The Williams sisters earned an easy 6-4, 6-4 victory over a Czech pairing of Andrea Hlavackova and Lucie Hradecka on Sunday morning at Wimbledon, giving each their fourth Olympic gold -- the most of any tennis player ever.

Serena Williams, fresh off of her singles victory Saturday, became the first woman to win both singles and doubles at the Olympics since Venus did it in 2000. It's the third Olympics doubles victory for the sisters; they've never lost a set, let alone a match, in 15 games.

The match itself was somewhat of a foregone conclusion considering the way Serena has played in London, but the Czech pair made the matchup interesting. There are no eye-popping stats showing the dominance of the sisters, but they were in control the whole way, never allowed their serve to be broken, and won the match in straight sets in under two hours.

America now has three golds on the Olympics in tennis: both men's and women's doubles, as well as Serena's singles gold. They have a chance for two more, as Lisa Raymond and Liezel Huber go for bronze in women's doubles, and Raymond and Mike Bryan compete for the bronze medal match in mixed doubles.
