Athens, Greece ? Two decades of American dominance in the 100 meters ended Saturday when Yuliya Nesterenko rode a powerful closing surge to overtake Lauryn Williams, nipping the newest American track standout at the finish.

Nesterenko, a Belarusian who had never broken 11 seconds before the Olympics but did it in all four rounds here, won gold in 10.93 seconds. Williams, the NCAA champion from the University of Miami, was second in a personal-best 10.96. Veronica Campbell of Jamaica got the bronze in 10.97.

Nesterenko went out to an early lead, then Williams overtook her with about 30 meters remaining. But the taller Nesterenko used her longer stride to catch the 5-foot-3 Williams in the closing meters.

Silver was just fine for Williams, a talkative 20-year-old who just a few months ago was taking college classes. It was made sweeter by the presence of her father, who has leukemia and came to Athens after a $10,000 donation from a cancer survivor in his home state of Pennsylvania.

Earlier Saturday, Stacy Dragila failed to make it out of pole vault qualifying, a shocking performance by the medal favorite and former world record holder.

Dragila, who won the vault when it debuted as a women’s event at the 2000 Olympics, missed three attempts at 14 feet, 51/4 inches (4.40 meters), well below her best of 15 feet, 10 inches (4.83). After her third miss, she shook her head in dismay, seemingly stunned. Then she slowly packed up her gear, put on a cap and headed off the field.

Healthy at last, Justine Henin-Hardenne is back at the top of her game. And she has a gold medal to prove it.
