Viljoen back into the attack, but he's not got his radar as soon as his did in his first spell. 

Compton has moved up through the gears slightly, driving and then pulling consecutive deliveries for four, edging his strike rate tantalisingly close to 40.

I'd been wondering why people in the crowd have their beers in a plastic cup with a handle, almost like a measuring jug. 

The reason has just become apparent, as one spectator is shown carrying an estimated 16 (sixteen) beers back to his mates, using the handles to stack them.

"Whoever gets a hundred in this match will be on the winning side: it's got that feel to it."

Remember when South Africa kept playing and missing yesterday? England have started doing it today. Compton's just flashed at a wide one and missed. 

What's going through his mind when playing those shots? They're entirely out of kilter with how he usually plays. It's not as if he's had success with it so far this innings, either.

Just one off the over, an ambitious single, but Root is quick enough between the wickets to get there in time.

"This is tense, good cricket. It's not rocket science - whenever you can get the bowlers in the game, you get a wonderful contest. Suddenly the batsmen realise they could get out and try and score runs quicker. It makes for a better spectacle."

Joe Root looks in a touch of discomfort as he wears two consecutive deliveries from Morkel, both banged in short. 

A delicious cover drive from Root for four keeps the scoreboard ticking over, though.

"That was straightforward, a regulation catch which carried nicely. That's the first ball which has created a problem for the batsmen since lunch."

Chris Morris is going to be hugely frustrated with that over. A dropped catch, an edge for four, and then a beautiful stroke from Compton driving for four. 

This is an absorbing battle at the moment.

With one shot, Compton doubles his score, cutting a short one from Morkel through backward point.

Michael Head: Tim, I also think of 'that' Chris Morris. Need Peter O'hanraha-hanrahan behind the stumps too.

You've lost the news, Peter! 

England trying to wrest the initiative back from the South African bowlers here. 

By 'England', I mean 'Joe Root', who has the confidence to punish the bad balls, pulling Morris in front of square for four. 

Morris lets out an impressive grunt when he releases the ball. It's not quite Steve Backley-esque, but let's say World's Strongest Man.

"I love Morne Morkel, he's a lovely lad. He just needs one of the experienced players to stand next to him at mid-off and pitch it up. He'll get more wickets that way.

"That ball which went for four was tripe, a lollipop."

Best form of defence is attack, and all that. 

Root drives Morkel back down the ground for two, then lifts a short wide one almost all the way for six, falling just short of the rope. 

And then, as if to suggest that he wants to face a bit more of the bowling, he steals a single off the last delivery.

Morris gets a bit of swing as he finds a leading edge from Compton's defensive in an otherwise uneventful over from Chris Morris. 

Am I the only one who constantly thinks of the Brass Eye frontman whenever they hear Morris mentioned?

"Nick Compton will be a key player for England if he can do what he did in Durban. He can stick in, wear down the bowlers and take the shine off the ball. He can be the glue who holds it all together."

A few of you have been contacting us to ask about this... 

A penny for Root and Compton's thoughts over lunch. 

I was about to say that they'd been more watchful since the break, but Root chased after the last delivery that bounced up wide outside off stump, but couldn't get any bat on it.
