Mariners Near Deal With Catcher Andrew Knizner to Back Up Cal Raleigh

Seattle shifted off a Mitch Garver reunion after trading prospect Harry Ford, signaling a preference for a steady veteran behind the plate.

Overview

  • MLB.com reports Seattle is nearing a Major League agreement with Andrew Knizner pending a physical, with no official announcement yet.
  • The move would bring the Mariners’ 40-man roster to 39, per the report, as the club continues to seek bullpen help.
  • Seattle’s need for a backup intensified after Harry Ford was dealt to Washington for reliever Jose A. Ferrer and last year’s No. 2, Mitch Garver, entered free agency.
  • Knizner, 30, spent 2025 with the Giants after a difficult 2024 with Texas, posting a .221/.299/.299 line in 33 games before being designated for assignment in November.
  • The Mariners value Knizner’s experience and game management for a low-usage role behind Raleigh, and they also plan to add upper-minors catching depth before spring training.
