Noah Lyles wins 100m gold in Paris by five-thousandths of a second

After all the talk and all the hype, Noah Lyles delivered when it mattered most by winning the closest-ever Olympic 100 meter final by five-thousandths of a second on Sunday to give the United States the title for the first time in 20 years.

In a photo finish, Lyles believed he had left it too late to catch powerful rival Kishane Thompson, but the giant screen confirmed him as the winner in a personal best 9.79 seconds, the same time as the Jamaican, but ahead by the width of a vest.

If the race had been 99 metres, Thompson would have been celebrating a fourth Jamaican men's 100 meter win in five editions of the Games, but the fast-finishing Lyles kept his form superbly and timed his dip expertly to add Olympic gold to his world title.

He ripped his name bib from his shirt and held it aloft with his red, white and blue varnished fingernails, announcing himself, as he had long promised he would be, as the fastest man in the world.

"It's the one I wanted, it's the hard battle, it's the amazing opponents," said Lyles, the first American male Olympic 100 meter champion since Justin Gatlin in 2004.

"I didn't do this against a slow field – I did this against the best of the best, on the biggest stage, with the biggest pressure."

He was right about that, as it was the first time eight men have broken 10 seconds in a wind-legal 100 meter race.

American Fred Kerley took bronze in 9.81 and Akani Simbini of South Africa was fourth, making it a remarkable six fourth-place or fifth-place finishes in global championships, albeit with the consolation of a national record time of 9.83 seconds.

Defending champion Lamont Marcell Jacobs of Italy, heavily strapped, finished fifth in 9.85 and Letsile Tebogo of Botswana also set a national record of 9.86 in sixth place.

Such was the quality of the race, that eighth-place finisher Oblique Seville of Jamaica clocked 9.91 seconds.

"I did not think I won, I didn't think I dipped at the right time, too early," Lyles said. "I even went up to Kishane while we were waiting and said 'I think you got that one.' But then my name popped up and I thought 'Oh my gosh, I'm amazing'."
