WIMBLEDON, England -- Less than 24 hours after winning her first Olympic singles gold medal, Serena Williams was celebrating again. This time, she had someone to hug following match point.

Williams and her older sister, Venus, defeated Andrea Hlavackova and Lucie Hradecka of the Czech Republic 6-4, 6-4 for the Olympic doubles gold medal Sunday afternoon. The match was played under a closed roof because of rain.

It was the third time the Williams sisters won the Olympic doubles title. They also won in 2000 in Sydney and in 2008 in Beijing. Each sister has four gold medals (three doubles and a singles), matching the career total of Frenchman Max Décugis.

“It was so exciting to win the singles, but like I said at the beginning of the tournament, my goal was to get gold in doubles here,” Serena said. “There’s something about standing next to Venus and holding that gold medal. Three times we have played, three times we have got the gold medal. So we are pretty stoked about it.”

Said Venus: “After coming off Serena’s victory, I think most of all we are happy to add to our country’s medal count and be a part of it.”

So, which feels better — a Wimbledon title or Olympic gold?

“I would say this is more special than Wimbledon,” Venus said. “Serena always said we wanted to win the gold together. I’m amazed she won the singles and our main goal was to win the doubles, so we got both and it’s amazing.”
