Mariners signed RHP Michael Rucker to a minor league contract with an invitation to spring training.

Rucker hasn’t resurfaced in the majors since making 96 relief appearances for the Cubs from 2021-2023, posting a respectable 4.57 FIP and 120/50 K/BB ratio across 123 1/3 innings during that span. The 31-year-old journeyman righty didn’t pitch anywhere last year after spending the previous season in the Phillies system. He’s merely emergency organizational depth at this juncture of his career.
