Serena Williams defeated Maria Sharapova Saturday in the gold medal match of women's singles tennis, said The Guardian.
Williams dominated the match 6-0, 6-1, and completed a career Golden Slam in doing so - having won championships at the US Open, French Open, Australian Open, Wimbledon, and the Olympics, said the Los Angeles Times.
Williams is only the second player in history to have a Golden Slam, the first being Steffi Graf, said The Guardian.
"I've never played better," said Williams, "I thought: 'If my career's over, I have my gold medal and now I have everything," according to The Guardian.
Sharapova, who suffered the worst finals loss in Olympic history, also would have achieved a career Golden Slam with a win, said The Guardian.
Williams could earn her fourth career gold medal if she wins her upcoming gold medal doubles match with sister and partner Venus, said the Los Angeles Times.
