Ivanovic out of US Open

As of now Ana Ivanovic is still the number one ranked female tennis player in the world, she gained this recognition after winning the French Open a couple of months ago.
But, yesterday she got eliminated from the US Open, a competition she was expected to win, and the woman who took her down from her throne was an 188th ranked Julie Coin.
On one side, Coin played above her rank and on the other, Ivanovic showed a poor performance, "Obviously if you would ask me at the moment if I'm playing like No. 1 probably not, but I can't judge too much on that because I really haven't had chance to practice," the Serbian said.
Ivanovic is not too far from losing her number one spot, as other 4 women are true contenders to overtake her, including world No. 2 Jelena Jankovic, No. 4 Serena Williams (both by reaching the semifinals), No. 5 Elena Dementieva and No. 6 Dinara Safina (both by reaching the finals).
