Justin Gatlin flew out to a fast start and held off Tyson Gay to win the 100 meters in the U.S. Olympic trials.
Gatlin, the 2004 Olympic gold medalist, finished in 9.80 seconds, beating Gay by 0.06 seconds Sunday night.
Ryan Bailey was a surprise third-place finisher as he edged 2009 U.S. champion Mike Rodgers, savvy veteran Doc Patton and Walter Dix, the Olympic bronze medalist in Beijing. Dix pulled up in the semifinals with a left hamstring injury and wasn't the same in the final.
Gay proved he was back after missing almost a year as he recovered from a hip injury that required surgery. Gay is the American record holder in the event.
