Serena Williams powers into French Open quarters Serena Williams remains on track for the French Open women's title, after setting up a quarter-final with another former champ in Svetlana Kuznetsova. SERENA Williams bludgeoned her way to another lopsided win at the French Open she continued her quest for a second French Open title, 11 years after her first. The top seeded American needed just 70 minutes to dispose of the world's top doubles player, Roberta Vinci of Italy, 6-1 6-3 and in four matches at Roland Garros this year, she has dropped just 10 games. Kuznetsova, who outlasted eighth seed Angelique Kerber of Germany 6-4 4-6 6-3, said she would relish going up again against Williams, even given her current form. Williams said that she expected a tough match every time she comes up against Kuznetsova. "I mean, the last time we played here she won, so that will probably get her pumped up and she's on a comeback," she added. She has nothing to lose but everything to gai. She also wants to do well, and she's won this tournament before. I have had some pretty tough matches this claycourt season, and I think for sure that will be another one. Also through to the last eight was last year's runner-up Sara Errani who overcame stomach pain at the end of the first set to defeat Carla Suarez-Navarro of Spain 5-7 6-4 6-3. The Italian will take on fourth seed Agnieszka Radwanska of Poland who defeated the 2008 champion Ana Ivanovic of Serbia 6-2 6-4 in the last match of the day. The victory for Williams takes her career-best winning streak to 28, the third longest since 2000 behind sister Venus (35) and Justine Henin (32).
