I don't know a lot about the farm system, but I would do that. I doubt Seattle would, though.
I'd do it just so I didn't have to listen to people talk about Iglesias anymore. Everyone wants to bring him up because "His defense is so good, it doesn't matter that he can't hit worth a damn". The thing is, if he has an historic defensive season, the best anyone has ever had, but bats .200, the same people who clamored to replace Aviles or Ciriaco with him will spend every gamethread posting nothing but "f*** Iglesias" "oh, another strikeout, what a surprise", and so on.
I have no problem with promoting guys from the minors, but not until they are hitting there like they really want to play here. If getting rid of Iglesias and pretty much any other minor leaguers gets the Sox Hernandez, I'd say do it.
