This may be one of the biggest in tennis history and is certainly one of the biggest in U.S. Open history. 1967 was the last time the number one ranked woman lost in the second round of the Open. 188th ranked Julie Coin of France defeated top seed and world number one, Ana Ivanovic, 6-3, 4-6, 6-3, today in Arthur Ashe Stadium. Women’s tennis is in pretty sad shape right now. A world number one really shouldn’t have a loss like this. Ana really needs to get her act together. Some time off might be in AI’s future.
