Should I grab Jose Contreras of waivers right now? When will Brad Lidge be back?

No your fine. Lidge will be on the 15 day DL. I think the Phillies are going to swap around players in the closers role. Maybe one night they will pitch Contreras and the next Madson. I wouldn't count on the Phillies saying Jose Contreras is the closer, and bringing him in for most of the save opportunities.
