What happened: Milwaukee Brewers starter Quinn Priester is set to undergo thoracic outlet decompression surgery on Monday and will miss the remainder of the 2026 season. The procedure ends his year before he could factor into the rotation, after the club had recently paused his rehab assignment amid command struggles.

Why it matters: Losing Priester for the full season removes a depth option from a Brewers staff that has carried the team to one of the National League's best records. The timing compounds an already difficult rehab stretch and forces Milwaukee to look elsewhere for rotation and bullpen reinforcements as the schedule tightens.

What to watch: Watch for the Brewers' roster response and any timeline on Priester's recovery, with a return not expected until the following season.
