The equation is simple. South Africa have to take 10 wickets. Australia require 288 runs for victory. And the winner walks away with a series victory and the world No. 1 ICC Test ranking.

There is no middle ground, according to Proteas centurion Ryan Rickelton, heading into the final day of this riveting series here at Newlands.

"It's win or lose, I guess. No draw tomorrow (Saturday)," Rickelton said. "If you had told me that it's going down to the third Test, day five, with all three results on the cards, or even two results on the cards, yeah, I wouldn't have believed it.

"It's been a special series. It's ebbed and flowed properly in all three games. Both teams have edged ahead and the other one has clawed back. There have been some mistakes made and some really good things done. It's been a cracking series."

There's no doubt that this series has been one for the ages. Devoid of all the drama and controversy of the last time Australia were in South Africa eight years ago, the focus has purely been on the cricket out in the middle.

And that alone has produced enough subplots and twists and turns to put the local soapie Suidooster to shame.

The fourth day alone was drama-filled, with the Proteas almost enjoying a physical resurrection thanks to Ryan Rickelton and Wiaan Mulder's 156-run partnership for the sixth wicket, which breathed life back into the home side.

Only for Australia to pull the plug by running out Rickelton shortly after the left-hander reached his third Test century, precipitating a Proteas collapse of four wickets for just 16 runs.

But the credits could not roll just yet. South Africa still had one last scene to complete, with Mulder moving towards his milestone with last man Kagiso Rabada for company as the pair added an invaluable 36 runs for the 10th wicket.

"That was really, really big. Massive," Rickelton said of the partnership. "Obviously, it was a bit frustrating. I think we were in such a good position to push on towards 300, 350. And obviously the run-out kind of took that away from us. So that was a bit frustrating.

"But still, to be able to get effectively 290 and ask them to do it on a Day 5 wicket is big. Psychologically, it takes a lot out of you as well. So those last 20 or 30 runs they managed to compile hopefully will be enough to take us over the edge."

How does Rickelton, with the perfect vantage point of having spent all that time out in the middle and behind the stumps, see the Proteas claiming those 10 wickets, especially on a surface he admits is still "flat" and "lovely to bat on"?

"I just think with that new ball, there's obviously runs available and there are obviously wickets too," he said.

"It has been quite slow. If Australia fancy having a go at it, that might just factor into it. For them to bat at effectively three runs an over for the whole day will be a big ask, especially on a slower, lower, deteriorating wicket.

"For the right-handers, that ball is vicious going back in. So we know Australia have got four left-handers. We're obviously going to look to put them under pressure that way.

"Whether that means hanging it out there and waiting for them to come to us, or attacking guys differently according to their own style, we know we've got our work cut out for us."
