Having joined the Seattle Mariners via a trade mid-way through the 2025 season, infielder Josh Naylor wasted no time in establishing himself as a fan favorite at T-Mobile Park.In the 54 regular-season games he played for the Mariners, Naylor batted .299 with 9 home runs and 33 RBIs, while also being as reliable as ever in defense. The 28-year-old's fine performances helped his team win the AL West for the first time since 2001, and make it to the ALCS in October.As he entered free agency once the season concluded, fans implored the organization to re-sign the infielder, and they got their wish on Monday, as Naylor agreed to five-year, $92.5 million deal.Featuring in a clip the Mariners uploaded to X, Josh Naylor sent a heartfelt message to fans soon after signing."Mariners fans, I am so excited to be a part of this group now, for multiple years.
