Williams sisters win historic fourth gold medals

Venus and Serena Williams became the first tennis players to win four Olympic golds on Sunday after a 6-4, 6-4 victory over Czech pair Andrea Hlavackova and Lucie Hradecka in the women's doubles final at Wimbledon. The Williams sisters had already won doubles gold together at the Sydney Games in 2000 and in Beijing in 2008, while Venus claimed the singles gold in Sydney and Serena won her first individual gold on Saturday after crushing Maria Sharapova in the women's final. Venus and Serena also joined Spain's Conchita Martinez, who won silver in 1992 and 2004 and bronze in 1996, as the only tennis players to win medals at three different Olympics.
