The Boston Red Sox signed former closer Edward Mujica from the St. Louis Cardinals for two years and 9.5 million dollars. Mujica transitioned to the closer role after Jason Motte underwent Tommy John Surgery. Mujica showed great promise as the closer as he pitched to a 2.78 earned run average across 65 games where he finished 49 games. Mujica isn't much of a strikeout pitcher as he only had 46 strikeouts through 64 and 2/3 innings pitched. He mostly likely will be slotted in to the back of the Red Sox bullpen with Koji Uehara, Junichi Tawaza, Craig Breslow and Andrew Miller.
The market for closers this off-season is extensive which could have played a role in how his contract was under 10 million. Some of the other closers on the market included Grant Balfour, Kevin Gregg, Jose Veras and Chris Perez. The Red Sox efforts might move to signing an outfielder to replace Jacoby Ellsbury. Possible replacements mentioned throughout reports include Matt Kemp via trade, Shin Soo Choo through free agency or filling the need from with in with Jackie Bradley Jr.
