The United States won its fifth consecutive Olympic gold medal in the women's 1,600-meter relay, easily beating the field Saturday at the London Games.

The American team, anchored by individual 400 champion Sanya Richards-Ross, completed the race in 3 minutes, 16.87 seconds to set a season-best mark. That easily beat Russia's time of 3:20.23, while Jamaica finished .72 seconds later for bronze.

The U.S. team also featured Allyson Felix, DeeDee Trotter and Francena McCorory. Felix was the 200-meter champion here, while Trotter claimed bronze in the 400.

Trotter led off and gave the U.S. a lead it would never relinquish.

While the Americans continued a winning streak that began at the 1996 Atlanta Games, the Russians earned their third consecutive silver and Jamaica won its third straight bronze.
