Indian Wells, 15 March 2011 |

Former world No.1 Dinara Safina has upset Australian Sam Stosur 7-6(2) 6-4 in the third round of the BNP Paribas Open in Indian Wells today.

The win was arguably the Russian’s best since her comeback from a debilitating back injury that kept her off the Tour for several months in 2010.

Victory over the No.4 seed Stosur earnt Safina a quarterfinal match-up with compatriot Maria Sharapova, who ousted Aravane Rezai on Tuesday.
