The Williams sisters failed to medal in singles but found considerable consolation in doubles, improving their lifetime Olympic record as a team to 10-0. They won the doubles gold at Sydney but didn't play in Athens four years ago because Serena was hurt.
"It does mean more for me to win it with Serena, to share this kind of moment with your sister," Venus said. "I mean, we are practically joined at the hip."
Already assured of the No. 1 ranking, Rafael Nadal was No. 1 at the Olympics. He won a gold medal yesterday, overcoming two set points in the second set and holding every service game to beat Fernando Gonzalez of Chile, 6-3, 7-6 (2), 6-3.
The gold medal was the first for Spain in Olympic tennis and another milestone in an astounding summer surge by Nadal, who will officially end Roger Federer's 4 1/2 -year reign atop the rankings today. Nadal has won 38 of his past 39 matches, including victories over Federer in the finals at the French Open and Wimbledon.
