Cook hits 115 on South Africa debut
Amla 109 - adds 202 with Cook
Bavuma 32*, De Kock 25* from 274-5
Two wickets for Moeen
England lead 2-0 in four-match series
Ben Stokes is given the ball for the last over of the day. But it's South Africa who are finishing this topsy-turvy day with their hand on the tiller, and Bavuma has the final word by square-driving for four. That's stumps.

"It has been a really enjoyable day's cricket. It is always nice when someone comes in and does well in their first Test."
Bavuma knocks a single and that brings up a rapido 50 partnership between these two. Just when England seemed to have the momentum, these two young thrusters have pinched it.

"That’s an exquisite shot, he really does play that well. There was a bit of Tendulkar about that."
Bavuma keeps the momentum flowing South Africa's way with a brace of fours. The first is brutal, crunched down the ground; the second is pure eye candy: getting his foot to the pitch of the ball and unfurling a velvety drive through the covers. So good-looking you could pin it to a teenager's bedroom wall.

Greg: With the new ball in their hands our bowlers have lost their heads. Poor bowling.
De Kock puts the hammer down! The cherubic stroke-maker is getting his ODI groove on. He takes Jimmy Anderson for a trio of fours: punching down the ground, slashing off the back foot and then clobbering a pull over midwicket. This partnership, in no time at all, has accumulated 40.

The 29-year-old all-rounder has captained Zimbabwe in 62 of his 196 ODIs and 18 of his 41 Twenty20s.
Although he has been Test captain since Brendon Taylor quit internationals after the 2015 World Cup, he has not led the side because Zimbabwe have not played a Test since November 2014.
Chigumbura said:, external "I still believe I have more years of playing in me and of winning games for the team."
De Kock clips Broad into the leg side for a single. Meanwhile, up on the balcony, Jimmy Cook - father of Stephen - has cracked open the bubbly.

"England need another wicket to make it a comparable day. They gave them a 100-plus start before they have clawed it back a bit."
Bavuma pokes through backward square for a couple. The floodlights are on...
What do you reckon - are we having that from De Kock? How do you hurt yourself walking the dog exactly? It sounds like one of those excuses you'd make your mum write in a note if you wanted to get out of games. Has anyone from Cricket SA checked what he was up to during the third Test? He's back now though, and announcing himself to Stuart Broad with a crunching pull through the leg side for four.

"Anything under 400 will be a massive disappointment to South Africa. After lunch, England would have said if we could bowl them out for under 400 then we have done a fantastic job."
Quinton de Kock, you may recall, missed the last Test with one of the more bizarre excuses in cricket history - he apparently hurt himself walking the dog. It's just as well Dane Vilas didn't make a hundred in his absence - he might have stubbed his toe kicking the poor mutt. De Kock defends to mid-on for a single.

Charlie Latto: In the space of a day we've gone from being a great team, to having an awful bowling attack, back to being pretty good again.
Whoah there, some absolutely prodigious movement from Stuart Broad, wide and De Kock can't resist a dart - he's lucky not to snick as it curves into the hands of first slip. The average first innings total at Centurion, I'm told, is 350, which makes this pretty much a par effort by South Africa so far. Mind you, there's work to do yet to get up to that total.

"It is a big moment for England. If they can nick a couple here, and get them seven down, they can go to bed thinking, 'we can have a big lead here'."
SA 287-5
Yes, unsurprisingly, the new ball is taken straight away, and entrusted to the craftsmanship of Jimmy Anderson. Plenty of shape for the Lancashire seamer early doors, but Bavuma responds with some geometry of his own, pinging a four straight through point.

The wicketkeeper-batter made history in October by becoming the first woman to play Australian first-grade cricket, appearing in two matches for Adelaide's Northern Districts under the captaincy of Australia batsman Mark Cosgrove.
Taylor told BBC Sport: "It was intense, probably one of the best experiences of my life.
"The guys were absolutely brilliant. It was the hardest thing I've done on a cricket field, but equally as rewarding."
England's Sarah Taylor believes her own game will improve enormously from her experience of playing men's cricket in Australia.
