Jamaican sprinter Asafa Powell has broken his own world record in the 100 meters, running 9.74 seconds at the Rieti Grand Prix meet in Italy.
Powell's record time, in a qualifying heat, is 0.03 second faster than his previous best - the former world record time of 9.77 seconds, which he has run three times since 2005 , once in 2005 and twice in 2006.
Powell won the final at Rieti Sunday in 9.78 seconds, 0.05 second ahead of countryman Michael Frater.
At last month's World Athletics Championships in Osaka, Japan, Powell finished third as American Tyson Gay won 100 meters gold.
