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 at the world athletics championships.

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."

"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.

Brown will now shift his attention to the 200m event that goes next week at the world championships. 

"Just keep getting better. I'm chasing that podium. I believe I can get there. The grind never
