The disgraced American sprinter Justin Gatlin has taken another step towards resurrecting his career by edging out former world record holder Asafa Powell of Jamaica in the 100 metres at the Diamond League opening meeting in Qatar.
Gatlin, who's making a comeback after a four-year doping ban, ran 9.87 seconds.
The 2004 Olympic 100 metre gold medallist has a great record of competing in Doha, where he equalled Powell's then-world record of 9.77 seconds in 2006.
The record was later rescinded after his doping violation.
The Jamaican sprint star Usain Bolt was absent from the meet, preferring to make his season debut in at home last week.
