Williams came home in 10.11 seconds, ahead of Montgomery in 10.15s and Jon Drummond in 10.18s.

The three qualified for August's World Athletics Championships in Paris.

"I was confident going into the race," said Williams. "I had to make myself believe I could win and visualize it so it was like a premonition.

"I was hungry, I reacted well, I had good transition and I maintained the top end as long as I could."

Montgomery, who claimed the world record with a 9.78s run in Paris last September, had earlier looked unimpressive despite winning his semi-final.

"My stride was choppy in the semi-finals, so I told myself I was going to lengthen my stride and I lengthened it, but I couldn't hold it," said Montgomery, who stumbled leaving the blocks.

Maurice Green did not have to qualify because he is granted an automatic entry as the reigning world champion.

Greene is trying to qualify in the 200m in a bid to pull off a sprint double.

In the women's 100m, Kelli White won with a scorching personal best of 10.93 seconds.

Torri Edwards was second in 11.13s with 36-year-old Gail Devers, a two-time Olympic gold medalist in the 100m, third in 11.16s.

White's run eclipsed her previous best of 10.95s set at this year's Prefontaine Classic, giving her the two fastest times in the world this year.

"I think I'm just learning how to run and how to compete," she said.

White also goes in the 200m, where she will face 17-year-old Allyson Felix and 31-year-old former world champion Inger Miller.

The top three in each event make the US team for the world championships.

Other men's winners on Friday included Jamie Nieto in the high jump, Dwight Phillips in the long jump, James Parker in the hammer, and Tim Broe in the 5,000m.

Other women's winners were Kristin Heaston in the shot put, Erica Wheeler in the javelin and Shelia Burrell in the heptathlon.

Marla Runyan, who is legally blind, won the national title in the 5,000m for the third straight year.
