Closer Andrew Bailey is likely to be activated from the disabled list in time for Monday's game in Chicago after making a rehab appearance at Triple-A Pawtucket on Saturday night.

Bailey, who has been on the disabled list since April 29 with a strained right biceps, was scheduled to join the Red Sox in Minneapolis on Sunday, manager John Farrell said. He threw 17 pitches in an inning of work at Pawtucket on Saturday night, and Farrell said "physically, he came through it fine.

"He showed consistent velocity," Farrell said. "He'll get checked up on it, as anybody would, in a situation like this, but he came out of last night fine."

For a team that has already endured some bullpen turmoil this season, with closer Joel Hanrahan undergoing Tommy John surgery, Bailey's return will bring some stability back to Boston's bullpen.

Farrell said the team will be careful about using Bailey on back-to-back days initially, but when he is available, the Red Sox relievers will know their roles.

"To slide guys back a little bit earlier, it gives us that flexibility with Junichi (Tazawa) a little more, rather than holding him back to close out games," Farrell said. "I think just getting guys back one slot earlier in the game certainly makes us stronger and gives us added depth in the pen."

The starting pitcher for Pawtucket on Saturday night -- left-hander Franklin Morales -- was also there on a rehab assignment, but his results weren't very encouraging.
