Usain Bolt carved his name in the Olympic record books Thursday by
claiming gold in the 200 meters in London as he led a Jamaican sweep of
the medal positions.
The 25-year-old Bolt
became the first man in Games history to defend both the 100 and 200
meters titles, which he had won in such convincing style at the 2008
Olympics in Beijing.
His teammate and training partner Yohan Blake chased him all the way up the finishing straight to take the silver medal.
Warren Weir completed a one-two-three for Jamaica in a personal best time of 19.84 seconds.
Bolt was outside his own world record with a winning time of 19.32 seconds, while Blake clocked 19.44 seconds.
Wallace Spearmon was fourth for the United States.
The 25-year-old Bolt won the 100m final Sunday in 9.63 seconds, again relegating Blake to second place.
