Cook 67*, Root 31*
Rabada removes Hales & Compton
Compton lbw to one that kept low
SA: De Kock 129*; Stokes 4-86
England lead 2-0 in four-match series

While England have been winning a thrilling Test series in South Africa in front of plenty of empty seats, Australia's domestic Twenty20 tournament has drawn record crowds and huge TV audiences.
Is the hype justified? Should England follow suit? And what does it all mean for Test cricket?
So three drops today - and either one or two yesterday, depending on how harshly you judge that one that went low between wicketkeeper Bairstow and first slip Cook yesterday. Whatever your opinion, it's not good for England. Piedt looking solid as he keeps out a Broad maiden.

"Cook should have caught that - it was straight at him. England have got Cape Town-itis today - they can't hold anything."
SA 428-8

"It will be very interesting when South Africa do bowl on this pitch what they get out of it. It will be a big innings for Alex Hales at the top of the order."
Broad thundering in, nice and full, targeting the stumps. Where's that one gone? De Kock squeezes a yorker into the leg side and has little idea where the ball is as he scampers a single.
India chased 331 to win the fifth and final ODI against Australia in Sydney by three wickets.
Manish Pandey finished unbeaten on 104, his maiden ODI hundred, as the tourists got home with two balls to spare.
Australia, who win the series 4-1, were earlier taken to 330-7 by centuries from David Warner and Mitchell Marsh.

De Kock gets moving again after lunch with a single to deep cover, and Piedt manages one of his own off the last ball of the over.

"The pitch has played alright and there has been no real swing or seam. There have been a couple of good partnerships this morning. Dane Piedt will have a lot of bowling to do but he has got some batting to do yet."
Stuart Broad has the ball in hand. De Kock facing.

Thanks Stephan. With 98 runs in that morning session, you'd have to say it belonged to South Africa. And England still have work to do - Quinton de Kock, unbeaten on 85, is the man they'll want.
The lunch break is nearly done. Justin Goulding has scooted into the seat next to me. He's here for the afternoon session.

Dan Thwaite: Loved listening to Jack Bannister talk cricket. I bet him and Richie Benaud are having a right good cricket chat now.

The Guyanese left-hander, 41, made his Test debut in 1994 but was dropped after West Indies' home series against England in May 2015.
With 11,867 runs from 164 Tests, he is the Windies' second highest run-scorer and the seventh highest of all time.
Chanderpaul also played 268 one-day internationals - where he scored another 8,778 runs - in five World Cups, and 22 Twenty20s.

Mike Procter on being a match referee: "He oversees the game representing the ICC and you go through a few games where nothing happens. Then the ball tampering of Pakistan at The Oval in 2006 was the first time in my life where I felt I wasn't in control, I couldn't believe a Test match had been stopped like it was.
"The ECB wanted to put an announcement saying the match was over but I said not to. I was trying to speak to the Pakistan team, trying to resuscitate the match."

My parents used to take me to Gloucestershire Sunday league games in the late 1960’s. There was always a wonderful sense of anticipation when Mike was batting or bowling. He inspired my very modest most club cricket career but a lifetime love of the game.
I was lucky enough to be at Southampton for the B&H game when he took his hat trick v Hampshire . One of those sporting moments that you never forget. Surpassed perhaps by Swindon Town beating Arsenal in the 1969 League Cup final.

Former South Africa all-rounder Mike Procter: "I am a great believer in coaching around natural ability, no two bowlers or batsmen are exactly the same. Don't interfere with a natural action."
