Reigning Australian Open and U.S. Open champion Kim Clijsters has regained the #1 ranking for the first time since her August 2009 return to the WTA Tour. Clijsters will replace Caroline Wozniacki when the rankings are released on Monday. Clijsters barely won her first match as World #1, beating Kaia Kanepi 6-1 7-5 in the semifinals of the Open Gaz de France semifinals and will face 2011 Australian Open quarterfinalist Petra Kvitova (who dismissed Bethanie Mattek-Sands 6-2 6-0) in the final on Sunday.
Last year's tournament was won by Elena Dementieva over Lucie Safarova in one of the best women's tennis matches of the year. It would be the Russian's last tour title since she retired from tennis later in 2010.
