No dream end for Makwala as Guliyev powers to 200m win
Turkey's Ramil Guliyev shocked Wayde van Niekerk to clinch the 200m title at the World Championships. South Africa's Van Niekerk claimed silver to miss the chance to become the first man since Michael Johnson in 1995 to win the 400m and 200m double.
Guliyev won in 20.09 seconds, with Jereem Richards third, Great Britain's Natheneel Mitchell-Blake fourth and Botswana's Isaac Makwala sixth.
Van Niekerk ran 20.11 seconds, with Richards crossing just one thousandth of a second behind.
Botswana's Makwala qualified on Wednesday after running a solo time trial and the semi-final, having been controversially denied entry to the stadium on Tuesday as world governing body the IAAF tried to combat an outbreak of the norovirus.
Makwala and Botswana had been critical of his treatment and the 30-year-old said he was running heartbroken after not being allowed to race in the 400m.
But he was never in contention as Guliyev won Turkey's first gold of the championships.
Earlier, two-time Olympic champion and defending champion Christian Taylor won the triple jump, ahead of United States team-mate Will Claye, with a leap of 17.68m as Portugal's Nelson Evora took bronze.
On a successful night for the US, Kori Carter claimed the 400m hurdles title, with team-mate Dalilah Muhammad taking silver and Jamaica's Ristananna Tracey third.
Carter said: "I knew I had to run strong. I'm on top of the world. I have made so many sacrifices and I'm so blessed."
Laura Muir and Eilish McColgan qualified for Sunday's 5,000m final last night.
Sir Mo Farah's 10,000m gold last Friday was hosts Great Britain's only medal in the first six days of competition and his quest for a golden double continues in tomorrow's 5,000m final.
The heats of the corresponding women's event opened proceedings. British record holder Muir, who finished fourth in the 1,500m on Monday, was in the first heat and had to be in the top five to be sure to advance.
Muir was overtaken by two athletes in the final 100m as she clocked 14 minutes 59.34 seconds to place seventh in her heat, which was won by Hellen Obiri of Kenya in 14:56.70.
Muir had to wait until the second heat concluded to learn if she would progress. She did so and was joined by McColgan.
Muir said: "I felt good out there apart from that last lap. I know I'm better than I ran today and hopefully I can show it in the final."
Meanwhile, 22-year-old Irishwoman Siofra Cleirigh Buttner finishing sixth in her 800m heat in a time of two minutes and 6.54 seconds, which wasn't enough to ensure her progress to the semi-finals.
