Milwaukee Brewers right-hander Quinn Priester will begin the season on the Injured List after formally receiving a diagnosis for the wrist issues that have been plaguing him.  

Priester recently met with a specialist that identified the issue as neurogenic thoracic outlet syndrome, according to Brewers beat reporter Adam McCalvy of MLB.com. 

McCalvy also wrote that it occurs when the nerves and blood vessels in the lower part of the neck are compressed, resulting in pain, weakness, fatigue and numbness or tingling in the arm or hand. 

According to McCalvy, Priester has the least serious form of the syndrome that is made up of three varieties. 

After receiving the diagnosis, Priester spoke with McCalvy about what the diagnosis meant for him. 

“Yeah, I'm just kind of excited that we kind of have the diagnosis that we can move through,” Priester said. “I feel like we've kind of been dancing around what some of these issues were and just to be able to have a clear path forward I think is really good.” 

Priester, 25, is entering his second season in Milwaukee. In 2025, he produced a 13-3 record across 29 appearances (24 starts) and a 3.32 ERA.  

Priester said the issue first presented as a nerve. 

“It's nervy, so it's kind of like jumping all the way down to the wrist there and obviously that's how it presented first and then just some other stuff that you know we're able to kind of notice feel a little bit tighter in some areas,” he said.  

“And then just kind of know that something wasn't 100% right and then being able to find out what that was I think is good so that we can attack it and make it right,” Priester said.

Instead of being intimidated by the situation, Preister continues to take an optimistic approach. 

“I don't know, it's more of how you attack the situation,” Priester said. “I kind of go into it with the idea of, ‘Hey, right now we're doing what we can to get me back on the mound’, you know, with the bullpen on the 21st. Those things I think those are the reasons why, you know, we have those goals in mind and with those goals in mind you know you're not thinking negatively.  

“Not [a] very common diagnosis, but ultimately it's becoming more and more common," Priester said. "We're seeing these cases more and definitely feel confident that what we've learned about it so far is going to give me an opportunity to pitch for us this year and as soon as possible. 

"So, just being optimistic and confident I think is the right path forward,” he said,
