Aug. 3 (UPI) -- American runners Sydney McLaughlin and Dalilah Muhammad delivered a one-two punch in Tokyo on Wednesday in the women's 400-meter hurdles, with both of them shattering the world record in the race.
McLaughlin, 20, ran a blistering 51.46 seconds, obliterating the world record of 51.90 that she set last month when she became the first woman to run the event in under 52 seconds.
The 31-year-old Muhammad, the reigning gold medalist in the event, also broke the previous world record with a time of 51.58 and took the silver.
The Netherlands' Femke Bol, 21, won bronze and broke a continental record with a time of 52.03 seconds.
The record-setting race came a day after Norway's Karsten Warholm, 25, became the first person to run the 400-meter hurdles in under 46 seconds (45.94) -- a race that could be one of the greatest heats in history, as seven of the eight runners broke world continental or national records.
A third American in Wednesday's race, Anna Cockrell, 23, was disqualified. Janieve Russell of Jamaica finished more than a second after Bol crossed the line.
The women got off the blocks fast with McLaughlin, Muhammad and Bol clearly leading the pack with the reigning Olympic gold medalist leading after the penultimate barrier.
McLaughlin continued to push and passed Muhammad on the jump over the last barrier and the two ran nearly side-by-side with Bol two strides behind.
