Mets Set MLB Record With 46 Pitchers After Dom Hamel Debut

The record underscores a season of instability that forced New York to chase outs with rookies.

Overview

Dom Hamel, 26, debuted with a scoreless sixth inning in a 7-4 loss to the Padres, becoming the Mets’ 46th pitcher of 2025.
The total surpasses the single-season mark previously held by the 2024 Miami Marlins.
Injuries and role changes upended the staff, including Kodai Senga’s demotion, Griffin Canning’s ruptured Achilles, Sean Manaea’s move to bulk relief, Frankie Montas’ season-ending UCL injury and Tylor Megill’s elbow sprain.
New York has leaned on late-season rookies Nolan McLean, Brandon Sproat and Jonah Tong after August as David Peterson faded and the Clay Holmes starter experiment stretched the staff.
Turnover was so extreme that three position players — Luis Torrens, Travis Jankowski and Jared Young — pitched, even as the bullpen ranks 17th in ERA with a heavy innings load and the club holds the final NL wild-card spot.
