In a move that’s sure to spark conversations among baseball fans, the Seattle Mariners have just signed catcher Andrew Knizner to a 1-year Major League contract, locking him in through 2026. But here’s where it gets interesting: this addition brings the Mariners’ 40-man roster to 39 players, leaving just one spot open—and that’s a detail that’s already got fans speculating about what’s next. Could this be a strategic play to keep flexibility for future signings? Only time will tell.
Knizner, a 30-year-old veteran with a journeyman’s resume, has spent parts of seven Major League seasons with the St. Louis Cardinals (2019-2023), Texas Rangers (2024), and most recently, the San Francisco Giants (2025). During his 33-game stint with the Giants last season, he batted .221 (17-for-77) with 12 runs, 1 double, 1 triple, 1 home run, 5 RBI, and 7 walks. Perhaps most impressively, he didn’t allow a single passed ball over 234.0 innings behind the plate—a stat that highlights his defensive reliability. But is his bat enough to make him a long-term asset? That’s a question that’s sure to divide opinions.
Standing at 6-foot-1 and weighing 225 pounds, Knizner carries a career .211 batting average (186-for-881) with 33 doubles, 1 triple, 19 home runs, 90 RBI, 4 stolen bases, and 70 walks. His on-base percentage sits at .281, with a .596 OPS across 323 Major League games. While his offensive numbers might not jump off the page, his defensive consistency could be what the Mariners are banking on. And this is the part most people miss: in a league where catching depth is often a challenge, Knizner’s experience and reliability behind the plate could prove invaluable.
Originally drafted by the St. Louis Cardinals in the 2016 MLB First-Year Player Draft out of North Carolina State University, Knizner made his Major League debut on June 2, 2019. His journey since then has been a rollercoaster, with stops in Texas, Arizona, Washington, and now San Francisco before landing in Seattle. Is this the opportunity he’s been waiting for to solidify his place in the big leagues? Or is he just another piece in the Mariners’ puzzle?
Here’s a thought to chew on: With the Mariners’ roster nearly full, what does this signing say about their strategy for the upcoming season? Are they prioritizing depth over star power? And more importantly, do you think Knizner’s addition will make a significant impact, or is this just a stopgap move? Let us know in the comments—this is one conversation that’s bound to get heated!
