It will be interesting to see how the bowlers react.
South Africa will have nothing to lose here, but how will the bowlers look after their own game?

Target 305
Aiden Markram is seeing it a little better.
He launches Luke Wood for six down the ground, before edging streakily past the keeper for four.
Target 305
Fair enough, Ryan Rickelton is swinging at everything.
The only problem is he's not hitting it. One boundary is thumped down the ground, but he just swipes at thin air for the other five balls.
Make that four dots in a row!
Here is England's history-making moment.
England reach 300 mark to post their highest ever T20 total
Just who you want to see when you're chasing 305 in a T20.
Jofra Archer starts with a dot.
Target 305
Good recovery from Luke Wood, with just two more coming from the over.
They need to be going at double that run-rate...
Scott Read
Test Match Special commentator
What a hit for six. We've seen some terrific batting tonight and that shot was up there with the very best of them.
Target 305
Aiden Markram got the memo!
An effortless flick off his pads for six.
Yep, this is a good pitch.

Is “Anon 19.37” gonna honour his bet to dress up as the best suggestion for the entire day tomorrow at wedding if England score 300? Dress up as a stick of rhubarb!

Right, Anon, let's get the ball rolling: Wilma Flintstone.
Matt
Target 305
Dot ball to start.
Can't afford too many of those, lads.
Over to you, Ryan Rickelton and Aiden Markram. All the best.
Jos Buttler speaking to Sky Sports:
"Three hundred, I never thought I'd see that. Unbelievable. That was great and obviously we're delighted to get that many."
On conditions at Old Trafford: "It's a really fresh wicket, hard wicket and not much in it for the bowlers. Salty put so much pressure on them straight away and carried that on into the power play."
On message to bowlers: "See how we go. It will be interesting to see how slow Adil Rashid bowls with 300 on the board. Obviously it's a lot of runs, but we respect the game. We'll go out there and try and bowl and execute well."
That was absolutely bonkers.
Spare a thought for the bowlers - look at these figures:
Thanks, Matt.
So... what just happened?!
'Breathtaking batting' - Salt hits fastest England T20 century
You're not the only one, Jos.
I'm off for a lie down. Here's Ffion Wynne to take you through South Africa's glorious victory/chase.
"300? I never thought I'd see that," says Jos Buttler.

Phil Salt deserves the applause. What an innings.
Everyone is so elated for him.
What a feeling to walk up those stairs and be surrounded by those lads high-fiving him.
It's only two to finish.
Harry Brook pushes Phil Salt forward to walk off on his own.
He finishes 141 not out from 60 balls - the highest score made by an England player in T20 internationals.

The crowd are on their feet as if someone has scored a match-winning hundred.
