A loose one from Matt Renshaw is punished by Ryan Rickelton.

A full toss, Rickelton sends it back where it come from for a straight four.

Not too many of those on display today.

Just one run comes off Josh Hazlewood's latest over as the duo of Ryan Rickelton and Marco Jansen remain firm.

Matt Renshaw is now joining the attack for the first time today as Australia look ahead to the new ball being available in nine overs.

Six runs from the over for South Africa, who are close to reaching the 300-mark. At 203-1, that was to be expected.

At 232-6, 300 felt a long way away.

Four for the extras column.

Cooper Connolly pitches one up. Ryan Rickleton leaves it and as it pitches, it does not get up at all.

Passing through the legs of wicketkeeper Alex Carey, it trickles away for another boundary.

Marco Jansen sneaks a quick single off the final ball of that Josh Hazlewood over, which goes for nine.

This is proving to be quite the fruitful partnership.

Cooper Connolly, who picked up his first Test wicket earlier today, is back into the attack as Nathan Lyon takes a break.

Three balls later, Marco Jansen produces a near-identical shot with the same result.

He moves to 30 and this partnership passes the 50 mark.

The kind of shot that makes any cricket fan stop and admire such beauty. A touch short and wide from Josh Hazlewood, Marco Jansen uses his stature to his advantage to pummel the ball through the off-side.

A joy to watch as this partnership nears 50.

This feels like a really important partnership at present between Ryan Rickelton and Marco Jansen.

The kind that can make or break an innings, especially given South Africa's afternoon.

At 276-6, they've built something that stopped the flurry wickets and got the score back in the right direction.

Rickelton cuts the returning Josh Hazlewood for four now as the skies get darker. This, as the bowlers tire, is the moment South Africa have to wrestle back the advantage they built earlier in the day.

That's drinks. There's an hour and 15 minutes to go in the day.

Ryan Rickelton is just starting to get going now. He's dug in and now flicks Nathan Lyon through mid-wicket for four.

A Marco Jansen pull shot wakes Newlands from its afternoon snooze. With Jansen being so tall it's hard for bowler Pat Cummins to get the ball high enough to trouble him. It makes this an easier slap than those that caused his team-mates problems earlier. Jansen whacks it well in front of square.

Perhaps with the memory of the previous review still fresh, Australia turn down the chance to send another lbw shout for Nathan Lyon against Ryan Rickelton upstairs. It's the right decision but Lyon is causing problems.

Floodlights on. Pat Cummins running in. Was this his plan all along?

Not out. Richard Kettleborough's hearing is still good in his 100th Test. He heard that inside edge from Ryan Rickelton.

Nathan Lyon fancies another. It was a confident appeal but now Australia seem not so sure.

I always enjoy hearing what the cricket is distracting you from.

Ryan Rickelton may prefer the audits right now because he's just taken a nasty blow on the fingers from Mitchell Starc.

Nailed for four by Marco Jansen.

This could be fun.

Ryan Rickelton wisely leaves the bouncers alone during this over. There must be some on the dressing room wondering why they didn't do similar.

Mitchell Starc is going to continue with the same attack next.
