This will be very, very, very competitive but it's always about getting that baton around.

There are superstars everywhere we look here. Noah Lyles asks the crowd for more noise as he emerges under the lights.

We've already seen one USA team be disqualified in the relays tonight.

Here's the men's 4x100m relay line-up with their qualification times.

2. Brazil 38.19

I think they've had a little bit of disruption and there's been a few things going on within their group but I think they actually look really great. They've got the likes of Eugene Amo-Dazie coming in looking really strong.

There's that cross-over with bringing in some new talent and training them up and getting them used to that squad experience which I think is great for the future of the relays.

Great Britain's Ben Pattison speaking to BBC Sport's Jeanette Kwakye after winning a bronze medal in the men's 800m: "I don't know why you're interviewing me. I can't think of anything to say! I crossed the line and I feel like I'm going to wake up in a minute. All day I've had people telling me I'm going to medal and then half way through the day I started to believe it.

"Going into the race I thought I don't want to leave with any regrets. I got out hard. It was a slow first lap which suits me and in the last 100m I said to myself I've got a medal here. I just kept pushing. To the line, it was a battle of who wants it more and I came out on top. I don't really know what's going on right now."

Duplantis will just have to break the world record at the Olympics next year...

Last chance for Mondo...

Great Britain's 800m BRONZE MEDALLIST is giving one of the great interviews to BBC TV right now.

He's talking about his mate writing a song about him!

SO CLOSE.

I think everyone here thought Armand Duplantis had made that. Hands on heads everywhere. It's there, he knows it is.

So, so close.

The Swede has his feet over the bar but cannot contort his body to get it over too.

Come on, Mondo...

This really is the Armand Duplantis show now.

All eyes are fixed on the pole vault.

This is how the Swede likes it. The attention fixed on him, just as it was at last year's World Championships.

In Eugene, he broke the world record with his second attempt. Here he comes. Silence falls.

We still have the sprint relays to come and the big names - Shericka Jackson, Sha'Carri Richardson, Zharnel Hughes and the rest are on the warm-up track.

Next up is the decathlon's final event - the 1500m.

Canada's Pierce LePage is in gold medal position as it stands and it's a big lead of 145 points - 20-odd seconds in terms of time.

Too much surely?

Not to be for Armand Duplantis - not yet at least.

Having beaten off all of the competition he's now set the bar at 6.23m - 1cm higher than his own world record.

He clatters into the bar on his first attempt. He'll have two more tries.
