Summary
Olympic champion Dalilah Muhammad (USA) duplicated her strategy by running aggressively from the start of the final, making up the stagger on Léa Sprunger (SUI) to her outside during the first turn and passing two-time defending champion Zuzana Hejnová (CZE) another lane over by the third hurdle. The closest to keep pace with Muhammad was Kori Carter (USA) almost unnoticed out in lane 9. By the time they arrived on the home stretch, Muhammad had a step on Carter, with Hejnová another two steps back. But Carter closed quickly, passing Muhammad before the final hurdle and running powerfully to the finish for the win. Also closing fast from two steps behind, Ristananna Tracey (JAM) caught Hejnová over the tenth hurdle and widened the gap for a clear bronze.
