Noah Lyles captured the 100-meter world championship by finishing in 9.83 seconds for a victory that reshuffled the deck for next year’s Olympics and cements him as the world’s No. 1 sprinter.

Fred Kerley led the first American sweep of the 100 meters at the worlds in 31 years, barely edging teammates Marvin Bracy and Trayvon Bromell to stamp a red-white-and-blue exclamation point on the first championships ever held in the United States.
