Dina Asher-Smith returned as Great Britain set a new national record to win their heat and reach the women’s 4x100m relay final on Friday.
The 200m world champion ran the third leg as the British quartet finished ahead of the USA and Jamaica in 41.55 seconds.
Asher-Smith, who tore her hamstring in July, pulled out of the Olympic 200m after failing to make the 100m final.
Asha Philip, Imani-Lara Lansiquot and Daryll Neita completed the GB team.
“There was never any doubt in my mind that I’d be lining up here today because the relay’s really important, we got a bronze medal in Rio,” Asher-Smith told BBC Sport.
“These ladies are in great shape, they’re incredibly talented, so I knew I had to rest up and get ready for the team event. I’ve been training hard to get ready.”
Individual women’s 100m gold medallist Elaine Thompson-Herah and silver medallist Shelly-Ann Fraser-Pryce did not run for Jamaica but both are likely to return for Friday’s final.
The British men’s 4x100m team of Chijindu Ujah, Zharnel Hughes, Richard Kilty and Nethaneel Mitchell-Blake also advanced into Friday’s final after coming second in their heat with a time of 38.02.
Parchment causes shock as Pozzi finishes seventh
Britain’s Andrew Pozzi came seventh in the men’s 110m hurdles final as Jamaica’s Hansle Parchment finished strongly to take gold ahead of American favourite Grant Holloway.
World champion Holloway, who had not lost a hurdles race since August 2020, dropped momentum in the later stages of the race allowing Parchment to surge past him with a season-best time of 13.04.
Jamaica’s Ronald Levy claimed bronze in 13.10, one hundredth of a second behind Holloway.
Meanwhile, Britain’s Morgan Lake progressed into the women’s high jump final after clearing the automatic qualifying height of 1.95m.
However, her team-mate Emily Borthwick missed out despite equalling her personal best of 1.93m.
