MEXICO CITY, May 14: Former Olympic sprint queen Marion Jones ran the year's second fastest 100 metres on her seasonal debut, clocking 11.06 seconds to defeat ex-world champion Torri Edwards at Veracruz, Mexico on Saturday.

The race was the 30-year-old American's first appearance in 11 months and produced her fastest time since 2004.

Despite registering a morale-boosting victory, the triple gold-medal winner at the 2000 Sydney Olympics crossed the line more than four-tenths of a second off her personal best of 10.65 seconds set in 1998.

Edwards finished a distant second in 11.30 seconds although the sprinters did run into a headwind.

America's world 200 metres champion Allyson Felix has the year's quickest time of 11.04 seconds.

Jones, who is hoping to re-establish herself as a world-class sprinter, has suffered a slump in form since giving birth to her first child with then-partner Tim Montgomery in June 2003.

The couple separated last year and Montgomery was banned from the sport for two years and stripped of his 100 metres world record in December by the Court of Arbitration for Sport (CAS).

The court made its ruling on the basis of evidence accepted from the US Anti-Doping Agency (USADA) that he had taken banned substances provided by California laboratory BALCO.—Reuters
