LONDON (AP) The Latest from the world championships (all times local):
Phyllis Francis of the United States upset the favorites to win the 400 meters at the world championships.
Olympic champion Shaunae Miller-Uibo looked poised to win gold until she slowed in the final meters.
Salwa Eid Naser swept past Allyson Felix in the final meter to lunge at the line for silver, ahead of the American veteran.
Francis finished in 49.92 seconds, .14 seconds ahead of Naser. Felix took third in 50.08 and Miller-Uibo was fourth.
Karsten Warholm of Norway won the world title in the 400-meter hurdles, holding off Yasmani Copello of Turkey and Kerron Clement of the United States.
The 21-year-old Warholm earned his first major title, and then looked up in amazement as the result showed on the giant screen.
The Norwegian won in 48.35 seconds, .14 seconds ahead of Copello. Clement, a two-time former champion, finished in 48.52.
Gong Lijiao of China won the shot put title at the world championships.
Anita Marton of Hungary took silver and Olympic champion Michelle Carter of the United States got bronze.
Gong took the lead on her penultimate throw and won with a toss of 19.94 meters. Marton then crept into second position on her last throw, tossing it 19.49 and pushing Carter into third. The American had a mark of 19.14 meters.
Wayde van Niekerk is still on track for a 200-400 double at the world championships.
The South African runner qualified for the final of the 200 meters on time after finishing third in his heat.
With only two automatically through from the three semifinals, Van Niekerk's time of 20.28 was good enough for the last spot in Thursday's final.
Van Niekerk already won gold in the 400.
Isaac Makwala qualified for the 200-meter final at the world championships after getting a late go-ahead to compete.
After missing the heats with a stomach bug two days ago, Makwala first made the semifinals in a specially approved solo-run. He then ran a blistering race from the inside lane to reach the final as the second finisher from his heat behind Isiah Young from the United States.
The inside lane is tough in the best of conditions, but it was even more difficult because most of the water from the relentless rain had settled there.
Makwala pumped his right arm as he crossed 20.14 seconds, .02 seconds behind Young.
Olympic silver medalist Paul Chelimo took a tumble with four laps to go in a tangle with Cyrus Rutto of Kenya, but both recovered and qualified for Saturday's final in the 5,000 meters at the world championships.
With four laps to go, Chelimo hit the rain-drenched track and somehow dragged Rutto down with him. Both got up quickly and caught the lead pack.
Rutto finished third and was among the five automatic qualifiers. Chelimo advanced by being among the top five non-automatic qualifiers from the two heats.
In cold and wet weather that had some athletes competing in leggings and gloves at the world championships, Darya Klishina of Russia had the top mark to qualify for Friday's long jump final.
The conditions in the chilly Olympic Stadium were such that no one made the automatic qualifying standard of 6.70 meters. Klishina, competing as a neutral athlete because of Russia's doping suspension, jumped 6.66 meters, edging Tianna Bartoletta of the United States by 2 centimeters.
European champion Ivana Spanovic of Serbia was also through, as was this year's world leader, Brittney Reese of the United States.
Mo Farah was back at the Olympic Stadium and got the sellout crowd at the Olympic Stadium roaring for his heat in the 5,000 meters.
In relentless rain, the Briton ran a controlled race and coasted home in second place to automatically qualify for the final behind Yomif Kejelcha of Ethiopia.
Farah won the 10,000 meters on Friday for his sixth word championship gold and he is going for No. 7 on Saturday. It would also clinch his fifth straight long-distance double at a global championships, starting with his double at the Olympic Stadium during the 2012 London Games.
Isaac Makwala has qualified for the 200-meter semifinals.
The runner from Botswana, who came down with a stomach bug and was forced to miss Wednesday's 400 final, was belatedly allowed to run his qualifying heat, two days after all his competitors did so.
Needing to run 20.53 seconds or faster to advance, Makwala braved the rain and cold at the Olympic Stadium and finished in 20.20.
Makwala immediately got down after his race and did five pushups.
The semifinals are later Thursday.
Wayde van Niekerk, Makwala's rival for gold, watched in a rest zone and applauded his performance.
Isaac Makwala is getting a belated chance to compete in the 200 meters with a solo run and one opponent - England's world famous rain.
Makwala was first barred from competing in the 200 heats at the world championships because he was forced into quarantine with a stomach bug. But the IAAF has given him another shot at a medal with a special exemption to run early in Wednesday's program. Makwala had been going for a 200-400 double but the virus forced him out of the 400 final.
Rain is set to come pouring down through the evening.
The women's 400-meter final is the highlight medal event of the night. There are also finals in the women's shot put and the men's 400 hurdles.
