When it comes to Olympic sprints, nobody does it better than the Jamaicans. Yeah, mon.

The Caribbean island of 2.8 million people capped the first gold-medal double of men's and women's 100-metre dashes since 1988 with a rare gold-silver-silver in the women's race. It also was the first medals sweep of any 100 since 1912, and the first ever for the women's 100 in any Olympics or world championship. After never winning Olympic gold in the 100, Jamaica got two in as many days.

Shelly-Ann Fraser won the women's dash Sunday, pumping her fist as she was clocked in 10.78 seconds. Teammates Sherone Simpson and Kerron Stewart finished in a dead heat for the silver, 0.20 second back - the same margin Jamaica's Usain Bolt won by Friday night when he hotdogged to the finish in 9.69.

Fraser knew she had won and smiled wide, showing those braces, and then went to pick up the green, yellow and black Jamaican flag. It was the widest margin of victory in an Olympic women's 100 final since 1988, when Florence Griffith-Joyner set the world record.

"When I was thinking about it, I was getting ahead of myself," Fraser said about a gold medal. "I was like, 'Calm down. First you need to go out there and do it'."

She did, and after she crossed the finish line more than a body length in the lead, reggae music played in the background during a three-minute delay while judges looked at the photo finish. There was no way to split the difference, so Jamaica got the top three spots and didn't even have to settle for a bronze.

"It's about time," Stewart said when asked what the sweep meant. "We've been waiting on this. So many great athletes have come so close."

Jamaica's big win turned into a giant disappointment for the United States. Lauryn Williams finished fourth, Muna Lee fifth and Torri Edwards last. Lee, the only one of that US trio with another chance for an individual medal - in the 200 - said she thought there was a false start.
