Mariners first baseman Josh Naylor left Monday's 3-2 win against the Mets with back spasms after hitting a tying home run in the seventh inning. Manager Dan Wilson indicated the injury likely occurred during the swing. Naylor's back stiffened as he returned to the dugout, forcing him to exit the game. Patrick Wisdom replaced him at first base for the remainder of the contest.

The 28-year-old slugger signed a $92.5 million, five-year contract last November after being acquired from Arizona last July. Naylor got off to a slow start this season, hitting just .102 through Seattle's first 15 games. However, he turned it around in May, batting .296 with one homer, three doubles, and nine RBIs across 108 at-bats.

Naylor's immediate availability for Tuesday's game remains uncertain with his day-to-day status. The injury comes at a challenging time for Seattle as they navigate a crucial stretch of games. Naylor's power and consistency have been valuable to the Mariners' lineup since his mid-season arrival last year. His absence could impact the team's offensive production in the short term.
