Mets left-hander could require season-ending surgery

The Mets placed lefty A.J. Minter on the 15-day injured list due to a left lat strain this weekend, but he’ll be out far longer than 15 days. Manager Carlos Mendoza tells the Mets beat that Minter’s injury is “pretty significant” and could require surgery (video link via SNY). A final decision on surgery hasn’t been made yet, as Minter is receiving a wave of additional opinions. However, if the lefty does go under the knife, Mendoza acknowledged that the procedure would end his 2025 campaign.

It’s a brutal development for Minter, who spent the offseason rehabbing hip surgery and has been outstanding in his first 11 innings as a Met. The longtime Braves lefty has allowed only two runs on six hits and five walks with 14 strikeouts so far in 2025. That’s good for a huge 31.8% strikeout rate, albeit against a bloated 11.4% walk rate. Minter has kept a strong 48% of his opponents’ batted balls on the ground and turned in an above-average 12.4% swinging-strike rate.

Minter is one of four Mets relievers with a sub-3.00 ERA on the season (and three with a sub-2.00 mark). The Mets have seen closer Edwin Diaz struggle with command issues even as he’s gone 7-for-7 in save opportunities. Righty Ryne Stanek has also struggled with his command. The group of Reed Garrett, Jose Butto and Huascar Brazoban has been sharp thus far, but on the whole, the Mets are lacking in established veterans to set up for Diaz.

More generally, the Mets are also light on lefties with Minter’s season now in jeopardy. Danny Young is the only currently healthy left-handed reliever in Mendoza’s bullpen (or on the 40-man roster). Brooks Raley just signed a one-year deal, but he’s still on the mend from last year’s Tommy John surgery. Genesis Cabrera is in Triple-A but is not on the 40-man roster and has not pitched well to begin the season.

Minter’s injury also comes with notable contractual ramifications for the Mets. A healthy version of Minter would surely have turned down the player option he faces at season’s end. He signed a two-year, $22M deal over the winter even while recovering from hip surgery. If he’d been healthy and pitched anywhere close to his current level, he’d have been a lock to opt back into free agency.

If Minter undergoes season-ending surgery, he’d almost certainly decide to forgo that out opportunity in his contract. Even if he avoids surgery, it seems like he’ll be facing a monthslong absence, which significantly increases the chances of him exercising his $11M player option. RosterResource already projects the Mets for $206M of tax obligations in 2026, and that’s before factoring in player options (Minter, Frankie Montas, Pete Alonso), club options (Raley, Drew Smith) or arbitration raises (Francisco Alvarez, David Peterson and Tylor Megill, to name a few).
