ANOTHER US sprinter triumphed in style at the second day of the Aviva Grand Prix at Crystal Palace, but the identity of the winner here was as shocking as Tyson Gay's time yesterday.

Fastest woman in the world Carmelita Jeter was beaten into second place by her US compatriot Marshevet Myers in the women's 100m in a time of 11.01.

Jeter was also beaten in the heats, this time by African champion Blessing Okagbare with a personal best of 11 seconds dead.

Myers had impressed in the other heat with a 10.99 victory, a personal best for her, in testing squally and wet weather conditions.

There was more US success with the massively strong David Oliver posting a meeting record to win the 110m hurdles. European champion Andy Turner couldn't match his heroics in Barcelona, knocking elbows with a runner in the next lane and finishing last.

Other British athletes seemingly suffering a hangover from the Europeans included Christian Malcolm, silver medallist in the 200m in Barcelona, who brought up the rear here with Wallace Spearman of the US gliding to victory.

British 400m medallists Michael Bingham and Martin Rooney came home in fourth and sixth place respectively, with the out-of-form Rooney calling his display an "embarrassment". But it was a very strong field with US runner Jeremy Wariner pipping fastest man in the world this year Jamaican Jermanine Gonzalez.

Double bronze medallist at Barcelona Perri Shakes-Drayton stepped up a class against the world's best in Allyson Felix in the 400m. Felix, already a winner here after yeaterday's 200m, held off a strong efforts from the Russian Tatyana Firova and Debbie Dunn from the US.

Shakes-Drayton continued her fine run of form with a personal best of 51.48.

European bronze medallist Jenny Meadows and Lisa Dobriskey, on the back of a hard 1500m on the first day, went in the 800m. Dobriskey got a personal best but the Brits were left behind by Russian Mariya Savinova in a speedy 1.58 minutes.

Mark Lewis-Francis had a chance to make some amends for the poor baton changeover which scuppered Team Britain's hope of a medal in Barcelona, bringing home the England A team for victory in the 4x100m. The event was a chance to blood possible athletes for the upcoming Commonwealth Games.

Only three-times World Champion Dwight Phillips jumped beyond 8m in the long jump. European bronze medallist Britain's Chris Tomlinson claimed third spot.

The men's discus was won by Estonia's Gerd Kanter with a meeting record of 67.82m.

The South African Bladerunner Oscar Pistorius set a new Paralympic world record for the 400m with a time of 47.04 seconds.
