Miami Marlins

Christopher Morel

LF

Morel is set to undergo further evaluation, after which the Marlins will have more information regarding his status. In the meantime, Connor Norby will fill in as Miami's first baseman while Owen Caissie enters the lineup as the designated hitter.

Kyle Stowers

LF

The 28-year-old outfielder is beginning the season on the IL and will be re-evaluated in 3-4 weeks, meaning that Stowers will probably need at least a brief rehab assignment before he's ready to make his 2026 debut in late April or early May. If he continues to make good progress in his recovery, however, he could return on the short end of that estimate. The Marlins will miss having Stowers' bat in the lineup after he had a breakout 2025, slugging 25 homers with a .912 OPS in 117 contests.

Esteury Ruiz

LF

Ruiz sustained a high-grade left oblique strain in this past Friday's Grapefruit League game against the Nationals. The expected recovery time is 6-to-8 weeks, which will keep him out of action until at least mid-May. With Ruiz and Kyle Stowers (oblique) both sidelined to start the season, the Marlins bolstered their outfield depth by signing Austin Slater to a one-year contract Tuesday.

Maximo Acosta

SS

Acosta already looked to be facing an uphill battle to make the Opening Day roster, and the injury he suffered last week will bring an end to any chance he had. Once he heals up and resumes full baseball activities, the 23-year-old infielder will report to a minor-league affiliate for a rehab assignment. Acosta has two minor-league options remaining, so he could end up sticking around at Triple-A Jacksonville once he completes the rehab assignment and gets activated from the injured list.

Adam Mazur

SP

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.
