On the same day as Serena Williams' defeat, older sister Venus Williams was upset by World No. 26 Flavia Pennetta, who had never previously advanced past the fourth round of the French Open, in the third round, adding to her recent history of early exits at the French Open. This marked the first time since the 2004 French Open that both the Williams sisters were defeated within 24 hours of each other; on that occasion, both were defeated in the quarter-finals by Jennifer Capriati and Anastasia Myskina, who then went on to contest a semi-final between each other.
