Maurice Greene was handed yet another defeat in what has been a disastrous season for the world record holder.

But Marion Jones is still on course for a share of the Golden League jackpot.

Jones remains one of four athletes in with a chance of winning a share of the 50kg of gold.

Hicham El Guerrouj, Felix Sanchez and Ana Guevara also all maintained their unbeaten records.

Felix Sanchez left it late in the 400m hurdles

American Tim Montgomery beat Greene for the third week in a row over 100m after he flew down the course in 9.91 seconds.

Greene trailed home in sixth place, just behind Britain's former world junior champion Mark Lewis-Francis.

Portuguese sprinter Francis Obikwelu was second in a national record of 10.01secs with Commonwealth champion Kim Collins third in the same time as Obikwelu.

A late surge for the line saved Jones as she beat Zhanna Pintusevic-Block for the second week in a row over 100m.

The Ukrainian surprisingly beat the American for the world title a year ago.

And she looked to have the race sewn up in the last 10 metres before a last-gasp dip for the line gave Jones victory in 10.88sec.

Jones double

Pintusevich-Block clocked 10.90sec with third-placed Tayna Lawrence of Jamaica running her fastest-ever 100m time of 10.93sec.

Later in the evening Jones completed the double, pulling away from Pintusevich-Block down the straight in the 200m to win in 22.11secs.

The Ukrainian was a tenth-of-a-second behind in second.

In the 1,500m El Guerrouj was pushed by Kenya's Bernard Lagat but pulled away down the home straight to take the win.

Sanchez had to come from behind down the home straight to win the 400m hurdles.

The man from the Dominican Republic celebrated his birthday in style.

He clawed back a metre deficit to win in 47.99sec ahead of European champion Stephane Diagana and American Joey Woody.

Ana Guevara was too strong in the 400m

Before the meeting Sanchez warned that Guevara's record could be under threat from Lorraine Fenton.

But the Mexican kept on track with victory in 49.69, while Fenton was second in 50.17secs.

It was a disappointing night for British athletes, with Olympic champion and world record holder Jonathan Edwards beaten into seventh place in the triple jump.

Edwards could only manage 16.75m, while Phillips Idowu finished fourth.

Marlon Devonish finished fifth in the 200m behind American Coby Miller, who took victory in 20.07secs.

The best British performance came from Jo Pavey on her way to fourth place in the women's 3,000m.

The Bristol runner reduced her personal best by over five seconds as she came home in 8:31.27.
