Petra Kvitova lost on the US Open's first day

• Wimbledon champion Petra Kvitova, who has struggled on the hard-court circuit since her All-England Club triumph, crashed out of the US Open in the first round Monday afternoon.
• Petra Kvitova was the first big-name to fall (if the US Open goes anything like previous three majors this year, there will be many more in the coming days) as she fell to Romanian Alexandra Dulgheru.
