They needed a do-over to reach Friday's final of the women's 4x100-meter relay, but the U.S. made it count with a gold-medal finish in Rio.
The team ran the race with a time of 41.01. Jamaica won the silver and Great Britain won the bronze.
The American women, considered medal favorites in the event, initially did not advance to the final from Thursday's qualifying when Allyson Felix dropped the baton after being bumped by a Brazilian runner who crossed into her lane.
Felix eventually picked up the baton and passed it to teammate English Gardner as the team finished the heat in last place. However, a successful protest landed them a second chance.
Running by themselves in their own qualifying heat on Thursday night, the U.S. posted the fastest overall time at 41.77 seconds to earn a spot in the finals while Brazil was disqualified.
Felix also was a member of the U.S. team that won gold in the event at the 2012 Olympic Games, one of three golds she won in London.
