Tyson Gay (born August 9, 1982) is an American track and field sprinter who competes in the 100 and 200 meters dash. His 100 m personal best of 9.69 seconds is the American record and makes him tied for the second fastest athlete ever. His 200 m time of 19.58 makes him the sixth fastest athlete in that event.
Gay has won numerous medals in major international competitions, including a gold medal sweep of the 100 m, 200 m and 4 × 100 m relay at the 2007 Osaka World Championships. This made him the second man to win all three events at the same World Championships, after Maurice Greene (Usain Bolt duplicated the feat two years later). Gay is a four-time U.S. champion in the 100 m.
At the 2008 Olympic Trials, he ran a wind assisted 9.68 seconds in the 100 m. Days after he suffered a severe hamstring injury in the 200 m trials and did not win any medals at the Beijing Olympics. His performance of 9.71 seconds to win the 100 m silver medal in the 2009 World Championships is the fastest non-winning time for the event.
In July 2013, it was announced that Gay had tested positive for a banned substance, following which he withdrew from consideration for the World Championships in Moscow. The United States Anti-Doping Agency (USADA) suspended him until June 23, 2014, and stripped him of his silver medal in the 4 × 100 m relay from the 2012 Summer Olympics as a result.
Gay is a two-time winner of the Jesse Owens Award, was the 2007 IAAF World Athlete of the Year, won Best Track and Field Athlete for Track & Field News in 2007 and for ESPY Award in 2008 and 2011. He has also achieved multiple Mens seasons best performances in the 100 m and 200 m.
