The Boston Red Sox, who lost closer Jonathan Papelbon via free agency to the Philadelphia Phillies, are in the market for a replacement.

Boston is among the many teams inquiring about Oakland Athletics closer Andrew Bailey, who is eligible for salary arbitration for the first time. The Red Sox also are keeping tabs on the trade market for Colorado's Huston Street. Ryan Madson, displaced in Philadelphia by Papelbon, is their top free-agent target.

The Red Sox, however, have not ruled out promoting setup reliever Daniel Bard to closer. The 26-year-old right-hander has a career ERA of 2.88 and 9.7 strikeouts per nine innings in three major league seasons.
