Signed by the Sox to a two-year, $9.5 million contract in December 2013, Mujica was designated for assignment Friday. In 13 2/3 innings over 11 games this season, he had a 1–1 record and 4.61 ERA with eight strikeouts and three walks.
Last season, Mujica, who turns 31 on Sunday, appeared in 64 games and posted a 2–4 record with a 3.90 ERA and eight saves.
The season before signing with the Red Sox, he was an All-Star for the Cardinals, going 2–1 with a 2.78 ERA and 37 saves in 64 2/3 innings. He never attained that kind of success in Boston, though the Red Sox have struggled all around him. They went 71-91 in 2014 and are 13–17 after losing, 7–1, Saturday to the Toronto Blue Jays.
