MADRID (AP) -- Justin Gatlin edged Dwain Chambers to win the 100 meters at a meet in Madrid on Saturday, notching a confidence-boosting victory ahead of the upcoming world championships.
The former Olympic champion finished in 10.10 seconds running into a headwind to beat Chambers of Britain and fellow American Travis Padgett.
Gatlin returned to competition last year after serving a four-year ban for a second positive drug test. He won Olympic gold in 2004 and world titles in the 100 and 200 one year later.
His second-place finish at the United States Championships last month qualified him for the worlds in Daegu, South Korea, Aug. 27 to Sept. 4.
