The Mariners and catcher Mitch Garver have reached agreement on a minor league contract, sources told ESPN's Jeff Passan on Wednesday.

Garver, 35, is expected to compete with Andrew Knizner and Jhonny Pereda to back up Seattle catcher Cal Raleigh, the runner-up for AL MVP last year. Garver spent the last two seasons as Raleigh's backup, though he signed with the Mariners initially to serve as their primary designated hitter.
