PARIS, France - It was another day and another win for the Williams sisters in doubles at the French Open on Friday, as the American tandem defeated Sara Errani and Kirsten Flipkens, 6-4, 6-2.

After rallying from a set down in their opening round victory, the sisters again pulled off a comeback effort in both sets in the second round.

They came from 4-2 down in the opening set to win the last four games, and also came from an early break down in the second set to safely advance to the third round.

The Williams sisters will next face the winners of the second round encounter between Irina-Camelia Begu and Wang Qiang, who won their first round match on Friday, and Andreja Klepac and María José Martínez Sánchez.
