Bolt wins 11th Worlds gold, China picks relay silver

Usain Bolt anchored Jamaica to the world 4x100 metres relay title -- his 11th in the World Athletics Championships here on Saturday.

Bolt ran the final leg at a packed Bird's Nest National Stadium, leading his country to the winning time of 37.36 seconds after Nesta Carter, Asafa Powell and Nickel Ashmeade had perfect baton exchanges, reports Xinhua.

China claimed a historic silver medal in 38.01 seconds and Canada won the bronze medal in 38.13 seconds.

The United States foursome of Trayvon Bromell, Justin Gatlin, Tyson Gay and Mike Rodgers finished second behind Jamaica, but they were stripped of their place because the third and final baton exchange was out of the zone.
