The Jamaican sprinter wins gold with a time of 19.30 seconds. He is the first person to break both the 100 and 200 world records in the Olympics.

He won the Olympic 200 meters in 19.30 seconds, breaking Michael Johnson's seemingly untouchable world record of 19.32 seconds.

The time was even more startling since it was run into a headwind of about 2 mph.

Churandy Martina of the Netherlands Antilles was second in 19.82. Wallace Spearmon of the United States was disqualified for a lane violation after finishing third in 19.95 but did not know as he took a lap of honor with the flag. The DQ moved defending champion Shawn Crawford of the U.S. up to the bronze in 19.96.

Bolt defied predictions, his own pre-race feelings of tiredness and all the past norms of sprinting, blasting into the lead soon after the gun, winning the race in a rout and then flopping onto his back on the curve after the finish line.

The stadium loudspeakers then repeatedly played "Happy Birthday" for Bolt, who turns 22 Thursday.

Unlike the 100, when he set a world record despite sashaying through the final 20 meters, Bolt ran all the way to the line and leaned at the finish.

He became the first person to break both the 100 and 200 world records in the Olympics.

Winning the 100-200 double at the Olympics is not rare. Eight other men have done it (five before World War II, including Jesse Owens, and three after), but the most recent was Carl Lewis in 1984.

The thought that Bolt could be first to break another world record is what heightened the anticipation for Wednesday's final, especially since no one has been near the 200 record since Johnson set it at the 1996 Olympics.

U.S. runner Tyson Gay had the next-fastest time in history, a 19.62 at last year's national championships. Gay injured himself trying to qualify for the 200 at these Olympics. Most, including Johnson, felt the record would be standing after Wednesday's final.

"I don't think he will break it here," Johnson said Wednesday, "but I wouldn't be shocked or surprised [if he did]. In order to run 19.30, he has to run the curve better and hold his speed for longer.

"I didn't think he would run 9.69 [in the 100], but I think he could have run 9.62 if he had run to the finish and tied up his shoes."

Four-time Olympic medalist and NBC commentator Ato Boldon predicted a 19.39.

Stephane Caristan, a Eurosport commentator and former European champion in the high hurdles, felt the time would be between 19.4 and 19.5.
