Miami Marlins

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.

Tyler Zuber

RP

Zuber was diagnosed with a right elbow sprain in mid-September, and he'll be examined soon in hopes of gaining further clarity. UCL surgery is a possibility with this type of injury, but it's uncertain at this point whether an operation is likely.

Jakob Marsee

CF

It's unclear how long Marsee's elbow has been bothering him, but more will be known about his status following his visit with Dr. Meister. Marsee did not show signs of being hurt in September, slashing .342/.441/.544 with three home runs and a 10:14 BB:K.

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.

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.
