NEWS:Usain Bolt, Jamaica Win 4x100-Meter Relay Gold Medal, Set World Record

Jamaica's Usain Bolt (R) celebrates after he crossed the finish line in first place in the men's 4x100m relay final ahead of Ryan Bailey of the U.S. during the London 2012 Olympic Games at the Olympic Stadium August 11, 2012. The Jamaican team set a new world record of 36.84 seconds

Usain Bolt put an exclamation point on his performance at the London Olympics with another gold medal and another world record.

Running the anchor leg in the men's 4x100-meter relay, Bolt helped the Jamaican team win the gold medal in 36.84 seconds, a new world record. Just days after declaring himself "the greatest athlete to live," the charismatic 25-year-old sprinter went back to work bolstering his argument.

Bolt received the baton from teammate Yohan Blake and then left behind Ryan Bailey of the United States to reach the finish line ahead of the field. The United States won the silver in 37.04 seconds, a new national record. Canada finished the race third but was disqualified, giving the bronze to Trinidad and Tobago.

Nesta Carter ran the opening leg for Jamaica, followed by Michael Frater. Neither sprinter had previously competed during the London Games. The two runners who next carried the baton for Jamaica, however, have made frequent appearances on the medal stand: Blake and Bolt.

Blake finished runner-up to Bolt in the 100 meters and 200 meters before running up behind him during the relay with the baton. After a clean transition, Bolt blew open what had been a tight race between the U.S. runners and Jamaica.
