Bolt makes history with 200m victory at London Olympics

Usain Bolt claimed an historic victory in the 200 meters at the London Olympics Thursday as he completed the sprint double for the second time.

Bolt became the first man in Games history to defend both the 100 and 200 meters titles 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 claim the silver medal.

Warren Weir completed a one-two-three for Jamaica in a personal best time of 19.84 seconds.

Bolt was just 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.

Both men are coached by Glen Mills.

An epic night was kick started by a sensational victory in the men's 800m for David Rudisha of Kenya.

Jamaica's sprint pedigree

Rudisha ran one minute 40.91 seconds to break his own world record, the first in the track and field events at the Games.
