Tobi Amusan became the first Nigerian ever to win gold at the World Athletics Championships after racing to a stunning world record time of 12.06s.
Amusan, who had obliterated the world record in an astonishing semifinal where she clocked 12.12sec, powered over the line at Hayward Field in 12.06sec.
Her winning time will not be recognised as a world record, however, due to a strong following win of 2.5 metres per second.
Jamaica’s Britany Anderson took silver in 12.23sec, while Olympic champion Jasmine Camacho-Quinn of Puerto Rico claimed bronze in 12.23.
Amusan had produced a jaw-dropping world record in the semifinals, smashing the previous best mark of 12.20secs held by Keni Harrison of the United States since 2016.
Honestly, I believe in my abilities but I was not expecting a world record at these championships,” Amusan said after her final victory. “The goal is always just to execute well and get the win. So the world record is a bonus. I knew I had it in me but I could not believe it when I saw it on the screen after the semis.
“Before the final, I just tried to stay calm and to do my best. I took a deep breath knowing that I have some goal to accomplish and it worked pretty good. I knew it was very fast but not this fast.”
Harrison had been left in Amusan’s slipstream in the semi, and was again shown a clean pair of heels by the Nigerian in the final.
Amusan got off to a scorching start and was smoothly into her stride after the first hurdle, building a clear lead and then pulling away ahead of Anderson and the fast-closing Camacho-Quinn.
