Daegu: The United States maintained their grip on the women`s 4x400 meters crown on Saturday with their third consecutive world championships victory.
The U.S. quartet of Sanya Richards-Ross, Allyson Felix, Jessica Beard and Francena McCorory crossed the line in three minutes 18.09 seconds, with Jamaica holding off Russia to take the silver medal.
Richards-Ross, who finished a disappointing seventh in the individual 400 final, staked the United States to a good lead on the first leg and they were never threatened.
"It was a great team effort and I`m really happy to represent the United States," Richards-Ross said.
The gold was also the first of the competition for Felix, who had been targeting an unprecedented world 200-400 double but had to settle for silver and bronze.
