Max Kranick to undergo Tommy John surgery

Mets reliever Max Kranick is slated to undergo Tommy John surgery, per Newsday’s Laura Albanese. It’ll be the second time he’s undergone Tommy John surgery in the past 37 months.

It’s a brutal blow for Kranick, who’s finally in the process of establishing himself as a solid big league arm after a lengthy layoff from his first UCL procedure, performed back in June of 2022. Kranick, then with the Pirates, missed nearly all of the 2023 season.

The Mets claimed Kranick off waivers in January 2024 and kept him on in the minors all last season. He got his first look with them in 2025 — his first MLB work since 2022 — and has been quite effective. In 37 innings, he’s recorded a 3.65 ERA. Kranick’s 16.9% strikeout rate is well below average, but his 3.4% walk rate is the fifth-best among the 347 big league pitchers who’ve tossed at least 30 innings in 2025.

Given the timing of the procedure and the fact that it’s his second Tommy John, Kranick could miss the entire 2026 season. At best, he’d be a candidate to return next September. He’s arbitration-eligible for the first time this winter, so there’s a decent chance the Mets will decline to tender him a contract. Keeping him would mean dedicating a 40-man spot to Kranick all offseason, as there’s no 60-day injured list in the winter.

For the time being, Kranick will head to the 60-day injured list the next time the Mets need to open a 40-man roster spot. He’ll continue accruing major league service time and pay for the remainder of the current season. If the Mets opt to keep him on the roster all winter, they can immediately place him on the 60-day injured list when camp opens next spring. Kranick can be controlled through the 2028 season.
