If you are interested in womens, then the Toray Pan Pacific open is on next week. Features some of the top womens players like Azarenka, Sharapova, Radwanska, Kvitova, Stosur, Kerber Errani, Li Na etc... And Shvedova (which makes the tournament even more worth watchin )
Well, Azarenka, Sharapova and Serena have made it (i think). The other places are occupied by Radwanska, Kvitova, Kerber, Errani and Li Na. I don't know if any of them are guaranteed to make it or not, but they should do really. The other challengers are Stosur and Bartoli, but only Li Na should be challenged for her spot really.
