American Fred Kerley stormed to victory in the men's 100-meter to lead a U.S. clean sweep at the World Championships in Oregon on Saturday.

Kerley, in lane four, trailed Marvin Bracy for 95 meters of the tight race but managed to out dip his teammate for victory in 9.86 seconds at Eugene's Hayward Field.

Bracy took silver in 9.88 seconds, Trayvon Bromell claimed bronze with the same time for a third-ever 100-meter world championship clean sweep for the United States after 1983 and 1991.

The fourth of the strong U.S. quartet, Christian Coleman, the reigning world champion from Doha in 2019 who was banned from the Tokyo Olympics for missing three doping tests, finished sixth (10.01) despite an electric start.

"We said we were going to do it and we did! USA, baby!" Olympic silver medallist Kerley said to roars of approval and applause from a partisan home crowd.

"I didn't know until I looked up and saw the clock with my name 'Fred Kerley' on it," added Kerley, whose path to gold was made easier by the withdrawal of Italy's Olympic champion Marcell Jacobs earlier Saturday.

"It means a lot and I've done something not many 400-meter runners have done," Kerley said, adding: "I know today opened up many doors for me. The future is bright for me."

The last U.S. clean sweep featured Carl Lewis, Leroy Burrell and Dennis Mitchell, something not lost on the modest Kerley or silver medallist Bracy.

"It's amazing to be among the great, they did it in 1991, we did in 2022," Bracy said.

"This is history, to be part of something that has only happened three times ever just means the world to me."

Bracy meanwhile paid tribute to Kerley's remarkable versatility. The 27-year-old started his career as a 400-meter specialist before switching down to the shorter 100-meter.

"The guy's special, he's a rare talent to be able to do all three events, his range is limitless. He might do 800m next year, we don't know!

"He's a special cat, amongst an elite group of people like the (Usain) Bolts the Wayde van Niekerk."

Kerley has now set his sights on the 200-meter starting Monday and is also not ruling out runs in the 4x100-meter and 4x400-meter relays.

"If the coach allows me!" Kerley told reporters.

Late-charging Kerley

It was far from plain sailing for the in-form Kerley, who set out his stall with a heat-winning 9.79 seconds on Friday, as all the sprinters got off to a good start.

Bracy and Coleman looked like they might deprive Kerley of a gold many had predicted he would win.

But they hadn't counted on his savage finishing skills, the former 400-meter runner showing all his strength at the line. Bromell also left it late to sneak onto the podium from lane eight.

As the crowd realized it was a U.S. clean sweep, chants of "U-S-A" rang out and flags brandished.

Jamaica's Oblique Seville finished fourth in 9.97 seconds, just ahead of South African Akani Simbine, who was clocked at 10.01 like Coleman in sixth.

Japan's Abdul Hakim Sani Brown and Canada's Aaron Brown were seventh and eighth, in 10.06 and 10.07 seconds respectively.

Failing to advance from the semifinals to the final were Canada's Olympic 200-meter champion, Andre de Grasse, also a two-time 100-meter bronze medallist, and 2011 world champion Yohan Blake of Jamaica.

The build-up to the final was rocked by the decision of Olympic champion Jacobs to withdraw just hours before the semifinals with tightness in his right thigh.

Italian team doctor Andrea Billi said evaluation of the contraction had found a "clinical picture that can put muscle integrity at risk and lead to injury."

Jacobs, who pulled off one of the shocks of the Tokyo Olympics last year when he stormed to victory in the 100-meter in 9.80 seconds, was crowned world indoor 60-meter champion in Belgrade in March but has struggled with injury since.

"I am a fighter and this is why I decided to be in Eugene," he tweeted, saying it had been a "painful choice, I am forced to stop."
