Now that they're officially in, I figured this thread was appropriate. It's worth noting that Cashman said they would carry ten pitchers. So we'll go with the assumption that the Yankees' will carry fifteen position players and ten pitchers.
Definite Position Players:
Catchers: Posada and Molina
Infielders: Teixeira, Cano, Jeter, and Rodriguez
Outfielders: Swisher, Gardner, Cabrera, Damon, and Hinske
Designated Hitter: Matsui
That leaves three spots open. The options are Hairston (if healthy), Pena, Cervelli, Guzman, Duncan, and Miranda.
I think they take Hairston, Pena, and Guzman.
Definite Pitchers:
Starting Pitchers: Sabathia, Burnett, and Pettitte
Relief Pitchers: Rivera, Hughes, Robertson, Aceves, and Coke
That leaves two spots open. The options are Chamberlain, Marte, Gaudin, and Bruney.
I think they take Chamberlain and Marte.
