2024 season: Seattle Mariners' top reliever Matt Brash to miss after Tommy John surgery; expected return in 2025.

Seattle Mariners' top reliever Matt Brash will miss the entire 2024 season after undergoing Tommy John surgery. Brash, who led the majors with 78 appearances in the 2022 season, experienced elbow discomfort during spring training and had a partial tear in the posterior area of his ulnar collateral ligament. The Mariners hope for his return in late spring or early summer of 2025 after his recovery.
