Juan Carlos Oviedo (formerly Leo Nunez)
From a positional standpoint, clearly the Orioles need a new backup C. Thus the reason for Flores, Hill, Kottaras, etc.
I also think they could look into a UTIL or MI option such as Getz or Schumaker. They also bring an element to this team that the Orioles have lacked in past years (SB, OBP, versatility).
I put Pagan and Torres on there because I think they could bring in value at a low price. IF they are non-tendered that is.
Pitching wise, those are the guys I think could bring potential value or have bounce-back type seasons.
