 On his return from injury a month later , Bolt asserted himself with a 100 m win at the Athletissima meeting in Lausanne ( 9 @.@ 82 seconds ) and a victory over Asafa Powell at Meeting Areva in Paris ( 9 @.@ 84 seconds ) . Despite this run of form , he suffered only the second loss of his career in a 100 m final at the DN Galan . Tyson Gay soundly defeated him with a run of 9 @.@ 84 to Bolt 's 9 @.@ 97 seconds , and the Jamaican reflected that he had slacked off in training early in the season while Gay had been better prepared and in a better condition . This marked Bolt 's first loss to Gay in the 100 m , which coincidentally occurred in the same stadium where Powell had beaten Bolt for the first time two years earlier .
