The upsets keep coming - especially on the women's side. The number 1 seed - Victoria Azarenka has lost and today, the defending champ, Na Li lost. Also, former champ Kuznetsova is out. If she can hold on, it looks like Maria Sharapova may win and complete a career grand slam!

On the men's side, Rafa Nadal appears invincible. In contrast, Djokovic and Federer are struggling. Don't rule out Del Potro! Also, even though he said he could not win prior to the tournament, Jo-Wilfred Tsonga (the 5th seed) is still in the running just may have the tournament of his career!
