Usain Bolt has won gold in the 100m finals at the World Athletics Championships in Beijing. He finished the sprint with a time of 9.79 seconds – 0.21 seconds slower than his world record time.
For the first time in many years, Bolt entered Sunday's final as a slight underdog, having recorded a semi-final time of 9.96 seconds compared to the 9.77 of Justin Gatlin of the United States.
But Gatlan, whose reputation in the sport is still in tatters after his drugs ban, settled for silver with a time of 9.80, as Bolt added another title to his name while also ending Gatlin's 28-race unbeaten run at the Bird's Nest stadium.
The Jamaican stumbled slightly on his way out of the blocks, but took full advantage of a nervous-looking Gatlan who staggered through the final 30m. Sunday's win was Bolt's third 100m victory at a world championship, drawing him level with Carl Lewis and Maurice Greene.
"This means a lot because I've been struggling all season, it's taken me a while to work things out," Bolt told BBC Sport.
"It's been up and down but it's OK now."
Andre de Grasse of Canada and young American Trayvon Bromell were both awarded bronzes after finishing with times of 9.92secs.
