The Mariners have designated catcher Seby Zavala for assignment, per a team announcement. His spot on the roster will go to first baseman Ty France, who’s been reinstated from the 10-day injured list. Seattle’s 40-man roster is now down to 37 players.
Acquired alongside flamethrowing relief prospect Carlos Vargas in the offseason trade sending Eugenio Suarez and his remaining salary to the D-backs, Zavala entered the 2024 season as the primary backup to catcher Cal Raleigh. He’s only appeared in 18 games and taken 43 plate appearances, however, in part due to Raleigh’s iron-man workload — his 503 innings behind the dish rank second in MLB to William Contreras — and also due to some pronounced struggles in that limited playing time. Zavala is batting just .154/.214/.282 with a 37.2% strikeout rate thus far.
The Mariners signed former Twins and Rangers catcher/designated hitter Mitch Garver to a two-year pact over the winter, with the idea that Garver would serve as the full-time designated hitter. But as Garver has begun to heat up after a dreadful start at the plate (.229/.413/.571 over his past 46 plate appearances), the Mariners have begun using him at catcher more frequently. He’s still only made four appearances at the position, but they’ve all come in the past two weeks. And whether it’s coincidence or not, Garver’s turnaround at the plate has dovetailed with the team’s decision to begin plugging him back into the catcher’s spot on occasion.
With Garver now factoring into the catching equation, Zavala’s grip on a roster spot appeared increasingly tenuous. He’s a glove-first, light-hitting backup who’s always been prone to whiffs, as evidenced by a career 35.9% strikeout rate. The Mariners have been seeking ways to inject some life into a lackluster offense that has thus far been supported by a dominant pitching staff. Plugging Garver into that backup catcher role is one logical way to do that.
Though Zavala is highly prone to punchouts and carries an unsightly .205/.271/.342 batting line in 557 big league plate appearances, he’s a premium defender with particularly strong marks for his framing and ability to block balls in the dirt. Zavala is out of minor league options, so the Mariners didn’t have the ability to simply send him to the minors.
As such, Zavala will now be traded or placed on outright waivers within the next five days. Waivers themselves would be a 48-hour process. Within a week’s time, Zavala will know whether he’s cleared waivers or is headed to another team, either via trade or claim. He’s been outrighted previously, so if he goes unclaimed he’d have the right to reject a minor league assignment in favor of free agency.
