The 34-year-old Sherrill rejoins the Mariners, whom he had previously been with from 2004-2007. He also spent time with the Orioles, Dodgers and most recently the Braves before coming to a full circle. Sherill is a your prototypical lefty-one-out-guy from the bullpen, and is most effective when used in that role. In his career, Sherrill holds lefties to a .180/.241/.275 slash line.
