Jamaica's Shericka Jackson displayed a commanding performance to retain her world 200m title in 21.41 seconds on Friday, recording the second-fastest time ever raced.

Only Florence Griffith-Joyner’s world record of 21.34 from 1988 is faster (with 1.2 meters/second more tailwind than Jackson had). Jackson won last year’s title in 21.45.

Americans Gabby Thomas (21.81) and Sha'Carri Richardson (21.92) won silver and bronze, respectively.

Richardson, the gold champion in the 100m, became the first American woman to win both the 100m and 200m titles at the World Championships since Carmelita Jeter in 2011. In both finals, Richardson ran the fastest times of her life.

Julien Alfred of St Lucia finished fourth in 22.05, while Daryll Neita of the United Kingdom finished fifth in 22.16.

After Jamaica and the United States qualified for Saturday's 4x100m relay final earlier on Friday, all of the medalists are anticipated to share the track one more time.
