Marlins vs Nationals

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.

Conine suffered a left hamstring strain during Thursday's game against Cincinnati and has now decided to go under the knife to treat the problem. He's expected to miss 6-8 weeks following the procedure, setting him up for a return to Miami's lineup in late May or early June.

Jimenez was taken out of Tuesday's game against Atlanta after experiencing neck stiffness due to a collision with Ronald Acuna in the sixth inning. The 25-year-old has recorded just ten hits in 44 at-bats for Miami this campaign. Miami is recalling Graham Pauley in response to Jimenez being placed on the IL.

The Marlins had indicated previously that Snelling would require Tommy John surgery, so it's pleasant surprise that he needed an internal brace procedure instead. The operation Snelling had comes with a timetable of 10-to-12 months, which gives him a good chance to be a contributor for Miami at some point next season.

Henry is ready to pitch in games again after missing more than a month of action with a right rotator cuff strain. He will likely require at least a few rehab outings before rejoining the Nationals' bullpen before the end of May if all goes well.

It's the first bit of throwing the right-hander has done since he was diagnosed with a right flexor strain in late March. He will be brought along slowly in his rehab before being evaluated for a potential return to the Nationals' rotation.

The transaction clears a spot on the 40-man roster for the addition of Richard Lovelady. Waldichuk is likely headed for Tommy John surgery, though he will receive a second opinion before a final decision is made.

Stubbs made his major-league debut in 2025 with the Nationals, going hitless in three plate appearances. The 29-year-old will merely be organizational catching depth for the Blue Jays at Triple-A Buffalo.

Irvin spun five scoreless and hitless innings Saturday, earning the win against Atlanta despite feeling something in the back of his shoulder/lat area during the contest. He tried to throw a warmup pitch prior to the sixth and still felt it, and so the Nationals made the call to remove him from the game. The right-hander will undergo imaging to determine the exact nature and full extent of the issue -- one which Irvin told manager Blake Butera he's dealt with before in the past.
