Seattle Mariners Secure Mitch Garver as Backup Catcher for 2026 Season

As the Seattle Mariners prepare for the 2026 season, they have confirmed Mitch Garver as their backup catcher, a decision influenced by teammate Cal Raleigh. After Raleigh encouraged Garver to reconnect with the Mariners, he reached out to general manager Justin Hollander and signed a minor league deal. This development comes after Garver's challenging tenure with the team, where he struggled as a designated hitter in 2024, posting a .172 batting average and a .627 OPS over 114 games. In 2025, Garver transitioned to a backup catcher and platoon role, where he found more success, particularly during the postseason.

Garver's performance in the 2025 postseason, where he contributed significantly, has led to a more favorable perception among fans and management. MLB Network analyst Jon Morosi noted that Garver's experience as a World Series champion and his improved mindset have positioned him well for the upcoming season. Morosi emphasized that Garver has earned his spot on the roster through his performance and the respect he commands from teammates.

A key consideration for Mariners' manager Dan Wilson will be managing Cal Raleigh's workload behind the plate. In 2025, Raleigh started 119 games and caught over 1,072 innings, including all 12 postseason games. Morosi highlighted that balancing Raleigh's playing time with opportunities for Garver will be crucial for the team's success throughout the season. This strategy aims to prevent fatigue for Raleigh, who also participated in the World Baseball Classic earlier this year.

Jon Morosi remarked on Garver's improved situation, stating, “Part of the reason why it’ll be different is I think he himself is in a different headspace, and it seems like the fans are also more welcoming.” This sentiment reflects the Mariners' confidence in Garver's ability to contribute effectively in his new role.

While the Mariners' decision to retain Garver has been met with optimism, some analysts may question the team's reliance on a player who previously struggled. Critics might argue that Garver's past performance raises concerns about his consistency and ability to handle the backup catcher role effectively over a full season.

As the Mariners head into the 2026 season, the focus will be on how well they can manage the dual responsibilities of Garver and Raleigh. The team's strategy regarding player rotations and workload management will be closely monitored as they aim for a successful campaign.
