For a brief moment in time, it looked like Jamaica may actually catch the Americans in the 4x400-meter final. But once Allyson Felix took the baton it was elementary.

Felix ran the final leg of the relay on her way to her sixth career Olympic gold medal, good for second most among U.S. women in history.

Felix was joined by her teammates Natasha Hastings, Phyllis Francis and Courtney Okolo in making history in Rio de Janeiro. The Americans finished the race in 3:19.06, besting Jamaica's 3:20.34 time. Great Britain (3:25.88) earned the bronze.

It was the third medal and second gold in Rio for Felix.
