Trevor Rosenthal, who was trying to make it back to the majors with the Tigers, will undergo elbow surgery next week.
The team is calling it a UCL reconstruction revision, which will cost him at least the rest of this year. If it’s a full Tommy John, he’ll miss much of next year, too. It’s been very tough sledding for Rosenthal of late, as he needed thoracic outlet surgery in 2021. He hasn’t pitched in the majors since 2020, and he had thrown just three innings in the minors for the Tigers this season.
