Jamaica's Orlando Bennett, the second fastest in the heats, wins the first semi-final in 13.27 seconds.

After a tense wait, Spain's Enrique Llopis' second place finish is confirmed.

The surprise, however, is that USA's Dylan Beard has been pipped into third place by Japan's Shusei Nomoto (13:30), who lunged for the line.

Remember, the top two in each semi-final, plus the two fastest non-automatic qualifiers, will be in the final at 14:20 this afternoon.

There is nothing wrong with Grant Holloway, no injuries, but what his problem is at the moment is that he's lost his timing.

At this level, you can't afford 1/100th of a second to be given to competition over every hurdle. Holloway is in a spot of trouble.

Coming up at 12:40, it's the men's 110m hurdles semi-finals.

Defending champion Grant Holloway (USA) had a tricky time in qualifying, only coming fourth in his heat after fading in the second half of the race.

Instead, it was Jamaica's Tyler Mason, who ran the fastest qualifying time of 13.17 seconds, his compatriot Orlando Bennett, and Spain's Enrique Llopis who impressed on Monday.

Other names to watch are France's Just Kwaou-Mathey, who in August became only the fifth European sprint hurdler to break the 13-second barrier, and USA duo Cordell Tinch and Ja'Kobe Tharp.

Tinch ran a world-leading 12.87 in May and recently ran 12.92 to win the Diamond League final. 19-year-old Tharp is the reigning US champion and was just two thousandths of a second off top spot in his heat.

Day four of the World Athletics Championships will see four finals take place, with the men's high jump final getting under way now.

Olympic champion and world number one Hamish Kerr of New Zealand is no doubt one of the favourites for first position after clearing 2.25 metres on his second attempt in qualifying.

Sanghyeok Woo of South Korea will also be one to watch - he beat Kerr to gold at the World Indoors earlier this year after a successful 2.31m jump, and is unbeaten in 2025. Kerr has a season's best of 2.33m so can he step it up for the final?

Yual Reath of Australia achieved his season's best in qualifying, clearing 2.25m, so it is all to play for.

Ukraine's Oleh Doroshchuk and USA's JuVaughn Harrison also feature.

2019 world champion Donovan Brazier continues his remarkable return from a three-year injury absence to win the final heat in 1:44:66, followed by Algeria's Slimane Moula in second and Croatia's Marino Bloudek in third.

Kenya's Nicholas Kiplangat Kebenei is fourth in 1:44:91, which is quick enough to see him through as the fastest non-automatic qualifier.

As a result, Australia's Peter Bol, one of the big names, drops out in the heats.

Very promising starts by Max Burgin and Ben Pattison in the men's 800m competition.

The pair, long time rivals on the track, know each other very well - but we've not seen them go head-to-head as often as many fans would have hoped because of their respective injury issues over recent years.

Behind only Sebastian Coe on the British all-time list, they both looked in great shape in those heats.

Let's hope we'll see them both racing for the medals here because, make no mistake, that is what they intend to do.

Men's 800m semi-finalist Max Burgin speaking to BBC Sport: "I'm happy with the way it went. Ran it nice and safely and finished in the automatic spot.

"It's always stressful these heats. You never know how fast they're going to run. I'm happy with that. I went in knowing what I needed to do and I was happy moving up around 600m.

"I am hoping to challenge for a medal. I've shown throughout the season I'm capable of being in that conversation. In my mind there's no reason why I shouldn't be getting through that semi."

That was a quick heat! GB's Max Burgin takes first and secures his spot in the semi-finals with a time of 1:44.73.

Botswana's Tshepiso Masalela and Jamaica's Navasky Anderson take the other two automatic qualifying spots, but France's Yanis Meziane and Belgium's Eliott Crestan ran times that should see them through as fastest non-automatic qualifiers.

It was really nice to see Ben Pattison really confident and back to full fitness.

He controlled the race from the front, and he's so strong on the home straight.

No drama from Olympic champion Emmanuel Wanyonyi as he eases into the semi-finals.

After getting a little boxed in at the start of the second lap, he cruises back up to the front and even has time to look around before winning heat five in 1:45.05.

Italy's Francesco Pernici and Ireland's Mark English take second and third in a fast heat.

Cian McPhillips' run will wake up the other men. That is a composed run with plenty left in the tank.

Ireland's Cian McPhillips runs a superb race to win heat four in 1:44:91, pipping 2024 world indoor champion Bryce Hoppel and Jamaica's Tyrice Taylor in a sprint finish.

Australia's Peter Bol finishes fourth, but should be quick enough to progress as one of the three fastest non-automatic qualifiers.

Great Britain's Ben Pattison speaking to BBC Sport after qualifying for the men's 800m semi-finals: "It was kind of getting into a good position, my coach said at 300m to stay alert, then make moves.

"I gradually slowed it down. Each time there was a move I made sure I didn't get boxed in.

"I felt really good, warming up was the best I've felt in a long time. Confidence is high after that race.

"I feel like a lot of people who had the year I had would just be happy to be here, but that's not my mindset, I have a job to do and a medal to defend. The semi-finals are going to be tough."

In heat three, GB's Ben Pattison claimed second place to secure his spot in the men's 800m semi-finals.

Poland's Maciej Wyderka took first, with France's Gabriel Tual claiming the final automatic qualifying spot.

There was a shock exit for USA's 16-year-old Cooper Lutkenhaus who finished down in seventh with a time of 1:47.68. He's ran a personal best of 1:42.27 this season, so no doubt we will see plenty more of him in the future.

A reminder that the top three in each heat qualify automatically for the semi-finals, where they will be joined by the three fastest non-automatic qualifiers.

More than the Score

After Armand Duplantis broke the men's pole vault world record for the 14th time yesterday, we've got a bonus episode of the More than the Score podcast.

Ed and Ade explore the making of Mondo, reflect on his exploits in Tokyo, and revisit an interview they conducted with Mondo and his dad on his formative years.

Listen here.

That was a little nervy for defending champion Marco Arop. The Canadian is nearly run out of the final automatic qualifying spot but just hangs on to third.

Spain's Mohamed Attaoui wins heat two in 1:45.23, with Kenya's Kelvin Loti in second. Spain have won the first two heats.

Tiarnan Crorken, on debut, misses out. It looks like he placed around fifth.

It doesn't quite feel right that the pole vault equipment was already packed away before the start of night four here at Japan's National Stadium, less than 24 hours after Mondo Duplantis gave us that record-breaking moment.

This is the emptiest I have seen the stadium during a night session so far - I'd say it's roughly three-quarters full - despite another exciting selection of heats, semi-finals and medal races to come.

It's been a glorious day in Tokyo, with blue skies and strong sunshine pushing the temperatures above 30C, and it perhaps doesn't feel quite as humid as it has been.

Maybe I'm just getting used to it. Don't get me wrong, it's still about 28C at approaching 8pm local time here, but these feel like pretty perfect conditions for quick times this evening...

Spain's David Barroso is the surprise winner of heat one in 1:44:94, followed by Olympic bronze medallist Djamel Sedjati of Algeria in second.

Kethobogile Haingura of Botswana takes the final automatic qualification spot.

Handal Roban of Saint Vincent and the Grenadines led for most of the race but fell down to fifth on the final straight.

A reminder that the top three in each heat qualify automatically for the semi-finals, where they will be joined by the three fastest non-automatic qualifiers.

Events come thick and fast at the World Championships, with the women's triple jump qualifiers getting under way.

While there are no Brits involved, there are some fascinating stories to keep tabs on.

Tokyo 2020 gold medallist and seven-time indoors and outdoors world champion Yulimar Rojas will effectively make her comeback 17 months after injuring her Achilles.

The Venezuelan withdrew from an attempted return in March after registering four no jumps, and pulled out of a meeting in August because of muscle overload.

Olympic champion Thea LaFond was a teacher until 2022, but last summer won the Dominican Republic's first Olympic medal in any sport.

Leyanis Perez of Cuba could well be the favourite having registered five of the six top jumps this year, including two beyond 14.90 metres. In March she won the world indoor title, though only managed fifth place in last summer's Olympics.

Compatriot Liadagmis Povea won world indoor silver in March, her first senior career medal, while Jamaica's Shanieka Ricketts and Jasmine Moore of the United States will look to build on the silver and bronze medals they won at Paris 2024.
