Flying bat alert! James Taylor, trying to cut Viljoen, has let go off the blade and sent it flying to mid-wicket. Laughs all round, but spare a thought for short leg Temba Bavuma. He almost took a bat to the bonce. Bavuma returns the bat and I think challenges Taylor to a fight. Strawweight, I think.

If you were reading yesterday you'll know that Marc Higginson asked his council for a new bin. He's had a reply. He can pay £27.50 or have a man come round for an assessment. What's he going to do, live in the bin like Oscar the Grouch? Pop up every time Higgo puts his empty pizza box in? The mind boggles.

On the field, Root twice takes Rabada through mid-on for boundaries. Punch and counter-punch. Soak up the punishment, hit back.

They've bowled well today, good lengths, good lines. They've been really excellent. 

The players are just taking drinks. Root and Taylor might need something stiff. Hardus Viljoen is having a can of spinach.

There was a smoothness about that shot from Taylor - he just punched it away towards the boundary. A lovely way to bring up your first boundary.

Here's a show, the hulking Viljoen to the tiny Taylor. It's like an under-13 playing his first match of senior cricket. Then again, Taylor will be used to being outsized and he leans into a sweet cover drive. For every little win is a reminder that danger lurks - this time it is in the shape of one the beats the outside edge. It's compelling stuff to watch.

What is going on out there? England look a little spooked by the spice in this track. Compton had no need to play, James Taylor is hopping around and Joe Root has just slashed and missed. England need to get their nose to the grind, because this match could be lost by tea.

Sipech: Straight Out, Compton.

Right, I know what you're thinking. 'Shemilt comes on and England lose a wicket'. Let's nip this in the bud right now. It's nothing to do with me, there is no twist of fortune linked to the change of the live texter. In fact, blame Nick Compton - that was a flat-footed prod. James Taylor is the new man.

Rabada looks a magnificent prospect, he gets that little extra bit of bounce. 

Compton will be disappointed with that. He just dangled his bat, and dabbed at the delivery. 

Simon Godfrey: I'm sat here working on a document and there's a guy at the cricket in SA carrying 16 beers to his mates, where's the justice?

One off the over. Viljoen reminds me a bit of Kallis as he bustles up to the crease. 

Although it slightly troubles me that he bowls with a massive white watch on his left wrist. Surely he's not already got a sponsorship deal on Test debut? Is he really that eager to constantly know the time? 

Anyway, enough of my frippery. Stephan Shemilt is taking over. Toodle pip.

"You have the feeling that whoever has a real bad hour in this match will lose it. That will be the difference."

Simon Mann

"It feels like there will be result in this match, unless the weather intervenes. If we're given a fair crack, someone will win this match."

A decent over from Rabada, four leg byes the only addition to the score. 

Compton and Root are looking to go quickly between the wickets here, as Root's "Yes... NO NO NO!" echoes round the Bullring.

"Every ball is a challenge. This is how I thought England might have bowled yesterday morning."

Michael Vaughan

"The sun is shining and it's all quietening down, but there's still plenty of dangerous deliveries out there."

Nick Birkett: For Compton to make his average he'll have to face another 230 balls!
