The winner in Rio will attempt to defend her title
The Jamaican cruised through in first place in her semi-final, equalling her lifetime best with 21.66 seconds, but the surprise came in Gabby Thomas being edged out to second place by Namibia’s Christine Mboma. A time of 21.97 was a PB and a World U20 record for Mboma, as well as sealing her place in the final.
Great Britain’s Beth Dobbin faced a tough task to make the final and ended her semi in fifth.
Just earlier, Thompson-Herah’s compatriot Shelly-Ann Fraser-Pryce won the first semi-final, with Beatrice Masilingi of Namibia in second.
And it was Marie-Josee Ta Lou of Ivory Coast, and Bahamas’ Shaunae Miller-Uibo who took the top two places in the third semi-final.
Swiss athlete Mujinga Kambundji came third, but her time of 22.26 was good enough to seal a spot in the final, along with Team USA’s Thomas, who clocked 22.01.
The big talking point will remain Thompson-Herah’s performance, though, with her semi-final time just 0.32 seconds off the world record – and she visibly eased off in the final few metres of her run.
A 100m and 200m gold double looks distinctly on the cards for the 29-year-old – just as she achieved in Rio five years ago.
