Ana Ivanovic, the No. 1 player in the world, is out of the U.S. Open before the first weekend.
The 25-year-old Coin is ranked 188th in the world and has never played in a Grand Slam before, and this is already being called the biggest upset in U.S. Open history. Coin broke Ivanovic three times in a match that lasted nearly two hours, finally winning 6-3 4-6 6-3.
The Serbian Ivanovic looked like the next big thing in tennis when she won the French Open this year, but she has been disappointing since. She lost in the third round at Wimbledon, withdrew from the Olympics with a thumb injury and had a mediocre showing in a three-set win over Vera Dushevina on Tuesday. Now she's out of the U.S. Open.
Coin, who is from France but played NCAA tennis at Clemson, will play Amelie Mauresmo in the third round.
