Shelly-Ann Fraser-Pryce won a record fifth women's 100m world title in a Jamaican clean sweep of the medals as Dina Asher-Smith finished fourth.
The 35-year-old defended her 2019 crown in Eugene and ran a championship record of 10.67 seconds to finish ahead of Shericka Jackson and Elaine Thompson-Herah, who took silver and bronze respectively.
She is the first to win five world titles in an individual track event.
It is the first time a nation has taken a clean sweep of the women's 100m medals at a World Championship, and comes a day after the United States completed the one-two-three in the men's 100m final.
The same Jamaican trio achieved the feat at last year's Olympics in Tokyo - Thompson-Herah winning her second gold on that occasion - with the nation also doing it at the 2008 Games in Beijing.
