It's been a little bit sloppy from South Africa in the field.
It looks like the pressure is boiling over a bit into the field.

It's been a little bit sloppy from South Africa in the field.
It looks like the pressure is boiling over a bit into the field.
There's the record powetrplay score for England.
Their highest total in all T20s is 267-3, if you're wondering.

Fastest 50s for England in T20Is:
So England need two runs from this final over of the powerplay to make it their best in T20s.
It has been thrilling from the very start...

A quite brilliant - and sometimes brutal - fifty from Jos Buttler.
Buttler hits rapid fire fifty as England dominate against South Africa
A fifty from 18 balls - reached with his fourth boundary in succession in this over.
Buttler looks to the sky in memory of his dad.
I can't keep up as Jos Buttler strikes two more fours. The second could have been caught by the sprawling fielder at mid-on.

When Jos Buttler's like this, I don't know where you bowl at him to be honest.
See ball. Smack ball.
Kieran's going to have to update his record books. Jos Buttler has 41 from just 15 balls.

England's highest powerplay score in a T20 is 89-3 vs South Africa, at Mumbai 2016.
Two more fours to end the over means it's 20 from that one, after 23 came from the previous.
The change to spin did not work. The Old Trafford crowd, meanwhile, are being whipped into a Viking Thunder Clap.

It looks a fantastic wicket. The ball is skidding on.
The ball is being hit straight and square.
That's always the sign of a good wicket.
This is brutal hitting. Spinner Bjorn Fortuin is pumped over long-off by Jos Buttler now.

England seem to have an answer for everything South Africa are throwing them at the moment.
Salt 26, Buttler 20
And it gets worse for 31-year-old Lizaad Williams.
After he manages to get Jos Buttler down to the other end, the seamer gets too close to the hip of Phil Salt who swings him to the fine-leg boundary. The final ball is edged for four too meaning it's 23 from the over.

Strange option to go in the third ball of the over.
You tend to save that bouncer for later in the over.
And that fourth ball is strange too.
It's a horrible time for a bowler to be bowling right now.
Two wides follow from Lizaad Williams. England have their opponents' heads in a spin early on.
Timed for six more! This is the best shot so far.
Lizaad Williams has a Jos Buttler-shaped problem.

That's a proper welcome to Old Trafford for Lizaad Williams.
Jos Buttler has absolutely smoked that.
Lizaad Williams meet Jos Buttler.
South Africa's seamer comes on after Marco Jansen's first expensive first over and is smashed for six by the pulling Buttler.
