CJ Ujah is setting his sights on making it to the final in his home World Championships.

"The crowd was amazing. London, the World Championships...it can't get any better than this," he tells BBC Sport. "Hopefully I can make it to the final. I've got to keep my head down and keep improving."

On room-mate Reece Prescod advancing: "He's a good kid and I'm sure he'll probably smash his personal best again. It's good for British sprinting."

American veteran Justin Gatlin - twice banned for doping - is given the bird on the startline ahead of heat five.

Not the whole crowd, but there was a decent smattering.

Trinidad and Tobago's Keston Bledman and South Africa's Thando Roto are possible contenders for this one.

What better way to mark your first appearance at a World Championships than with a personal best. No wonder Reece was so happy afterwards.

CJ really nailed it. All season he has been doing these type of performances. He will raise his game going through the rounds I am sure.

Safe and sound from CJ Ujah. She strides through in second in a time of 10.07 seconds.

He is sandwiched by China's winner Bingtian Su and the United States Christopher Belcher in 10.03 and 10.13 respectively.

All looked comfy.

You got it Boris. Right here on the BBC Sport.

I think Ujah can medal. The season he's had and consistency he has shown, finishing ninth at the Olympics last year showed him what was possible. He went away and worked in the winter and he even talks differently in interviews now. I think he can go 9.9 low...

The fourth 100m heat.

It features the fastest Briton in the world this year and the winner of three Diamond League meetings - CJ Ujah.

Look out for Christopher Belcher on the outside. The American is fourth fastest in the world this year in 9.93 seconds.

Reece Prescod speaking to BBC Sport after qualifying for the 100m semi-finals:

"It's crazy. It's the first time I've been in the stadium and when I walked out I saw so many people. Hopefully I can do the same tomorrow. In the morning I was feeling a bit nervous but come lunch I was pretty chilled. I feel like it is coming [sub 10 seconds].

Great Britain's Holly Bradshaw makes a solid start in the women's pole vault, clearing her opening height of 4.50m at the first attempt.

If she does the same at 4.60m she will have a free pass into the final.

A very strong performance by Reece Prescod. I was wondering how he was feeling and whether he was going to be anxious on the line. He got out well and put himself in a very good position. He did exactly what was necessary and he was rewarded with a new personal best.

A brilliant performance from Reece Prescod on the inside. A fine run by Julian Forte in 9.99 seconds, the fastest of the night. Nothing short of a lifetime best for Prescod.

A new personal best of 10.03 for Reece Prescod in third behind Ivory Coast's Ben Youssef Meite and Jamaica's Julian Forte.

Akani Simbine will have to wait to see if his time of 10.15 is good enough for a fastest loser spot in the semi-finals.

We go again in the 100m.

A solid heat coming up.

British champion Reece Prescod lines up against the ultra-consistent Akani Simbine and Ivory Coast's rapid Ben Youssef Meite.

A big upset in the long jump.

Olympic champion Jeff Henderson is not going to be coming back for tomorrow's final.

His final jump is a disappointment at 7.74m and that is just not going to cut it.

A really great performance by this young man. I agree that 200m is where he is going to go because he has a beautiful, silky smooth technique. I'm going to remind you of this guy's age. He is just 18. Good stuff from the youngster.

The heir apparent?

Is Christian Coleman the man to take over from Bolt in the 100m? It was certainly a solid introduction to the championships.

Japan's 18-year-old Abdul Hakim Sani Brown takes victory in 10.05 with Yohan Blake, perhaps a little tentative out of the blocks, second in 10.13.

Blake pulled out of a Diamond League meeting a fortnight ago in Rabat after suffering a groin tweak.
