Mariners Trade for Catcher Jhonny Pereda, Designate Jackson Kowar for Assignment

The roster shuffle prioritizes optionable depth at catcher before spring training.

Overview

  • Seattle acquired Jhonny Pereda from the Twins for cash considerations and placed him on the 40-man roster.
  • To clear the spot, the club designated right-hander Jackson Kowar for assignment, and his immediate fate now depends on waivers or a potential trade.
  • Pereda retains one minor-league option and profiles as depth behind Cal Raleigh and Andrew Knizner, likely opening the season at Triple-A Tacoma.
  • Kowar, 29, missed 2024 after Tommy John surgery and ended 2025 with a shoulder impingement, finishing last season with 17 innings for Seattle.
  • Minnesota had recently designated Pereda after signing Victor Caratini, and Pereda owns a .241 average with no MLB home runs over about 50 games.
