China's men's 4x100m team sprinted to the third place to wow their countrymen and found out they were upgraded to the second after the US was disqualified for false exchange on Saturday at the world championships in Beijing.

The Americans finished second in the race behind Jamaica but the team was stripped of their place because the last exchange was out of the zone.

Instead of the Americans taking silver, China was moved up to second and Canada took bronze.

China's Mo Youxue, Xie Zhenye, Su Bingtian and Zhang Peimeng clocked 38.01 seconds to finish third. Su made historical cut in the men's 100m final last Sunday to become the first Asian man to compete in championships final with a preliminaries time of 9.99 seconds. Zhang is the continent's second fastest man with a personal best of 10.00 seconds.

The host team started on the ninth lane as Mo and Xie kept pace with the other teams while birthday boy Su improved their position to fourth in the third leg. Zhang edged past Canada's J. Warner in the final meters to ensure a podium finish.

"We have been training very hard to make four people as one. We practiced baton exchange every day since this May."

"This is the moment of life. Can you imagine that 80,000 people sang birthday song to me?" added Su.

Usain Bolt anchored Jamaica to gold at 37.36 seconds to clinch his personal 11th world title.
