Dispelling two years of injury doubts, the Jamaican won three sprint gold medals last week for an overall world championship record of 11. The last of them came on Saturday when he anchored the 4x100-meter relay team with free-flowing, giant strides that have made him an icon for the sport. Behind him, the United States was far back in second place. But Justin Gatlin, who had been unbeaten in two seasons of sprinting, lost the chance for a third silver when the American team was disqualified for a bad exchange on the anchor leg.
“I saw the mess after 300 meters and was happy we were not in it,” Bolt said.
