Jones fails to make team in 100

SACRAMENTO, Calif. -- Perhaps it was the stress of fighting doping allegations. Maybe it was the physical and emotional strains of motherhood. Or perhaps time and a new generation of sprinters are finally catching up with her.

Marion Jones failed to qualify for the U.S. Olympic team in the 100 meters Saturday night, losing out on a chance to defend her gold medal in her signature event at the Athens Games.

Jones started quickly but seemed to struggle as the race progressed and finished fifth in the final at the U.S. Olympic trials. The top three finishers automatically make the team.

Jones, who won five medals at the 2000 Sydney Games, still can make the Olympic team if she qualifies in the 200 meters or long jump. Or she could be picked for a relay team.

The defeat comes at a difficult time for perhaps the biggest U.S. Olympic star. Jones, 28, is under investigation by the U.S. Anti-Doping Agency, although she has repeatedly denied using drugs and has not been charged by USADA.

LaTasha Colander won the final in 10.97 seconds, tied for second fastest in the world this year. World champion Torri Edwards was second in 11.02 and NCAA champion Lauryn Williams took the third Olympic spot in 11.10.

Olympic silver medalist Adam Nelson won the shot put with a mark of 71 feet.

Shelia Burrell won the heptathlon.
