Just a year after putting together one of the best starting rotations in baseball history, the Phillies are facing some changes. Roy Halladay, Cliff Lee and Cole Hamels are all expected to return, but Roy Oswalt is a free agent and has been targeted by a number of other teams. Oswalt was the only "elite" Type A free agent not offered salary arbitration by the Phillies. The Phillies could plug Vance Worley into the fourth spot.
