Williams sisters become golden girls

Serena and Venus Williams strolled to Olympic gold

Venus and Serena Williams of the United States crushed Dutch pair Kristie Boogert and Miriam Oremans in straight sets on Thursday to win the Olympic women's doubles title.

The unseeded Americans won 6-1 6-1 to give older sister Venus her second gold medal of the Games.

On Wednesday, she beat Elena Dementieva of Russia to win the singles title.

It was the 22nd straight match victory for the Williams sisters in doubles and the most one-sided women's final in Olympic history. They did not drop a set in the Olympic competition.

Venus Williams joined compatriot Helen Wills - who achieved the feat in 1924 - in becoming only the second player to win women's singles and doubles titles at the same Games.

The Williams' victory means the United States has swept the women's singles and doubles titles at the last three Olympic Games.

Els Callens and Dominique Van Roost of Belgium won the bronze medal on Wednesday when they beat Natasha Zvereva and Olga Barabanschikova of Belarus 4-6 6-4 6-1 in the third-place playoff.
