BOLT SETS RECORD TO WIN 100M GOLD

The 22-year-old Jamaican recorded a time of 9.58 seconds to shave 0.11 off the mark he set last year when winning gold at the Beijing Olympics. American Tyson Gay was second in a time of 9.71, with Jamaica's Asafa Powell claiming bronze in 9.84. Britain's Dwain Chambers came sixth in a season's best time of 10.00. Bolt, who set three world records when winning his Olympic golds in Beijing last summer, served up another superlative display to enhance his reputation as the best sprinter of all time. In the final, he powered out of the blocks at the first time of asking and took control of the race within the first 30m, the crowd going wild as he streaked across the line. Bolt's time represents the biggest increase in the record since electronic timing was introduced in 1968. "I was ready, I was feeling good after the semi-finals," Bolt told BBC Sport. "I knew it was going to be a great race and I came out and executed it. It's a great time. I did well and I feel good in myself." Former world record holder Powell paid tribute to his compatriot, saying: "When I saw the time I had to try and catch him, but I couldn't." Gay, who went into the final as the reigning world champion, has been troubled by a nagging groin pain and had to cut practice on his start.
