Mariners Negotiate for Catcher Andrew Knizner
13 Dec, 2025
Summary
- Mariners negotiating to sign catcher Andrew Knizner.
- Knizner played five seasons with the Cardinals.
- Knizner offers solid defense and veteran presence.
The Seattle Mariners are actively seeking to bolster their catching depth by negotiating with free agent Andrew Knizner. Knizner, a 30-year-old backstop, was originally a seventh-round draft selection by the St. Louis Cardinals in 2016. He spent five seasons in St. Louis, accumulating 255 games played, 17 home runs, and a .621 OPS.
While Knizner's offensive contributions were modest during his tenure with the Cardinals, his strengths lie in his defensive capabilities and his role as a steady veteran presence. The Mariners, who rely heavily on Cal Raleigh, are considering Knizner as a valuable backup option to provide support and stability behind the plate.
This potential acquisition follows the departure of last season's backup, Mitch Garver, who is now a free agent, and the trade of Harry Ford to the Washington Nationals. Knizner's addition would offer the team experienced coverage at the catcher position.
