A maiden from Leach to Harmer. Stokes is going to continue. The last over before the new ball.

Just a few overs until the long-anticipated new ball for England. It has been incredible stuf from Ben Stokes, with two big scalps. They have to believe they can bowl South Africa out tonight.
It looked as though Ben Stokes was limping after finishing that over.

Stokes sets off again. England are in a good position in the game - it's just a question of when.
Harmer clips a single to finish the over.

Ben Stokes is going to keep going. When things are clicking he likes to keep going and bowl these marathon spells. And they're usually good ones. It's always tricky when you are captain to know when to stop.

Lees chases after a nice shot from Verreynne and keeps it to three runs.
Jack Leach is coming on in place of Stuart Broad.

Mark Puttick: Ben Stokes on to his 12th consecutive over. He's clearly desperate to overtake SF Barnes with whom he's tied on 189 Test wickets at the moment.

Harmer takes a quick single off Ben Stokes, who is into his 12th over.
Stokes just touched his knee as the over ends. Slight niggle?
Trail by 99
Five overs away from the new ball.
Verreynne plays a nice shot off Broad but it's chased down by Bairstow.

Where does Stokes get this energy from? It's quite remakable. He finds these balls from nowhere. England will try and get this done tonight if they can and level the series.

Stokes has just done a complete somersault and gets up quite gingerly.

There's a new ball due in six overs but England will want to get this done as soon as possible.

Solid, crab-like defence from Simon Harmer against Stuart Broad, and that'll be a maiden.

England will take the new ball when it's available but the old one seems to have been zipping through quite well for Ben Stokes...
Ben Stokes makes things happen.
He's also just accidentally walked into Ben Foakes. Happens to the best of us.

Simon Harmer ducks under a short ball from Ben Stokes, before a lovely little glide off the bat beats the close fielders and races away for four.

BBC Test Match Special statistician
Ben Stokes has two wickets in each innings plus a hundred in the match. Only one player for England has done that since Ian Botham in 1981, and that was Chris Woakes.
The last player to score a century and take five wickets in a match was Mark Butcher in 2003...
