Justin Gatlin tore up Usain Bolt’s farewell script as he stole world 100m gold with the run of his long and controversial career.
Bolt was left with only a bronze in his final individual 100m race as 21-year-old Christian Coleman made it a USA one-two.
The 35-year-old Gatlin, twice banned for doping, came through almost unnoticed in lane seven in 9.92 seconds, with Coleman’s 9.94 holding off the greatest sprinter of all time.
Despite struggling for fitness and form in his valedictory season, Bolt had still been favourite to secure his 20th global gold.
It was supposed to be Gatlin’s year in 2015, when the American went to the World Championships in Beijing on the back of a 28-race unbeaten run.
Bolt produced his great miracle to beat him that night in the Bird’s Nest, but in the stadium where he won 100m Olympic gold in 2012, he could not provide the perfect ending to a perfect career.
Gatlin takes his revenge
Gatlin, double Olympic champion in Athens in 2004, had been booed every time he went to his blocks at these championships, his doping past making him the cartoon villain of a troubled sport.
He was to have his revenge in spectacular style, standing tall and putting a furious finger to his lips as his win stunned the capacity crowd.
The crowd at the stadium took a little revenge of their own, chanting, “Usain Bolt! Usain Bolt!” as the result began to sink in.
But this was a deserved victory in its execution if not its formation, a last hurrah for a man that many in the sport wished no longer had the chance to compete.
Ayana adds world gold as Manyonga takes long jump
Olympic champion and world record holder Almaz Ayana put a problematic season behind her to storm to 10,000m gold.
Ayana, who set that staggering record a year ago in Rio, threw in a decisive injection of pace at halfway to finish 45 seconds clear of her Ethiopian compatriot Tirunesh Dibaba in 30 minutes 16.33 seconds, with Kenya’s Agnes Tirop taking bronze.
Luvo Manyonga completed a fairytale triumph in the long jump as his second-round leap of 8.48m took gold from the USA’s Jarrion Lawson by four centimetres, as the winner’s fellow South African Ruswahl Samaai was third.
Manyonga, a former crystal meth addict, celebrated in style after going one better than his silver in Rio.
Lithuania’s Andrius Gudzius, with a final round of 67.89m, took discus gold from Sweden’s Daniel Stahl and the USA’s Mason Finley.
Britain’s Laura Muir qualified impressively for Sunday’s 1500m final as she was second in her semi-final.
Muir will be joined by compatriot Laura Weightman, who came storming through down the home straight.
