The Padres designated Adcock for assignment Sunday.
The right-handed reliever will give up his spot on the 40-man roster to catcher Blake Hunt, who was called up from Triple-A El Paso to provide depth behind the plate after Freddy Fermin (concussion) joined Luis Campusano (toe) on the injured list Sunday. Adcock made three appearances in the big leagues for the Mets in 2025 but had been pitching exclusively in the minors this season, logging a 7.15 ERA and 1.59 WHIP in 11.1 innings across stops with three of the Padres' affiliates.
