New York's starting rotation will be comprised of Opening Day starter CC Sabathia, Hiroki Kuroda, Andy Pettitte, Ivan Nova and David Phelps.
Closer Mariano Rivera will be joined in the bullpen by David Robertson, Joba Chamberlain, Boone Logan and Shawn Kelley, plus Eppley and Warren.
The Yankees are carrying two catchers, Francisco Cervelli and Chris Stewart, and five infielders: Robinson Cano, Jayson Nix, Eduardo Nunez, Lyle Overbay and Kevin Youkilis.
New York has five outfielders on the active roster, carrying Brennan Boesch, Ben Francisco, Brett Gardner, Ichiro Suzuki and Vernon Wells.
In order to create room on the 40-man roster for Overbay, who was signed to a Major League contract on Sunday, the Yankees have designated left-hander Clay Rapada for assignment.
The Yankees have also placed Phil Hughes (right upper back thoracic injury), Derek Jeter (recovery from left ankle surgery), Mark Teixeira (right arm torn ECU sheath) and Curtis Granderson (fractured right forearm) on the 15-day disabled list.
They had previously placed Cesar Cabral, Michael Pineda and Alex Rodriguez on the 60-day disabled list.
