Usain Bolt secured his third gold medal of the world championships when he anchored Jamaica to 4x100m relay win in Beijing on Saturday.
The Jamaican team of Nesta Carter, Asafa Powell, Nickel Ashmeade and Bolt romped home in a world-leading 37.36 seconds, the Guardian reported.
American rival Justin Gatlin was on course to bag his third silver medal, but a careless baton change between Tyson Gay and Mike Rodgers saw the USA disqualified just minutes after the race.
