Jansen's day goes from bad to worse.
Marco Jansen looks very nervous. He starts with three dots but his shoulders are drooping. He's had a tough day.
Is it time for the Marco Jansen redemption arc?
First baller with the bat, 0-27 in his first three overs, finish it with a hat-trick?
Need 7 runs to win
Two singles end the over.
Cummins and Starc aren't taking any risks. They'll go to the 50th over if they have to.

A big expansive drive and one of those days when on another day which might have broken through.
Big swing and a miss from Pat Cummins! Where did that come from?
That is very close to off stump. Aiden Markram is on his knees in disbelief.

Gerald Coetzee needs oxygen and a wheelbarrow to take him off. He's given absolutely everything.
Need 9 runs to win
He keeps steaming in, but with no reward this time. He still has the energy to whack Mitchell Starc in the ribs, though.
The equation for Australia is very simple. It feels a lot more tense than it should be.

Gerald Coetzee loves big moments in games. So that's why he's been thrown the ball.
Blimey, Gerald Coetzee is going to continue. He's hobbling. This is a sensational effort from the young man.
Need 10 runs to win
Just two from another testing Markram over but Australia edge closer.
South Africa fans have heads in hands in the crowd. Their dreams are dwindling.
Chipped in the air... and drops short of the fielder!
Suspect we're going to be seeing plenty more of Gerald Coetzee.
Need 12 runs to win
Bowled 'im!
A bit of excitement from those who didn't realise it was a free hit, as ever.
No-ball. Free hit.
Was it one over too many for Coetzee?
Need 14 runs to win
And there goes the pressure.
Wide, and Cummins slashes it away for four.
Brief break in play as Coetzee goes down with cramp.
Hardly surprising, given this is his seventh over on the trot.
Coetzee continues and gets Cummins with a sharp bouncer that flies up off the top of the bat but lands safe! Get the fielders in!
Need 18 runs to win
And here's Pat Cummins, just effortlessly exuding calm and composure to steer Australia closer to victory in singles.
Here's Aiden Markram.
