Papelbon signed a four-year, $50 million deal with the Phillies prior to the 2012 season, but has pitched just twice since the All-Star break, and his last save came July 11.
"He got a real big, luxury contract and things like that, but he also talked about that he wanted to come here because we had guys who could hit homers and we had a good defense," manager Charlie Manuel said. "He thought we had a chance to win and all that. Same reason [Roy] Halladay came here, same reason Cliff Lee came here, and there's been quite a few players like that. I think the way he said it left a lot of interpretation."
