The American Sydney McLaughlin was the big favorite before the women's final in the 400 meter hurdles.

And she delivered.

The 22-year-old is totally superior throughout the race, took gold by a good margin and beat his own world record by 73 (!) hundredths.

The new time is 50.68.

- It could be the best performance in the entire WC.

Unbelievable, says expert Christian Olsson.

Alhaji Jeng is equally impressed.

- She continues to dominate.

I'm out of words.

What an achievement.
