Mariners’ Logan Gilbert Trade Cost Takes Unexpected Turn After Insider Report

Trading Seattle Mariners pitcher Logan Gilbert could involve veteran swaps instead of prospect returns due to looming MLB labor uncertainty, according to insider Jon Morosi. With Gilbert entering his final year of team control before 2027 free agency, clubs are reportedly hesitant to surrender top prospects because of potential work stoppages tied to the collective bargaining agreement expiring on December 1.

Rather than seeking prospects, Seattle could explore exchanging Gilbert for an established major-league hitter entering free agency to bolster their struggling lineup. The 29-year-old right-hander posted a 3.73 ERA across 32 starts in 2026 and is projected to earn $15.4 million through arbitration.
