Robin Johnson: Staggering that Jason Roy is still being picked by England. At this point it’s just cruel to see him trying to remember which end of his bat to hold.

Solid start from Sam Curran as Quinton de Kock and Reeza Hendricks pick up a single apiece.

The bleach-blonde Sam Curran has the white ball in hand and is at the top of his mark. Quinton de Kock is on strike.

"Play" says umpire Martin Saggers.

Buttler opting to bowl first does two things. It puts pressure on South Africa and allows England to test a few things ahead of the World T20.

England's players are striding out at Sophia Gardens as the sun starts to peep through. Quinton de Kock and Reeza Hendricks will open the batting for South Africa.

Bristol was the best white-ball game I've seen this summer. It had a bit of everything. The surprise was seeing a young player who you had never really heard of in Tristan Stubbs.

To see him come out and give you that youth, vibrancy and ball-striking ability - it really whets the appetite.

The weather watchers out there will be relieved to see the forecast looks pretty good this evening.

Cloudy skies over Sophia Gardens at the moment as fans make their way into the ground, but there's only a slight chance of a shower and certainly nothing to impact on things in a major way.

Liam Livingstone, speaking to Sky Sports, has been talking about who is the biggest of England's big hitters.

He said: "It was good fun watching it last night. Jonny Bairstow and Moeen Ali seized the opportunity and put their foot on the throat. We want to take the momentum from last night. There's different dimensions here, so we reassess conditions and go again.

"Mo was going on about his sixes last night. It's great fun and the boys take the mick of out each other about the distances. Six hitting is something I pride myself on and it's given a role in this team. It's something I have worked hard on.

"Everyone backs themselves as the biggest hitter - personally I wouldn't want to go up against Jos Buttler. He has more strength, I probably have a bit more bat speed."

There's live radio commentary of this evening's match on BBC Radio 5 Live Sports Extra. The Test Match Special team will on air from 18:20 BST and you can listen online.

Later on tonight you can also watch highlights of the match on BBC Two at 23:45 via the iPlayer.

South Africa captain David Miller: "We probably would have bowled as well. There's a big boundary on one side so hopefully we can use that well.

"We're going with the same team again. We're back on it and ready to go."

England captain Jos Buttler: "You can see the conditions, we like to chase and it is different ground dimensions to yesterday so we will have a look with the ball first.

"As a team it is about parking last night, being adaptable to the conditions and playing accordingly."

Jos Buttler gives the coin a flick and David Miller calls heads. It has come down a tail.

"We're going to bowl first," Buttler says.

Both teams are unchanged from yesterday evening.

About last night...

England had some fun in Bristol didn't they?

They hit 20 sixes, the most they have ever hit in a T20 game, while Moeen Ali's 16-ball fifty was the fastest ever by an England player.

That's before we even mention Jonny Bairstow's brutal 53-ball 90 which included eight of those sixes.

Let's hope for more of the same this evening across the Severn Bridge in Cardiff. Welcome to live text commentary of the second T20 between England and South Africa.
