US women led its gold rush on the final day of the World Athletics Championship in Doha with a 4 x 400m relay romp and a standout victory for Nia Ali in the women's 100 m hurdles.
The successes took the US to a tally of 14 gold and 29 medals in total, well clear of Kenya and Jamaica in the medals table for the 10-day championship in the Gulf state.
Dalilah Muhammad, who set a world record in the women's 400m hurdles final on Friday, ran a blistering third leg of the 4 x 400 to win her second gold of the meet with Poland a distant second and Jamaica third.
