreness but then thoracic outlet?? that’s basically the same thing right?
Brewers switching his rehab to Arizona doesn’t surprise me, Nashville Sounds probably just chewed him up. Still sucks because he had that 2025 breakthrough and then boom—on the shelf again. I read somewhere “it’s killing him” and I believe it, poor dude. Also 4.29 WHIP?? that’s like every batter was on base, that’s rough.
