Left-hander Tony Watson is retiring after 11 seasons as one of the steadiest left-handed relievers in the majors, he told The Athletic on Monday.

Watson, 36, had a 2.90 ERA for the Pirates, Giants, Dodgers and Angels, ending with a return to San Francisco late last season. He posted a 2.96 ERA in a late-inning role for the Giants down the stretch, but a left shoulder strain kept him off the playoff roster. A free agent last offseason, Watson held workouts for MLB teams this spring but had lingering left shoulder issues and decided it was time to call it quits.
