A couple of companion deals that would send Roy Halladay to Philadelphia and Cliff Lee to Seattle are "close" but "not done," according to two sources familiar with the negotiations.

As part of the deals, Halladay would agree to a three-year extension through 2013, with a vesting option that could lengthen the deal by another year or two, one source said. The extension is expected to guarantee Halladay in the neighborhood of $60 million, plus the $15.75 million he would make in 2010, the final year of his current contract.

The specifics of the trades took some twists and turns on Monday. The latest structure would send three Phillies -- outfielder Michael Taylor, catching prospect Travis d'Arnaud and pitcher Kyle Drabek -- to Toronto, sources said.

Under that scenario, the Phillies would not have to include their top position-player prospect, Domonic Brown, and they would receive Seattle's top pitching prospect, Phillippe Aumont, who originally appeared ticketed for Toronto.

The Phillies would receive one other prospect -- believed to be 21-year-old outfielder Tyson Gillies -- from Seattle in the other trade for Lee, who is a year away from free agency.

Indications are that the Phillies also will receive a third prospect in the deal, but it wasn't clear Tuesday morning whether that player would come from Toronto or Seattle. However, ProspectInsider.com reported the third prospect is Mariners right-hander Juan Ramirez.

Initially, sources said, Toronto was to receive Aumont, d'Arnaud and another Phillies prospect in exchange for Halladay. The Phillies had balked at sending Brown.

Phillies doctors also have to sign off on Halladay's physical.

The Associated Press reported that J.A. Happ, Joe Blanton and Brown also took physicals in Philadelphia on Monday, but that was before specifics of the deals started to come out.

The AP also reported that the commissioner's office granted a 72-hour window on Sunday for Toronto and Philadelphia to complete their trade.

If all of the names being bandied about wind up in this deal, the Phillies would get back what Baseball America rates as the Mariners' top two pitching prospects, plus an outfield prospect (Gillies) they view as being similar to Taylor. So although the Phillies would be giving up two of their most highly regarded prospects in Drabek and Taylor, they would look at this deal as not significantly depleting their system for the long haul.
