World champion Tyson Gay ran the fastest 100 metres of all-time on Sunday, a wind-assisted 9.68 seconds to win the American trials.
The victory put Gay into his first US. Olympic team but the wind speed of 4.1 metres per second deprived the 25-year-old of a world record.
Only marks set with assisting winds of 2.0 metres per second or less can be considered for record purposes.
Jamaican Usain Bolt holds the world record of 9.72 seconds.
Obadele Thompson of Barbados had the previous best under any conditions, a wind-assist 9.69 seconds in 1996.
Walter Dix (9.80 seconds) and Darvis Patton (9.84 seconds) also made the U.S. team.
