Seattle Mariners Face Key Veteran Reliever Exits, Josh Naylor Free Agency Challenges

The Seattle Mariners face critical decisions this offseason after a strong 2025 season that ended in a narrow loss to the Toronto Blue Jays in the American League Championship Series. Central to their offseason focus is the impending free agency of Josh Naylor, who has been a key offensive contributor since joining the team but may not have strong sentimental ties to Seattle, making his return uncertain amid competition from other teams. Additionally, the Mariners must consider cost-cutting moves in their bullpen, potentially non-tendering veteran relievers Gregory Santos and Trent Thornton to save money for retaining major free agents like Naylor or upgrading the roster. Should Naylor depart, the Mariners could pursue Pete Alonso as a replacement; Alonso's recent performance and comments on his uncertain future with the Mets make him a strategic fit for Seattle's winning aspirations. Management's challenge will be balancing payroll flexibility with maintaining a competitive roster, especially as they navigate retaining key players and potentially adding new talent to sustain their postseason push.
