LONDON (AP) -- The United States and Jamaica advanced to the Olympic final of the women's 4x400-meter relay Friday night.
Both high-profile teams easily won their preliminary heats. With 400 bronze medalist DeeDee Trotter running the anchor leg after Keshia Baker, Francena McCorory and Diamond Dixon circled the track, the Americans finished in 3 minutes, 22.09 seconds.
Jamaicans Christine Day, Shereefa Lloyd, Shericka Williams and Rosemarie Whyte won the opening heat in 3:25.13.
Russia, Britain, Ukraine, France, the Czech Republic and Nigeria also qualified for Saturday night's final.
The Americans have won the last four Olympic golds in the event. Sanya Richards-Ross, the gold medalist in the 400, is expected to join the U.S. squad in the final.
