Greg Rutherford of Britain won gold in the men's long jump on Saturday, leaping 8.31 meters.
Rutherford claimed the gold when Will Claye of the United States, the only man who could have caught the Briton, fouled his last attempt.
Mitchell Watt jumped 8.16 to take the silver for Australia, with Claye winning bronze with 8.12.
The winning jump was four centimeters short of Rutherford's own world-leading time this year.
It was Britain's second gold in 20 minutes after Jessica Ennis won the 800 meters to take the top prize in the women's heptathlon.
