The current fastest guy in the world is Fred Kerley

Fred Kerley did not know that he was the fastest man in the world

when he finished the race on Saturday night at Hayward Field

He had to wait and wonder, just like so many other things in his life

He didn't realise he had won gold until the No. 1 and his time of 9.86 seconds appeared next to his name

“I got the job done,” said Kerley, a man who is efficient with both his strides and his words

Kerley, a former 400-meter specialist for whom none of this — acclaim

gold medals, world championships — was foreshadowed when he was growing up
