What a great run by the American quartet, but this is a dark day for the Netherlands.
Mixed 4x400m relay
What a crushing 15 minutes for the Netherlands.
First Sifan Hassan hit the deck with 25m to go. Then Femke Bol did exactly the same although, as far as I can see, there was no contact in that final race.
Bol just stumbled as she desperately reached for the line.

The Dutch will not get a medal at all there because she has dropped the baton.
Mixed 4x400m relay
Bol dropped the baton on the line so the Netherlands did not finish.
It was Czech Republic who came through for bronze.
Mixed 4x400m relay
And that means Great Britain come through to take silver with Femke Bol on the ground, having led with metres to go.
Mixed 4x400m relay
More drama!
Femke Bol tipped for a golden week in Budapest ties up horribly in the final stages.
She's desperately clutching for the line with the USA closing in and then falls to the track...

Mixed 4x400m relay final
Away we go!
The Netherlands and USA are two of the favourites here.
Mixed 4x400m final
We have one more final to come. It's the mixed 4x400m.
The British team of Joe Brier, Laviai Nielsen, Rio Mitcham and Yemi Mary John were the second-fastest qualifiers.
Lewis Davey has come in for Brier for the final.

Former women's marathon world record holder on BBC TV
There was contact but whether that caused her to fall is another question. It will certainly fire her up. If anybody can out that sort of bad luck behind them then it is Sifan Hassan. She is very good at seeing the bigger picture. She is very rare and will be able to put her head on the pillow and come back and put all of that into the next race.
Women's 10,000m final
To be fair to Sifan Hassan she has taken this very well.
She just smiled and shrugged as she got up from the track to cross the finish line.
Michael Johnson
Four-time Olympic gold medallist athlete on BBC TV
Sifan Hassan felt the contact and I think she tried to adjust her stride. That's what caused her to fall. You can't adjust your stride when you're moving at that speed and you're fatigued.
Women's 10,000m final
Sifan Hassan speaking to BBC Sport after the 10,000m race: "I got pushed. The girl was running on the outside and I get blocked. But, what can you do? It is sport, it can happen.
"Maybe I'm crazy, but I felt a push and I'm in high speed so I couldn't control my legs. It doesn't really matter to me. It just happens.
"I have two more races to go, we will see what happens."
Women's 10,000m final
"What can I do? It is sport. It can happen," adds Sifan Hassan, seemingly playing down the prospect of an appeal.
Women's 10,000m final
Sifan Hassan has just been speaking to BBC Sport. She says she thought she was pushed in the closing moments of that 10,000m final.
VAR anyone?
Steve Cram
Marathon commentator on BBC TV
There's a smile on the face of Hassan. I don't think that was fatigue. She had the gold medal half way round her neck. At least the silver medal.

John: What a finish to the women's 10,000m!
Men's shot put final
We said it from the very first throw and now Ryan Crouser is enjoying his crowning moment as he steps up for the final throw of the competition - the medal already his.
Can he end on a high?
OH YES HE CAN. He produces a huge 23.51m, just 5cm short of his world record.
