Bolt (19.55) wins 200m gold from Gatlin in silver (19.74)
GB's Zharnel Hughes fifth
USA's Allyson Felix wins 400m for ninth world title
Christine Ohuruogu eighth in 400m
GB's Sophie Hitchon fourth in hammer final
Asher-Smith wins 200m semi in 22.12
GB's Oskan-Clarke wins 800m semi-final
For those who need reminding, defending champ Christine Ohuruogu won the title in Moscow by four thousandths of a second. Will this one be a heart-stopping race to the line? They're in the blocks... seconds to go...

"Christine has a great inner self-belief and I just admire her so much with the way she is able to focus, visualise and get herself into that race-mode. She has been here before. Who would bet against her?"
How can we top that grand finale? By turning our attention to the lady who knows all about dramatic endings. Christine Ohuruogu is not the favourite for the women's 400m final - America's Allyson Felix is - but the Briton never starts as the woman to beat.

Pedro Pablo Pichardo has watched Christian Taylor produce a world leading jump. What can he do? The Cuban asks for silence before he sprints down the runaway.
It's a big one... but his 17.73m is not good enough. A magnificent finale.

Triple jump world record holder on BBC Radio 5 live
Quote MessageThat was a remarkable jump. Nothing we have seen in this competition had indicated they would jump that far but that was phenomenal from Taylor.
Christian Taylor, the leader, has one jump remaining, he urges the crowd to carry him to glory... Off he goes...
And the Olympic champion covers 18.21m - the second best in history! Jonathan Edwards is laughing.

Quote Message"This is Shelayna's first major championships, her first sub two-minute race. Now we have an athlete strong enough and good enough. "She must be absolutely delighted. This is her first season of international competition, her first major championships and now she is getting ready for her first World Championships final."
GB's Oskan-Clarke through to 800m final

Quote MessageThe last British athlete out of the three you'd expect to be in the final was Oskan-Clarke, but if it becomes a technical, tactical race she could snatch a medal.
Image source, ReutersOne more 800m semi-final to go and rice paper separates the top three finishers in a pacy race. Lynsey Sharp was in a good position after 400m, but the Briton ends up eighth in 1:59.33.
Three personal bests in that race, with Melissa Bishop breaking the Canadian record in 1:57.52. Second was Marina Arzamasova of Belarus.
Dutchwoman Sifan Hassan, the European champion, was fifth and misses out on the final.
Women's 800m semi-finals
Quote MessageThese semi-finals are really, really tough. I knew I was up against it but when you are standing on the startline you hope. I was looking for 1.59, that would've been a consolation, but I didn't do myself justice. I felt lacklustre and lethargic but had no reason to feel like that. I've had a number of years injured and being ill and it feels quite alien competing against the people you've been watching for so long. I give myself a two or three out of 10. It's a season best, but not what I was looking for."

Quote MessageI was fighting all the way trying to get myself into the right position. I felt strong and said to myself 'come on, push, push, push'. I knew I could run under two minutes. I'm so happy and my coach has been saying I could do it for ages. To be in a final sounds amazing. I just want to take each race as it comes and I knew the fitness was there.

Sophie Hitchon twice broke the British record, but she narrowly misses out on bronze. She still manages to smile, though. Her 73.86m best was 16cm off France's Alexandra Tavernier in third.

Quote MessageOskan-Clarke has been promising so much, she's a lovely character, has loads of guts and ability but it's not all come together until now. That will give her so much confidence in the final.
Screams of delight from Britain's Shelayna Oskan-Clarke after she sneaks through on the inside to win the 800m! She's through to the final, a gutsy 1:58.86 personal best in her first major championship and see goes nine on the British all-time list.
Hello Christian Taylor, welcome to the top of the triple jump leaderboard. The Olympic champion covers 17.68 on his fourth attempt, which pushes Pablo Triple P into second.
Where's this world record everyone's been talking about? They're way off Jonathan Edwards' mark at the moment.
