Mariners Claim RHP Troy Watson From Tigers, Assign Him to Triple-A
Seattle fills an open 40-man roster spot by claiming the 29-year-old right-hander, who posted a 2.81 ERA over 170 minor-league innings in 2025-26.
The Mariners claimed right-hander Troy Watson off waivers from Detroit, filling an empty spot on their 40-man roster. Watson, 29, was designated for assignment by the Tigers weeks after being selected to their 40-man, a move that freed a spot for Corey Julks. He has been strong in the upper minors recently, posting a 2.81 ERA across 170 innings over the last two seasons. Seattle will use him as starting or long-relief depth at Triple-A Tacoma, and he retains two option years after this season.
