At the 2009 World Championships in August, Bolt eased through the 100 m heats, clocking the fastest ever pre-final performance of 9.89 seconds. The final was the first time Bolt and Gay had met in the season, and Bolt improved his world record with a time of 9.58 s to win his first World Championship gold medal. Taking over a tenth of a second off the previous best mark, this was the largest ever margin of improvement in the 100 m world record since the beginning of electronic timing. Gay finished with a time of 9.71 s, 0.02 s off Bolt's 9.69 s world-record run in Beijing.
