Edward Mujica has agreed with the Red Sox on a two-year, $9.5 million deal, according to Yahoo! Sports.
The 29-year-old right-hander was a member of the St. Louis Cardinals the past two years and lost his job as closer to Trevor Rosenthal during September after struggling while being bothered with a groin injury.
He finished last season with a 2.78 ERA and 37 saves in 64.2 innings.
He posted an 11.05 ERA in 7.1 innings in September and pitched just 2.0 innings during the playoffs. His ERA rose a little more than a run during September.
Mujica has very good command, walking just 1.4 batters per nine innings during his career.
Overall, this seems like a good deal for Boston. He is a backup plan at closer in case Koji Uehara struggles after he pitched the most innings in one season of his major league career in 2013.
