race at the 2009 US championships in June, running a windy 9.92 seconds. This won him a place on the American team for the 2009 World Championships in Athletics. Prior to the event, he was runner-up in Monaco and in Stockholm – running a wind-assisted 9.95 seconds behind Tyson Gay at the latter. He managed to reach the final of the men's 100 meters after scoring a season's best of 9.98 in the semi-finals. He performed poorly in the final however, finishing last with a slow time of 10.34 seconds due to an injury. The hopes of the American men's relay team were again dashed by an illegal baton exchange, this time between Patton and Shawn Crawford. Patton ended his season on a high: he ran a series of sub-10 runs including 9.95 for third at the Weltklasse, 9.94 to win the Hanžeković Memorial, and a personal record-equalling run of 9.89 seconds for third at the Shanghai Golden Grand Prix, behind Tyson Gay and Asafa Powell. He also placed third in the 100 m at the Memorial Van Damme and the 2009 IAAF World Athletics Final. Second Olympic medal Patton's 2010 season was brought to an end in May due to another injury. He returned in 2011 and began racing more frequently in the 200 m. At the 2011 USA Outdoor Track and Field Championships he was sixth in the 100 m but managed second place to Walter Dix in the 200 m. The 2011 World Championships in Athletics was one of his less successful global outings. He was eliminated in the 200 m semi-finals and in the relay final he clashed with Britain's Harry Aikines-Aryeetey and failed to pass the baton successfully. He had season's bests of 9.94 seconds for the 100 m and 20.25 seconds for the 200 m. The 2012 United States Olympic Trials he placed fifth in both the 100 m and 200 m. Although he had failed to gain an individual spot, he was chosen for the relay team. At the 2012 London Olympics he ran as a substitute runner in the qualifiers but even the weaker American team of Jeff Demps, Patton, Trell Kimmons, and Justin Gatlin broke the national record of 37.38 seconds. The American team for the final (bringing in Tyson Gay and Ryan Bailey) improved that record further to 37.04 seconds but was still second behind the world record-breaking Jamaican team.
