As things stand right now, this is the roster …
Gardner or Cabrera CF
Hughes, Kennedy or Aceves
Ransom or a utility infielder type
Cabrera or Gardner
Albaladejo, Veras, Robertson, Ramirez, Coke or Melancon (pick three)
Giese or Aceves
Meanwhile, somebody has to come off the 40-man roster once Teixeira is officially added.
There is a trade to be made somewhere. Here’s a rough list of expendable (at least some some degree) Yankees:
Any reliever other than Rivera or Marte
Melky Cabrera or Brett Gardner
Meanwhile, Jesus Montero should dedicate himself to the Tony Pena School of Catching. First base is no longer an option. And stop aging Derek Jeter and Jorge Posada. First base is not an option for you, either.
