LONDON -- Two-time defending champion Veronica Campbell-Brown of Jamaica barely advanced out of the opening round of the Olympic 200 meters, finishing third in her heat in 22.75 seconds Monday night.

Sanya Richards-Ross, running less than 24 hours after winning the first U.S. gold in track and field, turned in the fastest 200 heat at 22.48.

Richards-Ross took it easy early, was fourth with about 50 meters left, then picked it up at the end.

Americans Carmelita Jeter, the silver medalist in the 100 on Saturday, and Allyson Felix, the runner-up in the 200 at each of the past two Olympics, also qualified. So did the other two Jamaicans in the field: two-time 100 champion Shelly-Ann Fraser Pryce and Sherone Simpson.

The semifinals are Tuesday, the final Wednesday.
