Eight teams have showed interest in reliever Billy Wagner, according to his agent. Agent Bean Stringfellow told WEEI that the Red Sox are one of the teams interested in signing the former closer. "Billy is absolutely, believe or not, open to going back to Boston," Stringfellow said. "If you asked me if he would be open to returning to Boston right after the season ended I would say there was no chance. But he's the one that brought it up to me." "He shared some stories that gave him comfort there in Boston that made him feel like could come back there. It was one of the most positive experiences that he ever had."
