Adam Mazur: Everything you need to know

The Marlins placed Mazur (elbow) on the 60-day injured list Wednesday. The move frees a spot on the 40-man roster. Mazur will miss the entirety of the 2026 season after undergoing UCL reconstruction surgery with an internal brace on his right elbow earlier this month.

Mazur (elbow) underwent UCL reconstruction surgery with an internal brace Wednesday and is expected to make a full recovery in 13-to-14 months, Christina De Nicola of MLB.com reports. De Nicola reported earlier Wednesday that Mazur was ticketed for season-ending elbow surgery, but the nature of his procedure wasn't revealed until the operation was completed. Since he avoided a traditional Tommy John surgery, Mazur may be able to shave a couple of months off his recovery timeline, but he's still likely to open the 2027 season on the Marlins' injured list. Prior to undergoing surgery, Mazur was likely headed to Triple-A Jacksonville to begin the season, but the loss of the 24-year-old right-hander for the entire 2026 campaign represents a hit to the organization's rotation depth.

The Marlins announced that Mazur will undergo surgery Wednesday on his right elbow and will miss the entire 2026 season, Christina De Nicola of MLB.com reports. The report doesn't provide any specifics regarding Mazur's procedure, but the right-hander is presumably ticketed for Tommy John surgery or UCL repair with an internal brace. The latter procedure would give Mazur a chance at avoiding missed time to begin the 2027 campaign, while the right-hander would almost certainly open next season on the injured list if Tommy John surgery is deemed necessary. Even before experiencing discomfort in his elbow last week and getting shut down from throwing, Mazur was facing an uphill battle to make the Marlins' Opening Day rotation and was likely to begin the season at Triple-A Jacksonville. In any event, the loss of Mazur will thin the Marlins' organizational rotation depth.
