Kerley leads U.S. sweep in men's 100m final at athletics worlds as De Grasse fails to qualify

In the place they call "TrackTown USA", American sprinters swept the podium Saturday night in the men's 100-metre final at the world athletics championships.

Fred Kerley was the fastest man of the night in Eugene, Ore., stopping the clock in a time of 9.86 seconds. Marvin Bracy was awarded silver in a time of 9.88 and Trayvon Bromell finished third in 9.88  — a photo finish determined second and third. 

It's the first U.S. sweep in the men's 100 metres at worlds since 1991 in Tokyo.

The crowd went wild as all three Americans made their way around the track after the race, with chants of U-S-A echoing around Hayward Field on an idyllic night for racing.

Canada's Aaron Brown finished eighth in a time of 10.07.

"I got out well and then I messed up the transition. I'm just waiting for my breakthrough. I'm going to keep working at it. This championship isn't over for me," Brown said. 

"People look at me like a 200-metre guy, so to get into this final is encouraging. It bodes well for what I can do in the 200. I'm expecting better things."

Brown, from Toronto, finished third in his semifinal heat, but because of his season-best time of 10.06 seconds grabbed the last spot to qualify for the final.

"It's an honour every time I put on the maple leaf. It's my fifth world championships and it's still exciting; I cherish every moment," Brown said.

"This one I'm especially proud of with my son now."

Brown will now shift his attention to the men's 200m event that goes next week at worlds. 

"Just keep getting better. I'm chasing that podium; I believe I can get there. The grind never stops," he said. 

"More fuel to the fire."
