08:49 AM ET 08.05 | A Marlins official told us management has made too many staffing changes for its own good, pointing out the the offense has performed worse under hitting coach Eduardo Perez (.241, last in National League in runs), that it did under fired predecessors Jim Presley and John Mallee. (The Marlins were hitting .250 and 10th in runs scored when Mallee was dumped in June 2011.) "Hanley Ramirez won a batting title under Jim Presley," the official reminded. "You can't change guys all the time. You don't get rid of them if you can't replace them with anyone better." It might be awkward to dump Perez because his father Tony is a special assistant to the president. Keep in mind that Logan Morrison, Gaby Sanchez and Chris Coghlan did their best work under Mallee, but Marlins officials didn't like that he socialized with players, according to another team official.
