Ivanovic sent packing - US Open

Even for the mathematics major from Clemson, it just didn't add up: How could someone who recently struggled so badly she wanted to quit tennis stay on the court with the No. 1 player in the world?
Ana Ivanovic probably wondered the same thing.
In one of the biggest upsets in the sport's history, the top-seeded Ivanovic was ousted from the U.S. Open, stunned by 188th-ranked Julie Coin 6-3, 4-6, 6-3 in the second round Thursday.
Never before in the Open era that began in 1968 had the No. 1 woman lost this early in the tournament. Plus, all the favorites had been breezing at Flushing Meadows.
Coin spent much of the year playing in minor league events and nearly got knocked out of the qualifying event to merely make it into the Open. She recently played so poorly she thought about giving up the sport and relying on her degree.
"I was thinking, 'Am I really made to play tennis?"' she said.
Still, Coin couldn't have figured on it. Asked whether she'd thought such a win was possible, she gave a direct, honest answer.
"No," she said.
And when did she believe it might happen?
"I guess when it was over," she told the crowd at Arthur Ashe Stadium, drawing a huge ovation.
