Miami Marlins

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.

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.

Pete Fairbanks

RP

Fairbanks was ruled out for the season upon landing on the injured list Tuesday with nerve irritation in his right hand, and now that he's confirmed to be dealing with thoracic outlet syndrome, he'll go under the knife to treat the issue. A timeline for his return should emerge after his procedure, though he'll likely have to sit out the first portion of the 2027 campaign.

Max Meyer

SP

Meyer landed on the 15-day injured list just after the All-Star break because of a neck strain. He resumed throwing earlier this month in a last-ditch effort to make a late-season return, but the decision has been made to shut the right-hander down. Meyer will undergo further evaluation before the next steps of his rehab are determined, but it seems at this juncture that the 27-year-old should be ready to roll by spring training. The righty will finish the 2026 season with a 2.68 ERA, 1.14 WHIP and 121:41 K:BB over a career-high 111 innings.

Owen Caissie

RF

Caissie was initially diagnosed with hamstring tightness after being removed from Saturday's game against the Dodgers. However, further tests have revealed a lower-back injury for the 24-year-old outfielder, and he won't be eligible to return until the last week of the regular season. Xavier Edwards (thumb) was reinstated from the 10-day IL in a corresponding move, and Esteury Ruiz figures to see more playing time in the outfield for as long as Caissie is sidelined.

Andrew Nardi

RP

Arm specialist Dr. Keith Meister will perform Nardi's surgery, but the Marlins aren't expected to provide specifics on the procedure until the operation is completed. If Nardi requires a UCL repair or reconstruction rather than something less significant such as a flexor tendon surgery, he'll likely wind up missing the entire 2027 season. Nardi posted a 5.16 ERA, 1.41 WHIP and 27:11 K:BB while collecting three wins and eight holds over 22.2 innings with Miami this season before hitting the shelf May 30.

William Kempner

RP

The transaction clears space on the 40-man roster for the addition of Logan Driscoll. Kempner recently underwent UCL surgery on his right elbow and will be sidelined, at minimum, until late in the 2027 season.

Ronny Henriquez

RP

Henriquez has already been ruled out for the entirety of the 2026 campaign after undergoing UCL reconstruction surgery in the offseason, but the fact that he's now playing catch is a very encouraging sign of progress. Assuming his rehab continues smoothly, he should be ready for the start of spring training in 2027.
