South Africa have already won the Test series against Pakistan, and will now be looking to convert that victory into a whitewash by winning the third and final Test in Centurion, starting on Friday.

The Proteas have won their past six Test series, and their most recent, against New Zealand, was a two-nil affair, so they are high on confidence and guaranteed of the top Test ranking come 1 April.

The visitors have improved as the series has progressed, from a drubbing in the opening game to a much closer effort in Cape Town. But even though the Proteas were pushed a little further, and needed some sterling efforts from players like Robin Peterson and Vernon Philander to save some sessions, they still wrapped up the game with a day to spare.

As far as team news goes, Morne Morkel has been ruled out with a hamstring injury, meaning Rory Kleinveldt will once again make a substitute appearance. After a shaky start in Australia, he recovered well in his next two Tests, and should provide able back-up to Dale Steyn and Vernon Philander.

The Pakistanis are unlikely to make changes, according to skipper Misbah-ul-Haq, who said on Thursday: "I think we need to play our best side; every game is important at Test level. We still have to have our selection meeting but I don't think too much will change (from Cape Town)."

Mohammad Irfan made his debut at Newlands, and while he was decent for the most part, he wasn't the threat he was made out to be. He also had numerous issues with no-balls, and will need to be sure to avoid that at Centurion.

Saeed Ajmal, on the other hand, was potent at Newlands and took 10 wickets in the match, and will have been gutted at not receiving support from the other end. He outclassed the Proteas top order, and they will need to review their supposed 'plan of attack' against him as it was vastly flawed.

Key Men
The South Africans will look to Hashim Amla as the key batsman here, as he averages over 80 at this ground. In eight innings, he has three centuries and three fifties, so he doesn't like to fail at Supersport Park.

Pakistan will once again look to Saeed Ajmal for their wickets, and given how he romped through the line-up in Cape Town, that will be a fair assumption. It's a pace-friendly track though, so he'll have his work cut out.
