The Red Sox have announced that Joel Hanrahan will close in 2013, meaning Andrew Bailey will be demoted to the role of set up man.

Boston acquired Hanrahan from Pittsburgh in a trade that was completed on Wednesday.

John Farrell felt it important to be up front with both players from the get-go.

"(Hanrahan's) performance pretty much speaks for itself," Farrell said. "This is a multi-year All-Star closer. We went into the offseason with the goal of improving the team however we could. We didn't go in precisely looking to add a closer, but the Hanrahan addition to a strong bullpen makes it that much stronger as we stand here today."
