Charleston, South Carolina: Reigning U.S. Open champion Samantha Stosur prevented another matchup in the Williams sisters' sibling rivalry by beating Venus Williams in three sets on Friday at the Family Circle Cup.
The second-seeded Stosur won five of the last six games of the match for a 6-3, 4-6, 6-3 victory in the quarterfinals on a chilly, windy Friday at the season's first clay-court event. Stosur now has a chance of knocking out both Williams sisters on consecutive days when she meets Serena in Saturday's semifinals.
While Stosur had never beaten Venus Williams before, she has had success against Serena. Stosur beat her to win the U.S. Open title last September and won their only match on clay at the 2010 French Open quarters.
