Seattle Mariners Sign Reliever Brendan White to Minor-League Deal

The 27-year-old returns to affiliated ball as organizational bullpen depth following an injury-hit stretch.

Overview

  • The signing was announced by the Atlantic League’s Lancaster Stormers and recorded in MLB’s official transactions log.
  • White appeared in 33 games for the Tigers in 2023, posting a 5.09 ERA over 40 2/3 innings.
  • He lost most of the 2024 season to injury before Detroit non-tendered him and later brought him back on a minor-league deal.
  • Detroit released him in July 2025 after a difficult stint at Triple-A Toledo, and he finished the year with the independent Lancaster Stormers.
  • Seattle is expected to assign him to Triple-A Tacoma as a depth option who could be considered for a call-up if he regains form.
