Red Sox reliever Craig Breslow got a favorable clubhouse endorsement from the guy he supplanted on the 25-man roster.

Breslow was summoned from Triple-A Pawtucket yesterday to replace right-handed set-up man Andrew Bailey in the Red Sox bullpen. Bailey went on the 15-day disabled list with a right biceps strain before last night’s opener of a four-game series with the Twins at Fenway Park.

Bailey and Breslow have a working relationship that predates their time on the Red Sox. Breslow served as Bailey’s set-up man for three seasons with Oakland.

Breslow made four rehab relief appearances with Pawtucket while recovering from shoulder tendinitis, and was ready to go last night.

“He’s a great teammate and obviously a great baseball player and it’s nice to have him back,” said Bailey. “He’ll be a great addition to our bullpen and he’s a guy who has thrown in 75 games for the last how many years.

“His numbers are always great, so it’s nice to have him back. We were joking last year that about 100 percent of my saves in (Oakland) he set up for us and hopefully we can get that back. As a unit down there (in the bullpen) we will be pretty strong and he’s a great lefty to have down there.”

Manager John Farrell said the bullpen needed a fresh arm following the Red Sox’ six-game road swing through Toronto and Texas. Farrell wants Breslow to play an expanded role while keeping Andrew Miller as the Red Sox left-handed specialist.
