DES MOINES, Iowa – The Olympic Champion Dalilah Muhammad crushed the star-studded field and the history of the Toyota 2019 USATF Outdoor Championships in the 400m hurdles. Muhammad had a quick start and was even with Shamier Little in the first half of the race and then retired on the turn of all. When she reached the home straight and crossed the penultimate ninth hurdle, Muhammad had almost a full second lead on the field, which included the four fastest women in the world this year. As she crossed the line, the time flashed from 52.1
7 (corrected to 52.20) on the scoreboard. Muhammad gave a smile and then clapped once. She had broken Yulia Pechonkin's nearly 16-year world record of with 52.34 years. The record finished the season with 52.88 as the second, and Ashley Spencer took home a 53.11 PR in third to win the Doha World Championship team. Shamier Little was the odd woman because her time of 53.91 is a time that only 3 women in the world beat this year, but all three women were the three women from the US in front of her.
