Red Sox officially sign Edward Mujica

Boston Red Sox general manager Ben Cherington announced the signing of right-handed relief pitcher Edward Mujica to a two-year contract Saturday.

The deal is worth $9.5 million over the two years, a baseball source told ESPNBoston.com on Thursday, when the agreement was first reported.

The 29-year-old Mujica was the closer for a time with the St. Louis Cardinals this past season but lost the job in September and was not a factor in the postseason, making just two appearances.

Over his eight-year career, which has spanned four teams, Mujica has struck out 350 and has walked just 68 in 381 innings.

Mujica joins a strong Red Sox bullpen that's already in good shape at closer (Koji Uehara) and in setup roles (Junichi Tazawa, Craig Breslow), though he could join the late-innings mix.
