None were brighter than the wildly popular Usain Bolt's world record sprint double, and the Jamaican's three gold medals overall. Bolt shattered his own 100 meters mark of 9.69 seconds, set at last year's Olympic Games in China, with a stunning 9.58 on the second night of the WCA. Tyson Gay of the United States finished "second in an American record 9.71, and Jamaica's Asaf a Powell third in 9.84. The 6' 5'' sprint star, who celebrated his 23rd birthday during the WCA, returned days later to the Olympic Stadium track to clock 19.19 in the 200 meters and break his other individual world mark set at the '08 Olympics. That result took [Bolt] more by surprise. In the women's 4x400 relay, Jamaica's team of Rosemarie White, Novlene Williams-Mills, Shereefa Lloyd and Shericka [Gordon Williams] finished second to the U.S. A silver was also earned by Cuba's Yarelis Barrios in the women's discus, while T&T's Renny Quow won bronze in the 400 meters. His country's team of Darrel Brown, Marc Burns, Emmanuel Callander and Richard Thompson, captured silver in the 4x100.
