Italy's Sara Errani became the first woman into the French Open quarter-finals when she knocked out former champion Svetlana Kuznetsova of Russia 6-0 7-5 on Sunday.
Claycourt specialist Errani, who had never gone beyond the second round at Roland Garros before this year, reeled off the first eight games before Kuznetsova won her first game, on a break.
Kuznetsova, the 2009 champion who had beaten Errani in five previous meetings, hit a succession of shots into the net to give away matchpoint in the 12th game and then put a forehand wide.
Errani, seeded 21st, will now meet 10th-seeded German Angelique Kerber.
