Nethaneel Mitchell-Blake is through in second and 20.35 seconds.

What about Adam Gemili though?

The times are dripping through...

We had to wait a long time for Adam Gemili's time to clog through the system.

Finally the hamsters stop spinning in the wheels and we have a number. He is third in 20.46.

That puts him down as the fastest loser so far across the first two semi-finals.

There is one more to go through. It contain's team-mate Nethaneel Mitchell-Blake as well as the swift Alex Wilson of Switzerland.

Gemili needs for the fourth finisher to be slower than his time...

Adam Gemili got out of the blocks well and he committed to the first 30m, but the guys on either side of him just burned past him and in the end Adam really had to fight for that third place.

He'll be very frustrated with that because he won't know why he's struggling there. You can see him shaking his head, he'll be wondering what is going on.

Adam Gemili has shown great potential and he's had a lot of injuries, but when you're injured you have to alter your training so you can stay fit.

I just wonder if he still believes if he has that massive potential that he showed at London 2012.

Spain's Bruno Hortelano takes the victory, but Great Britain's Adam Gemili is edged out of second by Italy's Eseosa Desalu.

Gemili will have to wait to see what his time can do for him in the fastest loser spots.

Gemili is repeatedly shaking his head in the warm-down area. He doesn't seem to hold out much hope.

Leon Reid was just outside his personal best there, that's exactly what he needed to do.

Next off the ramp, in the second semi-final, is Great Britain's Adam Gemili - who finished just a whisker off the Rio 2016 podium, but was hindered by injury last year.

The from man in the second semi-final is Spain's Bruno Hortelano.

Adelle Tracey has been on the cusp of a sub-two-minute run all season and that smile of hers says it all. She'll go into the final full of confidence.

Shelayna Oskan-Clarke is not looking as fluid as she normally does, she's having to work a bit harder than usual, but come the final she'll be there, focused.

Britain's Adelle Tracey speaking to BBC: "I am so happy with that. I have had it in my sights this season so I'm really pleased I was able to do it."

Finalist Shelayna Oskan-Clarke: "We had the advantage of seeing how the first semi-final had gone so we knew if it was a quick race the fastest qualifiers would go through.

"It's what we want."

Two clear of the rest.

Ireland's Leon Reid was very composed and controlled, coming home second in 20.38.

Next up on track is the men's 200m semi-finals.

The first of three semi-finals contains the world champion Ramil Guliyev of Turkey.

He should comfortably wrap up one of the two automatic spots, but may well come under pressure from Ireland's Leon Reid.

That's a huge moment for Adelle Tracey. She's been knocking on the two minute barrier for so long and she's put in a really strong, committed race. It was a genuine grin on her face at the end - she'll be so happy with that.

Renelle Lamote ran this race so well - she really controlled it and strung out the other runners behind her.

That is the first time Adelle Tracey has smashed two minutes. What a time to do it! Three women into the final!

Big, big for Adelle Tracey.

The 25-year-old breaks the two-minute barrier for the first time in her career, coming home in 1:59.86 behind France's Renelle Lamote.

Shelayna Oskan-Clarke battles home fourth, but a season's best time is more than good enough to get her into the final.

That was really comfortable there from Lynsey Sharp. She knew she just needed to stay relaxed and qualify. The whole time her eyes were on the screen. Sharp is into the final now so she has got to be thinking about medals. It was a disappointing Commonwealth Games for her but she has to be thinking about medals.

British duo Shelayna Oskan-Clarke and Adelle Tracey are up against France’s 2016 European silver medallist Renelle Lamote in the second semi-final.

Both Brits have season's best that are good enough to take at least one of the fastest loser spots if they carry them into the top five.

Rock solid from Lynsey Sharp, who qualifies with time and position to spare.

The Scot is through in second place, behind the defending champion Nataliya Pryshchepa in 2:02.73.

The first three from each of the two semi-finals get an automatic slot.

Britain’s two-time European champion Lynsey Sharp is here. When Laura Muir turned up and put the cat among the pigeons by winning the 800m at the British Championship, it seemed like she might not be.

Reigning champion Nataliya Pryshchepa of Ukraine is in lane 4. The 2016 bronze medallist, Sweden’s Lovisa Lindh, is in lane 1.
