Defending champion Elaine Thompson-Herah led home a Jamaican clean sweep in the Olympic women's 100 metres final on Saturday.
She posted an amazing 10.61 seconds to become the second-fastest woman in history.
Shelly-Ann Fraser-Pryce, who had been seeking a third gold in the event, took silver in 10.74 with Shericka Jackson third in 10.76.
Thompson-Herah's Olympic record time has been beaten only by Florence Griffith-Joyner's 1988 world record of 10.49 - though the American also ran a 10.61.
