Ky Westbrook (Chandler, Ariz.) ran a lifetime best into a slight headwind (-0.8) to win her first international medal and Team USA’s first gold medal of the championships. Westbrook is the daughter of former NFL wide receiver Michael Westbrook who played for the Redskins and Bengals. Ariana Washington (Signal Hill, Calif.) out-leaned Angela Tenorio of Ecuador at the line to take the silver by one hundredth of a second in 11.40.
USATF forgot to mention her time. 11.33 into a 0.8 m/s wind.
