Mariners Sign Veteran Catcher Andrew Knizner to Back Up Cal Raleigh

The move fills a backup-catching vacancy created by Seattle's trade of prospect Harry Ford to Washington.

Overview

  • Seattle announced an agreement with free-agent Andrew Knizner, positioning the 30-year-old as Raleigh's reserve in 2026.
  • The contract is for one year and is reportedly worth $1 million, according to FOX 13 Seattle citing MLB.com's Daniel Kramer.
  • Knizner spent 2019–23 with the Cardinals, appearing in 255 games with a .215 average, a .621 OPS and 1.5 bWAR.
  • He struggled with the Rangers in 2024 (.167/.394 OPS, -0.9 bWAR) but rebounded with the Giants in 2025 (.221/.598 OPS, 0.3 bWAR in 33 games).
  • With Mitch Garver a free agent and Ford dealt to the Nationals, Knizner becomes the likely No. 2 catcher, and local reporting suggests Seattle could seek alternatives if needed.
