Allyson Felix set up a showdown with Sanya Richards-Ross and Jeneba Tarmoh by advancing to the final at the women's 200 meters Friday at the U.S. Track & Field Olympic Trials.

Richards-Ross, a two-time Olympic gold medalist and the 400-meter bronze medalist in Beijing, had the fastest qualifying time by winning her heat in 22.15 seconds. Felix, a three-medal winner at the Summer Games, was first in her semifinal, as was the 22-year-old Tarmoh, both with times of 22.30 seconds.

"I was pleased to see that time. Hopefully tomorrow I'll go even faster and put together another great race to win it," Richards-Ross said.

The final is Saturday night.

Emma Coburn won the women's 3,000 meter steeplechase. She ended the race in 9 minutes, 32.78 seconds, just ahead of Bridget Franek and Shalaya Kipp. All three made it to the Olympics for the first time.

"I've had this goal since last year," Coburn said. "This was a goal that I was hungry to receive. It'll be great to run in London with these girls."

Jillian Camarena-Williams won the women's shot put with a toss of 19.16 meters. Michelle Carter and Tia Brooks also secured an Olympic berth.

Hyleas Fountain, the 2008 Olympic silver medalist, ended Friday in first place after four events of the women's heptathlon.

Lashinda Demus had the fastest time in the semifinals of the women's 400-meter hurdles, while the men's event saw two-time Olympic champion Angelo Taylor with the quickest time heading into the final.
