SACRAMENTO (California): Olympic champion Marion Jones has failed to make the 100m team for Athens after she could only finish fifth in the US trials on Saturday.
Looking short of her trademark explosive power, Jones clocked 11.14 as the field pulled away in the final third of the race.
Only the top three finishers are guaranteed a place in the team for next month's Games providing they have met the Olympic qualifying standard.
Jones's former teammate LaTasha Colander won the race in a personal best of 10.97.
The time equalled the second fastest in the world this season.
World champion Torri Edwards was second in 11.02 and collegiate winner Lauryn Williams took third in 11.10.
Jones, who has been under scrutiny by the US Anti-Doping Agency (USADA) although she has never failed a doping test, will now attempt to qualify in the 200m and long jump.
At the Sydney Games, she won gold in the 100, 200 and 4x400m relay and took bronze in the long jump and 4x100m relay.
Jones left the track without answering any questions from awaiting reporters.
When I talk, you guys have something negative to say.
When I don't talk, you have something negative to say, she said as she hurried away.
I'd rather not talk and spend the time with my son.
Jones' boyfriend and the father of her son, world 100m record holder Tim Montgomery, and Olympic champion Maurice Greene were among those making it through the first two rounds of the men's 100m.
Greene won his quarter-final in 10.06.
Montgomery, who faces a lifetime ban after being charged with a doping offence by the USADA, qualified fourth in a later race at 10.16.
