Miami Marlins

Tyler Zuber

RP

The internal brace procedure comes with a shorter rehab timetable than a full Tommy John surgery, but Zuber nonetheless could be sidelined until the 2028 season. Zuber posted a 5.67 ERA in 2026 thanks in large part to 10 home runs allowed in 39.2 innings, but a 42:11 K:BB offered more promise.

Robby Snelling

SP

Snelling required an internal brace surgery in May to repair a UCL tear in his left elbow. The recovery time for that type of procedure is shorter than that of a Tommy John rehab, giving Snelling a chance to contribute to the Marlins at some point before the All-Star break. The left-hander yielded three runs in five innings in his major-league debut in 2026, and he's been dominant at Triple-A Jacksonville the last two seasons, authoring a 1.46 ERA and 132:33 K:BB over 98.2 frames.

Adam Mazur

SP

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.

Anthony Bender

RP

Bender was never able to properly rehab his injury after landing on the injured list in late June, so he'll now opt for the surgical route. The Marlins will likely have more information regarding his recovery timeline following his procedure.

Jakob Marsee

CF

After playing with some discomfort down the stretch of the regular season, Marsee had his elbow examined before opting for surgery. He is expected to be game-ready in six months, putting his status for Opening Day in question. Marsee put together a .231/.348/.359 batting line with 11 home runs and 23 stolen bases this season for the Marlins.
