Defending champion Shelly-Ann Fraser-Pryce and Shericka Jackson are through to the finals of the 100m. So, too, was Julien Alfred of St Lucia who continued her unbeaten run this season by taking her semi-final heat to advance to her first global final.

American medal hopeful Sha’Carri Richardson and the dangerous Marie Jose Ta-Lou are also through into what is expected to be a cracking final.

Fraser-Pryce who is going for her sixth world 100m title but whose preparation this season has been interrupted by a long-running knee injury, eased out of the blocks but rushed past the field to win her heat in 10.89.

The USA’s Tamari Davis secured her spot in the final by finishing second in 10.98.

Jackson, meanwhile, was more impressive getting a good start and cruised to victory in 10.79, just ahead of an impressive Ta Lou, who was just as easy finishing second on 10.79. Richardson, who was left in the blocks managed to take third in 10.84, a time that eventually got her into the final.

Alfred, who is unbeaten in the 100m this season, survived a scare in her heat after receiving a yellow card for a faulty start. However, having dodged a repeat of her fate at the 2022 World Championships, she started cautiously but stormed past the field to win in 10.92.

Britney Brown of the USA booked her finals berth after running 10.97 for a second-place finish.

Great Britain’s Dina Asher-Smith made it into the final having finished third in 11.01.
