Ok, Australia. We get it. You have shown fight but let's crack on now... those 3pm kick-offs are getting closer. Maiden.

If you're watching this on the tele, just look at the energy which goes through Simon Harmer's shoulder when he releases the ball. He's giving it every chance to spin if it finds a footmark. Nathan Lyon gloves one for four to bring up the Australian 100.

Aiden Markram slides one past Pat Cummins' outside edge. The Australian captain nods in approval. Game respects game.

Hands on heads in the South Africa slip cordon as Nathan Lyon scoops four over the four waiting catchers. Australia are playing a few extra shots now. I reckon Lyon doesn't back his defence as much as Cummins.

With the clouds rolling in, I just checked the forecast. Rain won't be saving Australia. This is Cape Town, not Old Trafford.

Pat Cummins, with flashes of fluorescent yellow on his upturned collars, shovels a loosener from the returning Aiden Markram behind square for four as the clouds roll in from above Table Mountain.

Shot of the day! Nathan Lyon stands tall and punches four through the covers off Kagiso Rabada. He swivels on a short ball to turn two round the corner, then hits another two into the large gaps in the off side.

Pat Cummins is showing unbelievable restraint - he's scored just five off 65 balls. Maiden over.

My colleague, Matthew Henry, reckons he'd rather see Australia play some shots because they're not going to bat out for a draw. They probably won't, but there's more chance of that than them winning? And at least it shows they have some resolve?

In the middle, Lyon gets a streaky four through the slips. The rest of the over is a succession of plays and misses. Rabada is too good and Lyon suggests as much with an embarrassed smirk.

Simon Harmer has figures of 4-9 from his 17 overs. Australia's tail is holding him and South Africa up here though.

That's a fair point from Mike. The Aussies are putting a price on their wicket here. Cameron Green's brain fade aside, they have been very disciplined since lunch.

Oh, hello. Nathan Lyon takes on Kagiso Rabada's short ball and pulls it from in front of his eyes for four.

Simon Harmer is almost getting too much turn here. He gets one to spit off the surface but it hits Pat Cummins' thigh pad on its way through to leg slip.

A couple of balls later and an inside edge pops up but drops in front of the fielder under the helmet. Things are starting to happen again.

Australia's total is swelled by four byes but there's no runs off the bat. Incidentally, Nathan Lyon's longest batting stint is the 190 minutes he spent at the crease in the first Test for his 27 runs. He's only ever batted more than two hours on one other occasion.

Pat Cummins' clear gameplan of farming the strike and turning down singles makes Cameron Green's brain fade look even worse. Drinks.
