That's a shot from Sarel Erwee, driving handsomely through the covers, but some terrific scampering by Jack Leach stops the ball just short of the boundary rope.

Anderson ends the over with a beauty that just zips past the outside edge of Erwee's bat.

It will, unsurprisingly, be James Anderson to share opening bowling duties this morning.

A fine day for it...

Jonny Bairstow is straight into the action, shaping to hammer the ball back in at the stumps despite the fact Sarel Erwee hasn't moved a muscle.

That's an absolute gift, though, from Joe Root, a half-volley that Erwee merrily cracks through the covers for four.

It's not a bad ploy by Ben Stokes. Opening batsmen aren't necessarily the best players of spin and they will have been in the mindset to face pace first up.

Sarel Erwee makes an absolute hash of a sweep first up, but the ball is sliding too far down the leg side to trouble the umpire.

Joe Root will open the bowling!

It's a beautiful, warm morning here again in Manchester. England know exactly what they need to do as they head out of the dressing room.

Here come the players to the strains of Jerusalem, with James Anderson already out and bowling to Jon Lewis on the outfield.

In case you missed it, we've got highlights of all of yesterday's action - plus the Test Match Special podcast.

It takes a great all-rounder to be the star of two shows at the same time.

In the case of Ben Stokes, there was an inevitability that the day of his first century as England captain would also mark the release of his documentary Phoenix from the Ashes.

The centre of attention in two places at once.

"Who writes your scripts?" Ian Botham, one of Stokes' predecessors as an England action hero, was once asked by Graham Gooch.

Stokes doesn't follow a script. He calls the shots, not only with the way he plays, but how he is moulding the England team in his own image.

More from Stephan Shemilt on how yesterday was the Ben Stokes Show once again.

England captain Ben Stokes on TMS: "The game was massively in the balance yesterday morning but the partnership with me and Ben Foakes came as a really key time. It was really important for us to dig in and keep the scoreboard ticking over. Foakesy showed his class with the bat - we all know how good of a player he is.

"Some balls were bouncing, some were skidding and South Africa bowled really well. But I went out there with the intention to get on the front foot and score. My first hundred as captain wasn't a relief, I always feel I can contribute."

This was probably my favourite moment of yesterday...

England are quids in, strong favourites. Run scoring should be easier though once the ball gets older. It's still a very good surface.

The team are in place at Old Trafford, and you can listen using the player at the top of this page.

There's also a handy highlights show on on BBC Two from 19:00 BST tonight.

Morning!

Here's the situation - South Africa will resume very shortly on 23-0, trailing England by 241 runs after two superb centuries from the two Ben's.

The pitch is wearing and there's some turn there for the spinners but it is, crucially, a glorious day in Manchester.

Let's see which way it goes.

Yesterday was, to put it mildly, a rather good day for England.
