Dwain Chambers: Could manage only sixth in the 100 metres in Puerto Rico on Saturday
Dwain Chambers came home a disappointing sixth at the Ponce Grand Prix in Puerto Rico on Saturday in his first 100 metres race since being cleared to compete at this summer's London Olympics.
Trinidad & Tobago's Keston Bledman claimed victory in 10.12 seconds, with Jamaica's Nickel Ashmeade second in 10.15secs and American Trell Kimmons third (10.18).
However, Chambers, 34, was well back as he clocked 10.52 and was also beaten by fellow Briton Tyrone Edgar, who finished fourth in 10.42.
Chambers, who was banned for two years in 2004 after testing positive for a banned steroid, was prevented from participating at the Beijing Games but is eligible for selection for London after the British Olympic Association's lifetime ban for drugs cheats was last month ruled non-compliant by the Court of Arbitration for Sport.
Elsewhere at the meet, Cuba's Dayron Robles - the reigning Olympic champion and world record-holder - could manage only fourth in the 110-metre hurdles.
American Ryan Wilson won the race in 13.42 seconds as the US swept the podium places with Jason Richardson second in 13.43 and David Payne third in 13.45.
Robles, who was using the event as preparation for this summer's Olympics, is now expected to compete in Diamond League events at Eugene, Oregon, and New York next month.
