Edward Mujica to temporarily take over as closer for the Red Sox

WEEI’s Rob Bradford reports that Red Sox manager John Farrell has temporarily removed Koji Uehara from the closer’s role and inserted Edward Mujica. Uehara has slumped, allowing runs in five of his last six appearances. That includes last night’s stint in which he allowed a game-tying solo home run to Mark Teixeira and a walk-off solo homer to Chase Headley in the ninth inning.

Farrell stressed that Uehara is healthy and that the right-hander isn’t being shut down for the season, as has been speculated. Bradford adds that Uehara himself requested to be taken out of the closer’s role.

Uehara had one of the best relief seasons of all time last year, finishing with a 1.09 ERA, 21 saves in 24 opportunities, and a 101/9 K/BB ratio. He also only gave up five home runs. This year, he has a 2.64 ERA with 26 saves in 30 chances and a 75/8 K/BB ratio. The two home runs Uehara allowed last night bumped up his total to 10, doubling last year’s allowance.

Mujica, who closed for the Cardinals — the runner-up in last year’s World Series — has had mediocre results as a set-up man in the Red Sox bullpen, posting a 4.13 ERA with a 39/11 K/BB ratio in 52 1/3 innings.
