The United States is out of the women's 4x100-meter relays following a botched handover between Allyson Felix and English Gardner on the far side of the track.
Felix seemed to stumble as she entered the exchange zone and could not catch third runner Gardner, flipping the baton in desperation. It hit the ground as Gardner and Felix crashed into each other. Gardner held her head in desperation as Felix went to pick up the baton and hand it over.
The U.S. team did finish the race as last. At the same time Jamaica easily won their first heat. The Dutch team was also out.
