Lead by 96

Oooo this one isn't nice. Cooper Connolly has ducked into a bouncer from Marco Jansen. It has thudded right on the lid.

Nathan Lyon is taking charge of the situation and calling for the physio to help out his young team-mate.

Frustration for South Africa.

I am giving Simon Harmer the benefit of the doubt here. I don't think this has carried to him at slip off the edge of Nathan Lyon. It gets there at that awkward height that just squeezes his fingertips between ball and grass.

Ah that's glorious from Cooper Connolly. He stands up to drive through the covers for four, showing he has the shots as well as the ability to stick around.

If Steve Smith does come back for Marnus Labuschagne at number three, as Shaun Pollock suggested earlier, it would leave space for Connolly to remain in Australia's XI.

Or do they need another frontline batter? Connolly is yet to score a first-class century. I'm intrigued to know your thoughts.

Again, Nathan Lyon faces only two balls in this over from Wiaan Mulder. He sees the second off with an emphatic leave him above his head.

Newlands looks the place to be again today. There are spectators sunbathing on the grass banks.

It could be Australia's cricket smarts that win them this Test. Even 23-year-old Cooper Connolly is turning down singles to protect Nathan Lyon. He knows there is plenty of time left. South Africa's tail was blown away.

Nathan Lyon survived alongside Matt Renshaw for 190 minutes in Australia's first innings in the first Test. If he repeats that this game will be done bar the shouting.

Four byes as Wiaan Mulder fires one down the leg side frustrate the hosts further.

Cooper Connolly bats a lot like Travis Head. He plays away from his body. His feet don't move loads. But he does seem to have good enough hand-eye to cope.

WinViz update? Australia strengthened their position in the morning session despite South Africa taking those four wickets.

Marco Jansen has the ball in hand.

Here come the players for the afternoon session.

Australia's lead is 82. South Africa cannot let that grow much further.

The afternoon session will begin at 11:10 GMT so are going to pause things briefly.

Here's some reading to keep you going until then:

• What's the future hold for Marnus Labuschagne?
• Futuristic eco cricket ground in Spain eyes Test match
• Batty leaves Surrey to join Chennai Super Kings
• Ireland captain Stirling out of Namibia series

South Africa couldn't have hoped for much more - four wickets for the loss of 81 runs - but Australia are still well placed at lunch on day three. They are 411-8, with a lead of 82.

After progressing through the first 45 minutes unscathed, Josh Inglis reached his second Test century before edging Simon Harmer behind later in the same over.

Harmer also saw off Alex Carey for 80 soon after.

Kagiso Rabada also chipped in with the wicket of Pat Cummins for a duck and Gerald Coetzee nicked off Mitchell Starc for 11.

But Cooper Connolly is still there on 20 alongside Nathan Lyon, who has one to his name.

Nathan Lyon getting a bit of chirp from South Africa wicketkeeper Ryan Rickleton et al round the bat, but the Aussie spinner is chuckling away to himself so seems to be revelling in it.

Lyon stoutly sees off the final six deliveries before the interval.

Australia lead by 82 runs.

Now then, Gerald Coetzee's maiden to Cooper Connolly gives Simon Harmer a chance to bowl six balls at Nathan Lyon.

Simon Harmer is keeping the pressure on but Cooper Connolly farming the strike well to protect Nathan Lyon, the new batter.

Gerald Coetzee arrows a yorker into Cooper Connolly's off stump and he edges a drive which falls just short of the slip cordon.

Connolly manages to lean into another full delivery from the South Africa seamer later in the over and jabs it through extra cover for four.

Every run vital for Australia now.
