Elaine Thompson-Herah became the second-fastest woman in history as she retained her Olympic women's 100 metre crown in Tokyo with a Games record of 10.61 seconds.
The Jamaican posted a slightly slower time than reigning world champion Shelly-Ann Fraser-Pryce in the heats but pipped her compatriot in Saturday's incredible final at the Olympic Stadium.
Thompson-Herah's time was just 0.12s short of the all-time women's 100m record set by American Florence Griffith-Joyner.
Fraser-Pryce, who won gold in 2008 and 2012 before claiming bronze in 2016, finished in a time of 10.74 and Shericka Jackson completed a Jamaican one-two-three with a personal best of 10.76.
Six of the eight competitors finished under 11 seconds as one of the most hotly anticipated events of the Tokyo Games lived up to its billing.
