It's no secret that the Yankees would love to add the left hander ace to their rotation, but at what price? They have made it clear that Joba Chamberlain is untouchable, although Phil Hughes and Ian Kennedy can be had for the right price - and Santana, who will be 29 on March 13, could be that player. However, that'll leave the Yankees with a weak bullpen once again if they plan on making Joba a starter.
The Mets, according to Billy Wagner, are being criticized for not making any transactions in the offseason thus far. With Glavine gone, Santana would fit in comfortably in that rotation.
The Angels already have Garland, Colon, and Lackey in their rotation. Adding Santana would only buff up that incredible rotation.
I would like to see Santana go to a team in the process of rebuilding instead of one of these big name teams who already have enough star players to carry them. I mean, c'mon. Does Boston really need another star pitcher? The Tigers of 2 years ago when they went to the World Series is an example of a team that suffered for years before finally assembling a great team. I think he would fit in well with the Blue Jays. The 1-2 punch of Halladay and Santana would be an interesting combination and would help the Blue Jays keep up with Red Sox and the Yankees.
It is also rumored that if the Twins can deal Santana, they may also be interested in trading their closing pitcher Joe Nathan.
