In the showboating, smack-talking world of professional sprinting, Fred Kerley has always been something of an outlier. He does not pound his chest as he steps into the blocks. His news conferences rarely make news. He often ends social media posts with the hashtag "#SayNoMore."
He certainly didn't need to say much Saturday night.
A little less than a year after winning silver at the Tokyo Olympics, Kerley squeaked across the line in the men's 100-meter final at Hayward Field to win his first world championship — and lead the first American sweep in the event since 1991.
