We've just seen a great run from Jamaica's Oblique Seville in the first semi-final, can compatriot Ackeem Blake follow in his footsteps here?

Defending champion Marcell Jacobs is looking pretty calm and composed.

Ready for this?

Noah Lyles got out well but Oblique Seville, the technique was impeccable.

He was so clean in terms of his sprinting. Lyles was looking over and saw that he wasn't winning the race. That will play on his confidence.

Oblique will certainly go into that final with a lot of confidence.

Noah Lyles is not the fastest man in the world and there is definitely a little less dazzle with him here. That is the most animated we have seen him, he certainly wasn't like that in the heat. No athlete likes getting beaten, particularly when you get to the Olympic semi-finals.

It is all about pushing the chest out, being brash and making a statement. I didn't see the statement from Noah, but it did come from Oblique Seville.

Marcell Jacobs claimed a surprise gold in the men's 100m in Tokyo.

The Italian, who only switched away from long jump in 2018, streaked clear to win in 9.80 seconds, leaving the then world champion Christian Coleman and Trayvon Bromell, the world's fastest in 2021, far behind.

Few would have picked Jacobs, who was born in Texas to an American father but moved to his mother's Italian homeland before his first birthday, as Jamaican great Usain Bolt's successor for Olympic gold.

Jacobs missed out on the final of the 2023 World Championships, but he defended his European title in June.

He's in the next semi-final...can he retain his Olympic title?

Oblique Seville looks so relaxed. Controlled.

Usain Bolt has called this man to take this title and when someone like Usain Bolt says that, sometimes you have just got to listen.

We know Noah Lyles can win these big events and raise his game and lift his performance but right now, Seville has got the nod over him.

Wow.

Dropping a personal best in the Olympic semi-finals? That is some statement from Oblique Seville to edge Noah Lyles to victory in a high-quality race.

A nervous wait now for Louie Hinchliffe to see if he will get one of those next two fastest finisher spots.

The positive is that was a rapid semi-final, so he has a chance.

Another sub ten seconds for the young man Louie Hinchliffe. He held his own, didn't quite get off to the start that he did in the heat but he had a good back end to the run.

Jamaica's Oblique Seville gets it! A personal best from the Jamaican sees him pip Noah Lyles across the line by 0.02 seconds.

GB's Louie Hinchliffe got off to a poor start, but he finishes strongly to come home third in 9.97 seconds.

He'll have to wait for the other semi-finals to see if that's quick enough to qualify for the final.

Here we go then! The athletes are ready.

Noah Lyles has his usual swagger as he lines up, while it's pure focus for GB's Louie Hinchcliffe, who is in the lane next to the American.

On your marks...

Louie Hinchliffe has impressed me. He has taken it all in his stride and is just enjoying the sport. And who wouldn't with Carl Lewis in your corner?

Here's how GB's Zharnel Hughes and Louie Hinchliffe made it into the semi-finals of the men's 100m.

Hughes reached the final in Tokyo three years ago, but suffered a false start and was disqualified.

He'll be hoping for another crack at the final, while Hinchliffe will be looking to cause a stir in his debut Olympics.

Get to the final. That has been the message from both Louie Hinchliffe and coach Carl Lewis ever since the British 22-year-old claimed the British title in June to secure an Olympic debut in Paris.

In the final, Lewis says, "anybody has a chance".

Hinchliffe's Olympic debut win over world champion Noah Lyles has already offered an additional chapter to his fairytale rise in 2024. But can he go another step further?

With the top two spots guaranteeing qualification, Hinchliffe has once again been drawn against Lyles in his semi-final, where he is also joined by Jamaican Oblique Seville.

It has been less than 12 months since Hinchliffe, 22, first reached out to American legend Lewis at the University of Houston. Since then, he has reduced his personal best from 10.17 seconds at the start of 2024 to the 9.95secs he clocked in becoming the first European man ever to win the prestigious NCAA Championships.

Hinchliffe has shown he thrives on the big stage, storming to the British 100m title in Manchester to book his place in Paris and then, once here, beating Lyles in a statement opening performance.

If he can replicate that in the semi-finals, it will be time to get very excited...

With the men's 400m heats done and dusted, it's time to look ahead to this evening's big event - the men's 100m.

We've got the first of three semi-finals coming up at 19:05 BST. The first two athletes from each heat the next two fastest advance to the final.

What a sensible run there from Charlie Dobson. This is his first time competing on this sort of scale and coming in as the second quickest Britain ever at the London Diamond League - I have huge hopes for him.

He did not get put off the Kenyan outside him, who went through the first 200 metres so hard that he popped his hamstring. Charlie just switched off the noise, coasted in and gave himself a little applause as he crossed the line.

Charlie Dobson taking victory - a very controlled 400m.

Most of his experience of racing is this year.

He's got a European silver medal and he's learning all the time.

Charles Dobson goes out well, falters a bit in the middle, but comes up strong in the home straight to win the final heat in 44.96 seconds.

Kenya's Ekhal Ekwam pulls up on the bend before flying face first to the floor.

Belgium's Alexander Doom and Jevaughn Powell of Jamaica also qualify in second and third.
