Identical podium
And at Oregon 2022, the champion nonpareil, raised the bar yet again. Behind her, Netherlands' Olympic bronze medallist Femke Bol clinched silver in 52.27, while USA's former world record-holder Dalilah clocked 53.13 for bronze.
It is a performance that will be looked at by all other 400M hurdlers, and indeed fans of the sport, as something out of this world and that is exactly what it is - to everyone but McLaughlin! Kudos champ!
Surging ahead
"Honestly I just wanted to go for it," McLaughlin said afterwards. "The last 100 really hurt, but I'm grateful to have this crowd. Go Team USA!"
Femke and Dalilah would have had realistic hopes of challenging McLaughlin for gold before the race. But McLaughlin was in a league of her own almost from the gun, surging clear of Dalilah with a blistering opening 200M and coming off the final bend several meters clear of her rivals.
Astonishing time
Any fears that McLaughlin had gone out too hard over the opening 300 was wiped out down the home stretch as she kicked for home with a vengeance, powering through the line to complete one of the greatest performances in track and field history.
Her astonishing winning time was faster than the seventh and eighth placed times in the women's flat 400M final raced earlier in the evening.
Final stretch
McLaughlin sat crouched on the track after her win, seemingly in disbelief at the scale of her own achievement. Let us just leave that time there, sitting on its own, because that is what it will now do on the all-time lists - by some distance the most spectacular performance to date at the World Athletics Championships Oregon22.
After eight days of high-octane action, this is the first world record set at Eugene 2022, which concludes on July 24.
