I missed this in the tour de france
Venus actually defeated Serena

I thought Serena was gonna win with her past record but not to be
This was Venus' first victory over her younger sibling in a Grand Slam final since the 2001 U.S. Open, and it evened their career record at 8-8.
"I can't believe that it's five," Venus said. "But when you're in the final against Serena Williams, five seems too far away. ... She played so awesome, it was really a task to beat her."
Venus came from 3-1 down in the first set to turn around the match, breaking Serena four times while dropping serve twice in a final that produced breathtaking tennis despite swirling wind.
