Mariners Re-Sign Naylor in Major Offseason Move for 2025

UPDATE: The Seattle Mariners have made a significant splash in the 2025-26 MLB offseason by re-signing first baseman Naylor to a five-year contract. This move marks the first major signing of the winter and underscores the team’s commitment to building a competitive roster for the upcoming season.

This urgent development comes just days after the Mariners concluded their season with a heartbreaking loss in Game 7 of the ALCS. The front office prioritized bringing back Naylor, who played a pivotal role in the team’s late-season success. With this deal, Mariners fans can expect a familiar face returning to a lineup that aspires for a championship in 2026.

Naylor, who joined Seattle from Arizona at the trade deadline, delivered impressive stats over his tenure, hitting .299/.341/.490 with nine home runs and 33 RBIs in just 54 games. His full season performance in 2025 included 20 home runs and a 2.2 WAR, showcasing his value to the team.

The Mariners have long struggled to find a solid first baseman since trading away John Olerud in 2004. Naylor’s return is seen as a critical step in addressing this long-standing issue. He has consistently proven to be a high-contact hitter, finishing with one of the best strikeout rates in the league last season, demonstrating his ability to make contact in a lineup often plagued by strikeouts.

Notably, Naylor has thrived at T-Mobile Park, boasting a career .304 batting average and a slugging percentage of .534 over 43 games at the venue. His performance in Seattle emphasizes his love for the stadium and adds to the team’s hopes of attracting talent despite its pitcher-friendly reputation.

This five-year contract, which will take Naylor through his age 33 season, presents a calculated risk for the Mariners. While he is not yet a superstar, his consistent performance and reliability make him a crucial component for a team aiming for playoff success.

“The front office will be happy with this signing and so will Mariners fans,” said ESPN analyst David Schoenfield.

As the offseason progresses, Mariners fans should stay tuned for further updates and analysis on potential signings and trades. With Naylor back in the fold, the team looks to build on its recent successes and make a deeper playoff run in the upcoming season.
