Back to the women's 200m heats now.

The USA's Gabby Thomas, who clocked 21.61 in winning the US trials, goes in heat four.

She's upstaged by Namibia's Christine Mboma, though, who finishes first in 22.11.

Thomas registers 22.20, finishing ahead of Aminatou Seyni in 22.72. A fast one!

After two rounds in the long jump final, Cuba's Maykel Masso still held the lead following his opening jump.

But at the start of the third round, his compatriot Juan Miguel Echevarria has moved in front with a leap of 8.41 metres. Game on!

Just the five runners in heat three.

Fraser-Pryce does look very good indeed.

She whipped round the bend - down the home straight in total control. Always focused, no messing about, gets herself round that bend.

No need to pump the shoulders and use all that power of the weight training in the winter, she can just cruise in.

A goalless third quarter in the first women's quarter-final that saw both sides temporarily lose players for ill discipline.

Argentina created the better chances but Germany had a decent spell through the middle of the quarter, and forced a great save out of Maria Succi from a penalty corner.

15 minutes remain.

Rob: Nicklaus giving Jacklin that two-footer on the last green if the 1969 Ryder Cup. ‘I didn’t think you’d miss it, but I wasn’t going to give you the opportunity’. Criticised by his team-mates but very classy.

A classy run from Shelly-Ann Fraser-Pryce sees the Jamaican take the second 200m heat in 22.22 seconds.

Then come Namibia's Beatrice Masilingi and the Netherlands' Dafne Schippers in the automatic qualification places.

On Sifan Hassan falling with 400m to go and still winning the heat:

"There was a bit of panic, she got up and she started absolutely bombing it!

"She loves the 1500m so she absolutely had to qualify by right, she didn't want to do that much work, but the fall forced her to do so. It's all still on for her."

Jamaica's 100m silver medallist Shelly-Ann Fraser-Pryce contests the second 200m heat in a few minutes time.

Meanwhile, in the men's long jump final, Cuba's 22-year-old Maykel Masso has just edged out Greece's European champion Miltiadis Tentoglou for the lead after the first round of attempts.

A 8.21m leap has set the bar.

Shaunae Miller-Uibo of the Bahamas is among the athletes in heat one as the women's 200m gets under way in Tokyo.

The Ivory Coast's Marie-Josee Ta Lou takes the win in 22.30 seconds from Miller-Uibo and Nigeria's Nzubechi Grace Nwokocha, who are the three guaranteed to qualify.

As you know, Great Britain's world champion Dina Asher-Smith will unfortunately not be competing in the Olympic 200m heats from 02:30 BST this morning.

After failing to make the 100m final in Tokyo on Saturday, the 25-year-old revealed she tore her hamstring earlier this month.

A tearful Asher-Smith told BBC Sport: "It broke my heart because I am a competitor. It is the Olympics but there are plenty other championships for me to come and kill."

She said she had been in the "shape of her life", but was then close to having to miss the Olympics after suffering the injury in her 100m British title win in June.

There is still British interest in the event, however, as Beth Dobbin goes up against Jamaica's 100m champion Elaine Thompson-Herah in her heat at around 03:18.

In the kayak singles, Britain's Deborah Kerr and Emily Lewis have both advanced to the quarter-finals.

Kerr finished third and Lewis fourth in their respective heats, and both have ended up in the same quarter-final.

That takes place at 04:14 BST and will be available on the Red Button.

Up next as far as the athletics is concerned, it's the men's long jump final from 02:20 BST.

There are no Brits in action, but it does feature world indoor champion Juan Miguel Echevarria of Cuba, world outdoor champion Tajay Gayle of Jamaica and European champion Miltiadis Tentoglou.

That's followed by the women's 200m heats and the women’s 100m hurdles final.

Argentina have dominated the first half of their last-eight match and deservedly lead at half-time, although they left it late into the second quarter to break the deadlock.

Augustina Alberttario and Victoria Granatto were both on target for the South Americans, with Germany a player down after receiving a green card.

GB's Katie Snowden after reaching the 1500m semi-finals: "That was maybe a little quicker than I wanted to run in a heat, but we've got a lot of time off now until the semi-final.

"I've got to get back now and have an ice bath, just recover as much as possible, be ready to do it all again."

Chris: Sportsmanship away from the Olympics, The Vendee Globe race, Nov 2020. Jean Le Cam turns back into howling winds and 18ft swell at night to pull competitor Kevin Escoffier out the sea after his boat broke up and sank in seconds. Well played, well played indeed.

The first qualification group in the hammer has come to an end.

GB's 2018 Commonwealth Games champion Nick Miller finished third with a throw of 76.93m, just missing the qualifying performance of 77.50m but in with a very good chance of making the final as one of the best performers.

Group B, featuring Taylor Campbell, begin at 02:30 BST.

Revee Walcott-Nolan speaking on BBC One: "I really enjoyed it, I think the race was a bit messy. I had people around me getting clipped the whole way. Then Hassan had a fall behind me and that threw me over. I think I ran a PB. I don't know if I could have done more - I feel like I'm in better shape than that, so it's annoying. I'm gutted not to make it through."
