Slovakia's Dominika Cibulkova produced one of the best performances of her career to dump world No 1 Victoria Azarenka out of the French Open in the fourth round.
Azarenka, the top seed from Belarus, had survived a scare in the first round on Monday when unheralded Italian Alberta Brianti pushed her all the way, but there was no let-off on Sunday as 15th seed Cibulkova clinically completed a 6-2 7-6 (7/4) triumph in one hour 47 minutes.
Contrasting emotions: Azarenka saved the first after an entertaining rally
Defending champion Li Na suffered the shock of the tournament after she was sent crashing out of the French Open in the fourth round.
The Chinese player was beaten 3-6, 6-2, 6-0, by world No 142 Yaroslava Shvedova.
Li, who defeated Francesca Schiavone in the final last year, looked to be in control of the match in the opening set but the cool and windy conditions did not help her and she succumbed to the greater consistency of Shvedova.

Caroline Wozniacki was world No 1 this time last year, but has slipped so badly that she is now No 9 (cue debate about whether it is all down to her romance with Rory McIlroy).
The result, Kim Clijsters kept her Australian Open title defence on track by moving into the semi-finals with victory over Caroline Wozniacki - stripping the Dane of her No 1 ranking in the process.
