Mariners Bolster Bullpen Depth, Ink Former Tigers Reliever Brendan White to Minor League Deal

The Seattle Mariners have signed right-handed reliever Brendan White to a minor-league contract, adding experienced bullpen depth. White, 27, previously spent six seasons with the Detroit Tigers, making his MLB debut in 2023 before struggling with injuries and command in 2024 and 2025, eventually landing in independent baseball.

The Mariners will look to help White regain his form, likely assigning him to Triple-A Tacoma to start the season, hoping he can contribute to their pitching-focused organization.
