London - 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 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.
As well as dominating for over a decade on the singles tour, Venus and Serena are a formidable doubles team - they have won 13 Grand Slam doubles titles as well as their three Olympic golds - and they were just too strong for the Czechs in a match played under the Centre Court roof due to rain.
Hlavackova and Hradecka won their first Grand Slam title at the French Open earlier this year and had dropped just one set en route to the Olympic final.
But Venus and Serena's record against the Czech fourth seeds - they had won all four meetings including the Wimbledon final last month - hardly suggested an upset was on the cards.
The American sisters made an ominous opening as they broke in the first game of the match.
Hlavackova and Hradecka battled gamely to get back in the match, but Venus and Serena saved a break point at 5-4 to take the set.
Nothing was going to stop the sisters claiming their record haul of golds and they landed the decisive break in the fifth game of the second set.
It was left to Serena to close out the win. With her serve so deadly at present, the result was never in doubt and the sisters were soon hugging in triumph.
