Lees survives again.

Oh, it's that one, is it? He didn't play it terribly well.

This is the new shot Root told me he was going to play.
Steady on, Joe! Joe Root attempts a reverse ramp shot that loops over Kyle Verreynne and England can run two.
Ugly but effective.
Lungi Ngidi is hitting a good line and length just outside Alex Lees' off stump, but Lees judges it well as he lets a couple of deliveries go.
He is less convincing with a straighter delivery to end the over but still manages to block the ball into the off side.
Lees nods in appreciation.

Alex Lees has been run out in his last two second innings, against New Zealand and India.

Sometimes as a captain, you have to think about who you would like to be facing. If you asked Joe Root, you know who he would be picking.

I can't see Maharaj bowling much longer here. Unless he gets a wicket.
Trail by 109
That's good running. Keshav Maharaj switches angle and goes around the wicket to fellow leftie Alex Lees, who clips the ball to fine leg for two.
Lees has looked more comfortable to Maharaj than he has to the seamers so far this afternoon.
Sir Alastair Cook
Former England captain on BBC Test Match Special
He's a scrapper, though, Lees. He'll keep trying to focus on the next ball.
Simon Mann

Remarkable shot from Lees, he's gone for the pull, got an under-edge and Verreynne makes a diving stop. It's been a struggle for Lees.
We need to ask Alex Lees for the lottery numbers. His luck is in - so far.
He goes for an ugly, mistimed pull and very nearly chops onto his own stumps.
A single off the last ball means he will be on strike next up too.
Sir Alastair Cook
Former England captain on BBC Test Match Special
Lees has seemed a bit more cumbersome today. That was a shorter ball and you'd expect his weight to be going back to hit it but he didn't really move at all.
Edged....but safe! Another life for Alex Lees as a thick edge off a short, wide delivery from Ngidi disappears through fourth slip for four.
Ngidi then goes full with the next delivery and Lees just about jams the bat down on it and can scamper a single.
Tense times.
Sir Alastair Cook

It was tricky conditions for batting on day one but today the new ball has done a little bit, not too much. And the two wickets for the spinner, neither of them turned much.
Four men around the bat for Alex Lees, who nudges off the back foot for a quick single.
Just the two close fielders for Joe Root, despite being fresh at the crease, and he gets off the mark with a clip to extra cover.
Root and Lees then have what looks like a serious conversation at the end of the over. There's a lot of work ahead of them if England are to get out of this predicament.
Sir Alastair Cook is correct. Keshav Maharaj will continue.

I would bowl seam but I think Dean Elgar will carry on with Maharaj.

It'll be interesting to see what South Africa do with Maharaj now Root is in. Will they take him off and bring on a pace bowler?
Lungi Ngidi opens the afternoon session at the Nursery End. Threes slips in a gully in place as South Africa sense more wickets.
Ngidi goes around the wicket to the left-handed Lees, who gets himself into a tangle and very nearly plays on, the ball instead smacking into his pads and rolling clear of danger.
Lees does get some bat on ball with the final delivery, clipping it off the pads into the leg side for a single.
