6. Junior Women's 4x400m relay takes down Team Jamaica
The Team USA junior women's 4x400m relay clocked a U20 world-leading time of 3:34.64 in the prelims only to be one-upped by Jamaica in the next section as they ran 3:33.18 to make short work of their heat.
For the final, the U.S. added Lynna Irby, the 400m silver medalist, and Anna Cockrell, the 400m hurdles gold medalist, to the lineup that already included Karrington Winters and Sammy Watson.
Irby handed off evenly with Jamaica, and then Cockrell faced 400m gold medalist Tiffany James, who ran 51.32 to win on Thursday. Cockrell split about 51.0 to close the gap. Winters, the third leg, blew the race open ahead of the Jamaicans to safely hand off to Watson, who closed in about 52.47 for a time of 3:29.11 over Jamaica's 3:31.01.
