Mujica, 29, went 2-1 with a 2.78 ERA and 37 saves in 65 appearances. He went 37-for-41 in saves last season. For his career, Mujica has a career 3.75 ERA, 1.13 WHIP, and a .256 BAA in eight big league seasons, spending time with the Cleveland Indians (2006-2008), San Diego Padres (2009-2010), Miami Marlins (2011-2012), and St. Louis Cardinals (2012-2013).
The Red Sox bullpen definitely needed some work following last season. In 2013, the Red Sox bullpen went 30-23 with a 3.70 ERA (21st in MLB) and a .250 BAA (23rd in MLB). Expect Mujica to be the setup guy there.
