For now, anyway.
The Yankees haven't sent out an official roster yet, but with Francisco Cervelli being sent to AAA and Justin Maxwell designated for assignment, we can safely assume that this will be the Yankees Opening Day Roster:
David Phelps will serve as the long reliever; Clay Rapada will be the second lefty in the bullpen, unless Boone Logan's back injury turns out to be worse than initially thought, in which case he will be the only lefty. Maxwell, who hit .310 and played well in the outfield this spring, was a victim of the numbers crunch; just no room on this roster for another outfielder. Stewart, acquired late this afternoon from the SF Giants in exchange for George Kontos, will serve as the backup catcher.
