BEIJING (AP) - Usain Bolt has become the ninth male sprinter to sweep the 100 and 200 gold medals at a single Olympics, and the first to do it in world-record time.
The Jamaican completed the feat with a run of 19.30 seconds in the 200, shaving two-hundredths of a second off the old mark set by Michael Johnson at the 1996 Atlanta Games.
Bolt's performance comes four days after he bettered his own world record in the 100.
Usain beat Americans Shawn Crawford and Walter Dix.
Crawford was bumped up to a silver medal and Dix received a bronze after Churandy Martina was disqualified for running into another lane.
