Garver is expected to begin the season as Seattle's No. 2 catcher, Daniel Kramer of MLB.com reports.
The 35-year-old re-signed with the Mariners as a non-roster invitee in February and will once again served as the backup catcher to Cal Raleigh. Garver still needs to be added to the big-league roster, but the club isn't expected to finalize the roster until Wednesday. During the 2025 regular season, Garver clubbed nine homers and produced a .640 OPS over 87 games.
