A series of trades that would send Roy Halladay to the Phillies and Cliff Lee to the Mariners are "close" but "not done," according to sources. As part of the deals, Halladay would agree to a extension with Philadelphia through the 2013 season. The Associated Press reported that the commissioner's office granted a 72-hour window on Sunday for the Blue Jays and Phillies to work out the deal. A number of prospects are expected to be a part of the deal, but nothing has been finalized.
