The Seattle Mariners have signed 27-year-old right-handed pitcher Brendan White to a minor-league contract. White spent six years in the Detroit Tigers organization before being released in July 2025. He has 33 games of major league experience, pitching to a 5.09 ERA in 40 2/3 innings in 2023 before an injury-shortened 2024 campaign and a 7.24 ERA at Triple-A in 2025.

Why it matters

The Mariners are constantly looking to improve their pitching depth, which has been a strength of the organization. While White is unlikely to make the opening day roster, the team believes they can work with him throughout the year and potentially use him at the major league level if needed.
