Mariners Sign Josh Naylor to Five-Year Deal

The Seattle Mariners have made a significant offseason move by signing first baseman Josh Naylor to a five-year contract. This deal, which is pending a physical, follows Naylor's impressive performance since joining the Mariners from the Arizona Diamondbacks mid-season. Over a span of 54 games with Seattle, Naylor posted a batting average of .299, amassing nine home runs and 33 RBIs, showcasing his ability to contribute offensively. In addition, he demonstrated speed on the base paths, stealing 19 bases during his time with the Mariners.

According to ESPN, this signing is pivotal for the Mariners, who have been searching for a long-term solution at first base for nearly two decades. The franchise has struggled in this position since trading John Olerud back in 2004. Mariners president of baseball operations Jerry Dipoto made it clear that re-signing Naylor was a top priority following the team's heartbreaking loss to the Toronto Blue Jays in Game 7 of the American League Championship Series. Manager Dan Wilson praised Naylor's impact, noting his intensity and drive to win as significant assets for the team.

Naylor's overall performance in the 2025 season was also noteworthy, as he finished with a total of 20 home runs and 92 RBIs across all games, along with a career-high 30 stolen bases. His offensive numbers, particularly his .295 batting average over the entire season, reflect his consistent performance at the plate. ESPN highlights that Naylor's ability to make contact is crucial for a Mariners lineup that has struggled with strikeouts; he ranked in the 17th percentile for strikeout rate among qualified hitters in 2025.

Moreover, Naylor's offensive prowess is complemented by his defensive skills, as he has consistently ranked above average in defensive metrics, despite not being known for his speed. His performance at T-Mobile Park has been particularly favorable, hitting .304 and slugging .534 in his career at the venue. This combination of hitting and fielding prowess makes Naylor a valuable asset for the Mariners as they aim for World Series aspirations in the 2026 season.

In summary, the Mariners' decision to lock in Naylor for five years reflects their commitment to building a competitive roster for the upcoming season and beyond. As they look to improve upon their previous postseason run, Naylor's presence in the lineup is expected to play a crucial role in their success.

With this signing, Seattle fans can look forward to Naylor's continued contributions and the potential for a bright future with the team.
