England have beaten the edge a few times, had a couple of lbw shouts but South Africa are batting with a relative degree of security this evening. It's only a second-day pitch after all.

Into the pads from Ollie Robinson, and an obliging Dean Elgar clips it for four.

Robinson's response is another absolute beauty that just brushes past the bat. Close...

Another over ticks by, with Jack Leach hurrying his way through a maiden.

Two more left in the day. Time for a blast from Broad?

I imagine Jack Leach will have a busy day ahead of him tomorrow.

That is an absolute peach of a delivery from Ollie Robinson; quick, angled in, and somehow just rattling past the outside edge of Dean Elgar's prodding bat.

Another fine delivery from Robinson jags over the top of the stumps towards the end of the over.

Ollie Robinson will continue, with four overs left in the day's play.

Jack looks exasperated. It did all the right things. My instinct was out, but I am a former spinner!

Sarel Erwee pads up to Jack Leach's second delivery, which leads to a vociferous appeal from around the bat.

It didn't look right, and they opt against the review... ooh, and it is missing. That's a decent start for Jack Leach.

Jack Leach with the hard ball against two left-handers. The batters will be crowded you would imagine. Leach would love to nick a wicket here. Even just the one would be great from an England perspective.

Hello, here's Jack Leach.

Four overs down, five to go for South Africa's openers.

Erwee takes the tourists to double figures with a clip off his pads, it's in front of square and they get back for three.

Two more come from Robinson's last delivery, punched through a pretty much vacant off side by Elgar.

We might even see a bit of Jack Leach. He'll have an eye on popping out of those foot holes.

Another over negotiated by South Africa.

Shot!

Sarel Erwee sends a beautiful straight drive past James Anderson and into the boundary rope. It is greeted with absolute silence from the packed Old Trafford crowd.

It has indeed pitched outside leg stump.

Sarel Erwee survives - and England lose a review.

Jonathan Agnew
BBC cricket correspondent on Test Match Special

It looks like it's pitched outside.

Has it pitched outside?

Another huge review from James Anderson against Sarel Erwee.

Ooh, he wants this - and Ben Stokes obligingly sends it upstairs.

G Storey: Tricky evening session, a big lead, raucous crowd, Jimmy Anderson from the Jimmy Anderson end - it has to be doesn't it?

Peter: When was the last time that two consecutive Tests were won in three days, but by opposing teams? Just asking...

Ollie Robinson was unlucky in the first innings. He bowled beautifully and got South Africa's batters to play and miss a lot. He might fancy this.
