Out · expected back around May 1
Mazur underwent UCL reconstruction surgery with an internal brace in March. He had been tentatively expected to begin a throwing program in September, though it's unclear whether he's checked that box yet. Mazur might not be an option for the Marlins until around midseason, as he'll likely require time in the minors to knock the rust off.

Latest news
Marlins president of baseball operations Peter Bendix said Tuesday that Mazur (elbow) should be ready to pitch in games by April or May of next season, Isaac Azout of FishOnFirst.com reports.
Mazur underwent UCL reconstruction surgery with an internal brace in March. He had been tentatively expected to begin a throwing program in September, though it's unclear whether he's checked that box yet. Mazur might not be an option for the Marlins until around midseason in 2027, as he'll likely require time in the minors to knock the rust off.

Mazur (elbow) is expected to begin a throwing program sometime in September, Christina De Nicola of MLB.com reports.
Mazur is already set to miss the entire 2026 campaign after undergoing UCL reconstruction surgery with an internal brace in March, but starting a throwing program in September keeps the door open for him to return at the start of the 2027 campaign.

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.

Mazur reported discomfort in his right elbow Friday and will see a specialist after getting imaging done, Craig Mish of FanDuel Sports Network Florida reports.
It's bad news for Mazur, who's pushing for a spot on the Marlins' Opening Day roster. The 25-year-old posted a 4.80 ERA and a 1.50 WHIP across 30 big-league innings last season for Miami and hasn't allowed a run in three innings of action during spring training. More information regarding Mazur's health should be available in the coming days.
