Roy Halladay has been spotted in Philadelphia and could soon be a member of the Phillies. Sources have told FOX Sports that a three-team blockbuster that would send Halladay to Philadelphia and Cliff Lee to a third team. A straight trade between the Phillies and Jays also is possible, according to the sources. Halladay could be in Philadelphia to either take a physical or negotiate a contract extension. The third team that is likely involved in the deal hasn't yet been confirmed, but the Mariners and Angels are possibilities. The trade is complex because Toronto could end up paying Philadelphia some money to pay a portion of Halladay's salary in 2010.
