Great Britain’s Dina Asher-Smith failed to make the 100m final after clocking a below-par 11.05 seconds in the semi-final.
The 25-year-old, who ran 10.83 to take silver at Doha 2019, was third behind Jamaica’s Elaine Thompson-Herah and Swiss Ajla del Ponte.
It left her needing a fastest loser spot, but GB team-mate Daryll Neita took the final lane with a time of 11.00.
Asher-Smith missed her final warm-up event in July with a tight hamstring.
