Fred Kerley led the first American sweep of the 100 meters at the worlds in 31 years Saturday,

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.

Kerley leaned at the line to finish in 9.86 seconds and beat both Bracy and Bromell by .02 seconds.

The difference between second and third was .002.

It marked the first American sweep at worlds since Carl Lewis,

Leroy Burrell and Dennis Mitchell went gold-silver-bronze at the 1991 championships in Tokyo.
