Jamaica's Bolt wins 100 in world record time

Jamaica's Usain Bolt ran to another world record Sunday, winning the 100-meter race in 9.58 seconds at the world championships. Bolt shaved .11 seconds off the record he set at the Beijing Olympics, beating defending champion Tyson Gay, who set a US record of 9.71 seconds. In the fastest 100 ever, Asafa Powell took Jamaica's second medal, a bronze with a time of 9.84. The race had been the most anticipated event of the world championships and lived fully up to its billing. Bolt won the Olympic gold in Beijing last year with a world record performance of 9.69.
