Dina Asher-Smith claimed a historic hat-trick at the World Championships as Great Britain celebrated double silver in the women’s and men’s 4×100 metres relay in Doha.
The 23-year-old becomes the first British athlete to win three medals at the same World Championships.
Having already claimed 200m gold and 100m silver at the Khalifa International Stadium, on Saturday she linked up with Asha Philip, Ashleigh Nelson and Daryll Neita as the quartet finished second behind Jamaica in 41.85 seconds. The United States were third.
The men’s 4x100m squad of Adam Gemili, Zharnel Hughes, Richard Kilty and Nethaneel Mitchell-Blake then added another silver, unable to defend the title won in London two years ago.
They clocked 37.36 seconds, a European record, behind favourites the US, with Japan winning bronze.
That was despite Hughes suffering a hamstring injury during his leg.
“When I was running, when I handed the baton, I pulled my hamstring,” Hughes, who had strapping around his leg, told the BBC.
“I had to give it to Richard whatever because tonight was about getting a medal. We are going home with something around our necks.”
Kilty added: “It took an American record and the second fastest time ever to beat us.
“What a warrior Zharnel is. He ran through the zone with a poor hamstring. I heard something happen and I had to slow down my run.
“We came out here like brothers. We are buzzing. We ran an European record. We can get gold in Tokyo (at the 2020 Olympics).”
“It puts the spark in us next year to push on,” Gemili said.
On the women’s team’s silver, Asher-Smith said: “I think we all handled the pressure between us, which is testimony to how much experience we have got as a squad. We almost ran a personal best without practising any of the changes in the warm-up area. It’s been a good champs, but obviously it’s a team event.”
Earlier, Shara Proctor and Abigail Irozuru qualified for Sunday’s long jump final, but Jazmin Sawyers missed out.
Proctor said: “The runway feels amazing. Regardless of the crowd, lack of numbers, the atmosphere is electric.
“I enjoyed being out there. I really had to contain myself as I knew I had a job out there.
“It’s the first part of the job done, I had one job and that was to come here today and make the final.”
Cindy Ofili came through the 100m hurdles heats, finishing third in 12.97s.
She said: “Things have started clicking for me towards the end of this season and I am so ready.
“I haven’t competed in three years at a championship so this is a dust-buster and the jitters are out now.”
In the women’s 4x400m relay heats Zoey Clark, Jodie Williams, Jessica Turner and Laviai Nielsen reached Sunday’s final in 3:24.99.
The men’s team of Cameron Chambers, Rabah Yousif, Martyn Rooney and Lee Thompson scraped into the final after Botswana were disqualified.
