Women's heptathlon - high jump
Steve Backley
Two-time world javelin silver medallist on BBC TV
Second event of the heptathlon underway, the high jump. Katarina Johnson-Thompson, first attempt at 1.77m - that's good.
High jump is an event where she is world class and expects to get lots of points, she's off to the perfect start there

Meanwhile, so far so good for Katarina Johnson-Thompson, clearing 1.77 in the high jump.
Netherlands 2-0 Great Britain
A dominant second quarter from the Netherlands and they lead 2-0 at half time.
Work to do for defending champions Great Britain if they want a place in Friday's final.
Men's 110m hurdles semi-final
Devon Allen seems a very confident chap. He finishes quickest in the second 110m hurdles semi-final with 13.18 and promptly does some sort of Peter Crouch-esque robot dance before grabbing and staring into the camera.
Women's 400m hurdles final
Image source, Getty ImagesNow then, could we see another 400m hurdles world record?
American duo Sydney McLaughlin and Dalilah Muhammad renew their rivalry in the final and this has the potential to be rapido.
McLaughlin, who turns 22 on Saturday, set a new world mark of 51.90 seconds in the US trials, where reigning Olympic and world champion Muhammad finished second.
Muhammad, 31, was the previous record holder with the 52.16 she ran in the 2019 world championship final in Doha, where she pipped McLaughlin to gold by just seven-hundredths of a second.
Add Netherlands' Femke Bol into the mix and there could well be fireworks.
Men's 110m hurdles semi-fnal
Steve Cram
Athletics commentator on BBC TV
Very close! Pozzi looked good in the middle section of the race but wilted a little towards the end.
That was a good race, a close race.
Men's 110m hurdles semi-final
Image source, .Oof! That was a close race, edged by Jamaica's Ronald Levy as he finishes with a time of 13.23.
Pascal Martinot-Lagarde is second, Asier Martínez third and Great Britain's Andrew Pozzi fourth quickest. In with a shout of getting into the final.
Netherlands 2-0 Great Britain
Oh no! The Netherlands have scored twice in as many minutes to take a 2-0 lead over Great Britain in the hockey semi-finals.
Felice Albers and Marloes Keetels were both unmarked as a period of Dutch pressure paid off.

GB's Sky Brown on BBC One: "That was insane. It's crazy to be here, skating with all the girls has been really fun. Everyone has been ripping - it's awesome, awesome to be here.
"I'm really stoked with my score. I have some other tricks, but I'm just going to enjoy my time being in the Olympics."

Reporter on BBC TV
You don't have to know anything about skateboarding to see Sky was a stand-out, just brilliant.
It was high, the style was there - she's 13-years-old and she's doing tricks that were invented 20 years before she was born and she's doing them as they were designed to be done.
Every trick is flawless, everything is brilliant to watch. I love it.
Netherlands 0-0 Great Britain
At the end of the first quarter, it remains goalless between the Netherlands and Great Britain in their semi-final.
The Dutch had two penalty corners right at the end but GB goalkeeoer Maddie Hinch pulled off some decent saves.
It's been fairly even though, which is encouraging for GB.

Sky Brown making it look so easy. Give us some more, Sky! That was pretty much a warm-up run, just to get ready for the final coming up.
She got a 40.03 even though she stopped with 16 seconds to spare, that's how good she is.
Women's park - Heat 3
A 40.03 on the last run for Sky Brown but she had already secured qualification into the final so understandably took things a bit easier. No point risking an injury for the final.
That final is coming up at 04:30 BST - no going to sleep now!

Dee: Thought we’d watch a bit of the ladies' skateboarding to see what all the fuss is about… now not going to bed until it’s done!
Jos: Sky Brown having a walk in the skatepark, with a smile as wide as Tokyo Bay!
Christelle: Wait... This girl is a serious contender in skateboarding freestyle. Am I staying up all night again?

Perfectly timed and another great run for Great Britain's Sky Brown. Amazing execution.
It's not just getting the tricks in, it's getting them in on time. 45 seconds goes by in the blink of an eye when you're on the park.

She's already become the youngest British summer Olympian but will she also make even more history by becoming the youngest Olympic champion before people in the UK have even got up for breakfast?

Effortless again from Sky Brown as she goes even better in her second run, scoring 57.40.
At the moment she is looking in a league of her own.
