At the World Championships Chambers finished sixth in 100 m final with a season's best of 10.00 seconds. He was the only sprinter from outside the Americas in the final and was some distance behind Bolt who ran a world record of 9.58 seconds. However, he was very pleased with his performance and said he was happy just to be involved in the fastest 100 m race ever. He pulled out of the 200 m with a calf injury and called an end to his season.
