Ken Rosenthal of FOX Sports hears that the Angels and Cardinals will have a hard time assembling a package enticing enough for the Blue Jays to part with Roy Halladay. One GM said the Angels have "zero chance" at acquiring the Jays ace. Players like Brandon Wood and Howie Kendrick have lost some of their appeal and prospect Jordan Walden finds himself on the DL for the second time this season.Halladay would be a good fit in St. Louis, and Brett Wallace could be the centerpiece of a deal, but the Cards may not have the young pitching the Jays seek.The Phillies have enough prospects to make a deal and Rosenthal suggests we should never rule out the Yankees. Here are a few more rumors: The Dodgers are interested in Halladay, Jason Frasor and George Sherrill. The White Sox would probably have to part with Gordon Beckham to acquire Doc.  The Jays and White Sox haven't discussed an Alex Rios deal recently, but the White Sox have long been interested in the Jays outfielder.   Jason Bay is close to setting a cutoff date for negotiations on an extension with the Red Sox.
