I know that it is annoying, but they do have some reasons.
When Church comes back, Nunez is back to AAA...And they didnt want to waste an Option on Aguila or Pascucci to bring them up for a short stint. THey will come up when rosters expand. I dont agree with the move, because they could drop a catcher and keep them in the majors, but at least they had a reason, right?
But Nunez? Gimme a Break!
