Lyles lands another 200m world title to complete sprint double

American Noah Lyles stormed to his third consecutive world 200 metres title and became the first man to win the sprint double since Jamaican great Usain Bolt in 2015.

Five days after capturing his first world title in the 100m, the 26-year-old Lyles pulled away down the straight to win in 19.52 seconds, just shy of his world-leading time of 19.47.

US team-mate Erriyon Knighton, bronze medallist at last year's worlds, upgraded to silver in 19.75, while Letsile Tebogo of Botswana, second in the 100 final, took bronze in 19.81.

Olympic champion Andre De Grasse of Canada was sixth.

Jamaica's Shericka Jackson delivered a command performance to retain her world 200 metres title in 21.41 seconds – the second-fastest time ever run.

Jackson, second in the 100m final, ran a brilliant bend, was two metres clear coming into the home straight and tore home to win by a street. Only Florence Griffith-Joyner's 21.34 world record from 1988 is faster.

Gabby Thomas took silver in 21.81, while fellow American Sha'Carri Richardson added bronze to her 100m gold with a personal best 21.92.
