You are trying to talk about ruining clubhouse chemistry on a team run by Ozzie Guillen that has moved this guy out of the position he wants to play, and has done nothing but lose games. Why would you expect him to be anything other than unhappy?
I understand what Castellanos is, and I also understand what Peralta and Ramirez are. I'd make that trade.
I have no idea about the validity of the comments, but I remember hearing the clubhouse stuff well before Guillen took over.
