OREGON: USA extend dominance in 4x100m

The United States continued their dominance in the women's 4x100m as Kaylin Whitney anchored her team win finishing at 43.46, the eighth-fastest junior time in history and the third quickest in the history of the World Junior Championships. Teahna Daniels put the US team in the lead after the first exchange, ahead of Jamaica, Germany and Trinidad and Tobago. The host squad relied on their individual sprint finalists Ariana Washington and Jada Martin to set the pace, before Whitney secured her country's ninth world junior title in the event and the sixth consecutive one since 2004.
