T.R. Sullivan has a new mailbag up...he predicts Cat is traded or released at the end of spring training and fields several questions on the catching situation, mentioning that you could see renewed Boston/Texas trade talk at the end of the spring.
He also appears to still be a member of the Joaquin Arias fan club:
The Rangers need to keep an open mind as to who is ready to play shortstop right now: Arias or Andrus. There is little doubt here that Arias could be a frontline Major League shortstop if not for his shoulder problems.
The club has pretty clearly made a decision on this issue, although Sullivan has been a fan of Arias (and Travis Metcalf) for a while, and I think he'd like to see those two get a legit shot.
