US Open disqualification

I've seen some nasty verbal abuse to the chair umpires in matches, but I've never personally seen anyone getting disqualified for it. I wonder what exactly this girl said.

The 2006 US Open Junior Championship got off to a rather interesting start this afternoon when No. 2 seed and Wimbledon winner Caroline Wozniacki of Denmark was disqualified from the tournament. The 16-year-old, who had won the first set over 17-year-old Russian Alexandra Panova, was ousted after verbally abusing an umpire during the second set. US Open

It appears the argument was over whether or not a shot was in or out. What a way to waste your chances at another championship.
