Bryan Levell looks like a very strong contender for a medal here - fastest in the heats, and he eases to win his semi-final in 19.78 seconds.

Olympic champion Letsile Tebogo comes home in second, while Got Gout is fourth and will not progress to the final.

Olympic champion Letsile Tebogo is up in the second semi-final.

The sprinter from Botswana is up against the fastest qualifier – in-form Jamaican Bryan Levell – as well as the intriguing 17-year-old Australian record holder Gout Gout.

Gout yesterday said he enjoyed “running against the big dogs” when third in his heat. Can he continue to make his name tonight?

Georgia's heat went exactly how we thought it would. It was all about the last 200m, that's when she wants to hit the front. Really significant for me, it shows what character she has. She wanted to cross the line first and it was a comfortable win.

No issues for USA's Kenny Bednarek, he strides to victory in his semi-final with a time of 19.88 seconds.

Alexander Ogando of Dominican Republic comes home second to also earn his place in the final.

Two-time Olympic silver medallist Kenny Bednarek controlled his heat and said afterwards: “This is the best I have ever felt.”

We shall see - he's the big name up in semi-final one.

The top two in each of the three semis, plus the two other fastest athletes, progress to the final.

Morgan Lake has been in excellent form of late and the British athlete has cruised her way through qualifying in the women's high jump.

The 28-year-old is one of eight athletes to finish joint-top of the standings, having made a mark of 1.92m.

16 progress in total to Sunday's final.

GB's Georgia Hunter Bell, speaking to BBC Sport after qualifying for the semi-finals of the women's 800m: "We have been out in Japan for a long time, so it felt like Christmas morning getting out on track. The rounds are hardest in 800m, so I have to take it race by race."

On choosing to race 800m rather than 1500m: "Doing 800m is the right decision. I feel like I have really got something to show, I have a high ranking, and with my team mate this was the year to do it."

Zharnel Hughes is the British name to look out for in the men's 200m semi-finals after team-mate Toby Harries failed to qualify.

Jamaica's Bryan Levell came out top of his heat and posted the best time overall, covering the track in 19.84 seconds.

Fellow Americans Courtney Lindsey and Kenneth Bednarek qualify in second and third place respectively, followed by Noah Lyles.

Zimbabwe's Tapiwanashe Makarawu and Letsile Tebogo also finished first in their heats, while South Africa's Wayde van Niekerk looked very good in his qualifying race.

It is all to play for.

Jamaica's Natoya Goule-Toppin finishes first in heat seven, but there was plenty of action throughout.

Australia's Jessica Hull appeared to be tripped early in the race, and will have to wait now to see if the referee will advance her through to the semi-finals.

Botswana's Oratile Nowe takes second, and Canada's Maeliss Trapeau clinches third to qualify for the semi-finals.

World Indoor champion Prudence Sekgodiso of South Africa also pulled up with what appears to be an injury half way through the race, and she will not feature in the semi-finals.

Cuba's Leyanis Perez produced a leading jump of 14.66m in qualifying on Tuesday. She also won the world indoor title in March and has five of the top six jumps this year.

Venezuela's Yulimar Rojas jumped a season's best of 14.49m. She won gold at the Tokyo Olympics and is a seven-time world champion indoors and out.

Current Olympic champion Thea LaFond of Dominica qualified in fourth place and Jamaica's Shanieka Ricketts also makes the final.

Let's take a look at what's coming up over the next few hours (all times BST):

12:55 - Women's triple jump final

13:02 - Men's 200m semi-finals

13:24 - Women's 200m semi-finals

13:45 - Men's 800m semi-finals

14:10 - Men's 400m final

14:24 - Women's 400m final

It's gold for Keshorn Walcott of Trinidad & Tobago!

The 32-year-old led going into the final round and none of the other five remaining competitors can better his best of 88.16m with their final throws.

He takes a final throw knowing the gold is already his.

Curtis Thompson of the United States finishes third having fouled with his last three throws, while Olympic bronze medallist Anderson Peters of Grenada takes silver in Tokyo.

Rain had been forecast and there was supposedly even a chance of thunderstorms this evening.

Things haven't got quite that serious yet, but the rain is coming down pretty hard now and, for the first time during these championships, there is a breeze in the stadium.

They are conditions which the British athletes should feel much more at home in, with the temperatures dropping to a relatively cool 26C.

The fourth placed runner in heat six, Renelle Lamote of France, finished in 1:59.32.

Which means, sadly, GB's Jemma Reekie is pushed out of the fastest loser places and is eliminated.

Great Britain's second medal prospect Georgia Hunter Bell advances in heat six.

Claudia Hollingsworth of Australia takes an early lead, but Hunter Bell eases into first place with 200m to go and looks very comfortable coming down the home straight, finishing in one minute 58.52 seconds.

Gabija Galvydyte and Hollingsworth take the other two automatic qualifying spots.

Neither the world nor Olympic champion will top the podium for the men's javelin in Tokyo.

Arshad Nadeem of Pakistan, victorious in Paris last year, went out in 10th after the fourth round having managed a best throw of 82.75m.

Neeraj Chopra of India, the reigning world champion, couldn't improve his best throw of 84.03m in the fifth round and finishes eighth, with only six athletes advancing to the final round.

Keshorn Walcott of Trinidad and Tobago leads, with Anderson Peters of Grenada in second.

Jemma Reekie finished in 1:59.35 - she is the third of the three fastest losers at present.

She must hope neither of the fourth placed finishers in the final two heats go quicker than that, in order for her to progress to the semi-finals.

Jemma Reekie was overtaken in the final 200m and finishes fifth in her heat.

It was a quick race though, so she is currently one of the three fastest athletes not to finish n the top three of their heat - which would allow her to qualify for the semis.

There are two heats to come, and the Brit faces a nervous wait.

Jemma Reekie has been caught!
