LONDON  - Serena Williams demolished Russia's Maria Sharapova 6-0, 6-1 to grab Olympic tennis singles gold on Saturday, becoming the first player in the sport to win all four grand slams and an Olympic title in both singles and doubles.

Earlier, Sharapova’s team mate Maria Kirilenko lost out on the bronze to world number one Victoria Azarenka of Belarus, who defeated the Russian 6-3 ,6-4 to win the country's first ever tennis medal.

Having completed the career "golden slam", the unstoppable American, who dropped just 17 games in her six Olympics singles matches, is now making plans away from tennis. "I've won everything. Now I can go to Disneyworld," said the 30-year old, laughing. It was the most one-sided women's singles final in Olympic tennis history, beating the previous record for the fewest games set by France's Suzanne Lenglen when she defeated Britain's Dorothy Holman 6-3 6-0 in Antwerp in 1920. "I never played better," Williams said. "I don't feel anything invincible. I don't feel anything. I just feel good about my game and I practiced so hard and it was time."

Sharapova, making her Olympic debut, was happy just to go home with a medal. "She was just too quick and too powerful today," she said.

Meanwhile, America's Bob and Mike Bryan won their first Olympic gold medal with a 6-4, 7-6 (7/2) victory over French second seeds Jo-Wilfried Tsonga and Michael Llodra in the men's doubles final.
