Jones is one of the athletes under scrutiny of USADA

The three-times Olympic champion, who is under scrutiny by the US Anti-Doping Agency but has not been charged, said "she just didn't have it" on the track.

She clocked 11.12 seconds to finish well behind winner Inger Miller.

"I would love it if there weren't those distractions but it is the hand I was dealt and I have to deal with it. That's what I am doing," added Jones.

The American performed better in the long jump, winning with a leap of 6.93 metres.

At the same meeting, Maurice Greene was also beaten by Shawn Crawford, who clocked the year's fastest 100 metres in 9.88 seconds.

"I just couldn't catch him," said Greene.

World record holder Tim Montgomery, Jones's partner, was a disappointing sixth in 10.17 seconds.

Afterwards, Jones said she did not see a quick end to the investigation of her by the US Anti-Doping Agency.

"I see it going through the trials and probably right up to the Games," she said.

"I would love for it to have been done yesterday, and for it to be done tomorrow, but it just seems that this organisation is dragging its feet."

Commonwealth champion Kelly Holmes was beaten into second place over 1,500m by Yelena Zadorozhnaya.

The British Olympic medal hopeful failed to match the finishing speed of Russia's European bronze winner.

Zadorozhnaya won in a time of four minutes 2.15 seconds with Holmes posting a season's best 4min 03.73sec in front of Canada's Malindi Elmore (4:04.06).

Holmes' who recently ran 4:04.18 for third in the Ostrava Super Grand Prix, again bettered the Olympic qualifying standard.
