London, Aug 29: 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.
Meanwhile, British sprinter Mo Farah cruised to victory in the 5000 metres at the World Championships and consequently became the first man to claim a triple-double on Saturday.
The double Olympic champion, who bagged the gold medal in the 10,000m last week, crossed the finishing line for a time of 13min 50.38sec, Sport24 reported.
Kenya’s Caleb Ndiku finished second, ahead of bronze winner Ethiopian Hagos Gebrhiwet.
Earlier, Farah had claimed the doubles at the 2012 London Olympics and 2013 World Championships in Moscow.
