SERENA WILLIAMS survived another French Open scare as the top seed was tested to the full by American compatriot Sloane Stephens on court Philippe Chatrier.
With second seed Maria Sharapova tumbling out of the tournament earlier yesterday, that should have given Williams extra motivation in the hunt for a third Roland Garros title.
However, the top seed instead struggled to a 1-6 7-5 6-3 fourth-round victory in two hours against her 22-year-old opponent.
Williams will now face 17th-seeded Italian Sara Errani in the quarter-finals.
Defending champion Sharapova crashed out after she was beaten in straight sets by Lucie Safarova.
