Shelly-Ann Fraser led a Jamaican clean sweep in the Olympic women's 100 metres despite a late appeal from the American contingent.
It was Jamaican celebration time again following Usain Bolt's record-breaking 100 metres success on Saturday with Sherone Simpson and Kerron Stewart dead-heating to share silver in the first national sweep of the women's 100.
It always looked likely to be a tight one with three Americans and three Jamaicans expected to fight it out.
In the end, however, it was a blur of yellow as Fraser, 21, stormed through to take gold in a personal best 10.78 seconds and her colleagues clocked 10.98.
"I can't believe I actually won. Nobody expected me to," Fraser said. "It's wonderful, the first three for Jamaica. History," Simpson added.
There were nervous moments for the medallists when the Americans appealed against the result, saying one of their own athletes should have been called for a false start, but officials rejected it.
