Usain Bolt defended his 200 m title with ease and took his tally of World Championship gold medals to seven.
The Jamaican set a world leading time of 19.66 seconds at the World Atheltics in Moscow to secure his third successive world title in the event.
Usain Bolt’s compatriot Warren Weir clinched silver with a personal best 19.79 while America’s Curtis Mitchell (20.04) took bronze by a hundredth of a second.

His winning time was nearly five tenths slower than his personal best, the world record time of 19.19 he set in Berlin, and the slowest of his gold-medal wins over the distance.
But with Tyson Gay absent through suspension and his compatriot Johan Blake injured, Usain Bolt did not have to produce a vintage display to secure the result the vociferous sell-out crowd in the Luzhniki Stadium expected.
By the time the world record holder celebrates his 27th birthday on Wednesday, he could see his name alongside Americans Carl Lewis, Michael Johnson and Allyson Felix as the most decorated gold medallist in the championships’ history.
The speed of Usain Bolt’s progress to the top of that list of high achievers depends on Sunday’s 4×100 m sprint relay final.
Usain Bolt regained his 100 m world title and won a fourth individual World Championships gold with a season’s best of 9.77 seconds in Moscow.
In heavy rain, the 26-year-old Jamaican made amends for his false start in Daegu two years ago and further cemented his status as the greatest sprinter in history.
The six-time Olympic champion overtook Justin Gatlin in the final stages, forcing the American to settle for silver in 9.85.
Usain Bolt’s compatriot Nesta Carter (9.95) claimed bronze, while Britain’s James Dasaolu was eighth (10.21).
It was another convincing victory for Usain Bolt, who demonstrated his superiority by equalling the eighth-fastest time of his career in unfavourable conditions.
Such is Usain Bolt’s dominance of the event, he does not have to be at his quickest to win major championships.

Justin Gatlin, who beat Usain Bolt in Rome in June, said: “I’m getting closer, I’m very happy with my race. The last 30m I got long. In Rome I was able to… do my race, which I didn’t do tonight.
“He [Usain Bolt] has been working on his start – in Rome he had the best reaction out of everybody and he is 6ft 5in. I had to make sure I was beating him to 50 m.”
James Dasaolu, who ran 9.97 in the semi-finals earlier on Sunday, said: “I got to 50 m or 60 m but then they just started to run away from me.
“I think the semi-final took it out of me, but I made it through three rounds and I’m happy that I’m injury free and I can continue with the rest of the season.”
The sight of Usain Bolt surging past his rivals is now a familiar one, as is his fooling around at the start line – as the rain bounced off the Moscow track, he mimed holding an umbrella.
When the gun went, his reaction time of 0.163 sec was equal to that of main rival Justin Gatlin, and the pair were shoulder-to-shoulder before Usain Bolt eased away.
Perhaps the only disappointment of the evening was that the Luzhniki Stadium was not full for the championships’ blue riband event.
Those who were there, however, saved their loudest cheers for the man charged with lifting the sport after a spate of failed drug tests, the most recent concerning Trinidad and Tobago sprinter Kelly-Ann Baptiste.
But neither the rain nor doping scandals could dampen the celebrations as Usain Bolt, with flashbulbs lighting up the stadium, embarked on a jubilant lap of honor.
South African Paralympic champion Oscar Pistorius might consider competing at this year’s World Athletics Championships in Moscow, his agent has told the Associated Press.
Oscar Pistorius, who has run at both the Olympics and Paralympics, is charged with murdering girlfriend Reeva Steenkamp but will be allowed to travel abroad after challenging his bail terms.
“If he is up for it and qualifies, the World Championships will definitely be on the radar,” Peet van Zyl told AP.
The 14th World Athletics Championships will be held in Moscow from August 10 to August 18.
Oscar Pistorius might consider competing at this year’s World Athletics Championships in Moscow
Oscar Pistorius, 26, nicknamed the Blade Runner because of his prosthetic legs, is accused of murdering his girlfriend Reeva Steenkamp, who was shot and killed at his home in Pretoria on February 14.
The athlete denies murdering the 29-year-old, saying he mistook her for an intruder.
The International Association of Athletics Federations (IAAF), which is the body responsible for the World Championships, said Oscar Pistorius would be “free to run” in Moscow in August on the “basis of the<<innocent until proven guilty>> principle”.
“He’s going to be the one that determines running and training,” Oscar Pistorius’s agent added.
“It’s his call. He’s the one under all the pressure for the court case and grieving for Reeva.’’
Oscar Pistorius must meet certain conditions to be allowed to travel abroad. They include providing an itinerary of his plans at least a week before he is due to leave the country.
The South African was one of the star attractions at the 2012 Olympics in London, becoming the first double amputee to run at an Olympics by taking part in both the 400m and 4x100m.
Oscar Pistorius then won gold medals in the T44 400m and T42-46 4x100m at the Paralympics, as well as silver in the T44 200m.
The International Paralympic Committee said it would discuss the matter of Oscar Pistorius competing again following the Easter break.
