Women's 100m hurdles semi-final
Disappointment for American Masai Russell. She makes a great start, but hits the second hurdle, clatters into the third, that throws out her rhythm and by hurdle seven it is all over for her.
Nigeria's Tobi Amusan, ranked first in the world, gets the win in 12.56, followed by Nadine Visser of the Netherlands in 12.60. They will be the only two from the second heat in the final.

Molly Caudery is going al -in here.
Having produced a personal best clearance over 4.75m, she takes the bold decision to pass on the next height and focus on 4.85m - which would bring a real chance of a world medal.
All eyes are on this final right now. Three medals on offer, five athletes in contention.
The board is full of lifetime and season bests, as well as a national record for Azerbaijan's Hanna Skydan. It's heating up very nicely!

Britain's Molly Caudery has passed at 4.8m after one failure but if she clears the next height, 4.85m, it may well get her a medal.
Angelica Moser of Switzerland fell at the 4.8m mark, so only five remain.

Kendra Harrison is just so, so fast. I know it's obvious to say but between the barriers, she shifts.

Ireland's Sarah Lavin sets a new Irish record of 12.62 seconds, but it is only good enough for fifth and she misses out on the final, as does Britain's Cindy Sember, who came sixth in 12.97 after a sluggish start.
American Kendra Harrison storms to the win in 12.32 with Devynne Charlton of the Bahamas also securing automatic qualification with 12.49.

Women's pole vault final
There are only six competitors left in the women's pole vault and what a performance from Britain's Molly Caudery, who is ranked 19th in the world.
Can she grab a medal? It would be the fourth Great Britain have won in the 2023 World Athletics Championships so far after one gold, one silver and one bronze.

YES Molly Caudery!
What a time to produce a personal best.
The 23-year-old clears 4.75m with her third and final attempt to keep her medal hopes alive in the women's pole vault final, drawing huge cheers from the crowd.
She's delighted with that, revealing a beaming grin as she sits up on the mat and celebrates that lifetime best to move up to fourth on the board.

Only the top two in each of the three semi-finals are guaranteed a place in the final and they will be joined by the two fastest losers.
Semi-final 1: Former world record holder Keni Harrison (lane 7) dropped the joint-fourth fastest time in history in her heat yesterday, explaining she plans to run every race flat out because it “gets my body in that rhythm” in anticipation of a super-fast final.
Olympic medallist Megan Tapper (lane 5) has strong competition for the other automatic spot, including from Ireland’s Sarah Lavin (lane 4). Cindy Sember is in lane 8 for Britain.
Semi-final 2 (19:53 BST): Reigning champion Tobi Amusan (lane 7) won her heat yesterday five days after being cleared of a doping violation for three whereabouts failures within 12 months; the reasons why a tribunal found her innocent are expected to be made public today.
Semi-final 3 (20:01 BST): Two of the event favourites, Jasmine Camacho-Quinn (lane 5) and Nia Ali (lane 6) go head-to-head. Olympic champion Camacho-Quinn has beaten the American in all five meetings this year and 18 of 19 overall.

I think she got a taste of what it could be like at the top with that Commonwealth silver last year and said 'I like this, I want to be this more often'. I've seen her training in Loughborough and she has worked so, so hard to get here.
Women's pole vault final
Britain's Molly Caudery is one of only eight competitors left in the pole vault and is aiming to clear 4.75m, which would become a personal best.
But two failures so far. One last chance to stay in the competition.

Sifan Hassan of the Netherlands won her women's 5,000m heat, out-sprinting rival Faith Kipyegon, and has been talking to the BBC.
Hassan said: "I feel good. I think after the marathon, I have adapted to the pain. This morning I woke up like 'let me go a little bit harder'. I enjoy the pain and the longer stuff."
Asked whether it was important to finish first ahead of Kipyegon, she said: "I really didn't care because I was leading the whole race. If it's important to her, it's important to me also."
