Bailey throws rehab inning for PawSox

Red Sox reliever Andrew Bailey pitched one inning in a rehab outing for Pawtucket on Saturday night against Indianapolis, allowing one run and two hits (a home run to outfielder Brett Carroll and a double to catcher Tony Sanchez) while striking out two.

Manager John Farrell had said on Thursday that Bailey, who is on the disabled list with a strained right biceps, is on track to be activated Monday in Chicago.

With Joel Hanrahan facing season-ending surgery for a torn flexor muscle in his right elbow, Bailey will slide back into the closer's role, Farrell said. Bailey has been on the disabled list since May 6, retroactive to April 29.

Bailey last pitched on April 28, when he pitched a scoreless ninth inning, allowing one hit, against the Houston Astros. Before being hurt, Bailey had run off five saves in five chances, striking out 11 in six innings and holding opponents to a .100 batting average (2-for-20).
