South Africa head coach Ottis Gibson says he will focus of pace bowling as the main strength in his side, who saw off India at Newlands in the first Test of three.
The Proteas secured a 72-run victory over the tourists, despite losing pace spearhead Dale Steyn to a heel injury during the Indian first innings.

Duanne Olivier and Lungi Ngidi have been added as replacements for the stricken Steyn for the second Test at Centurion, with Gibson putting his faith in one of that pair to augment the existing trio of Kagiso Rabada, Morne Morkel and Vernon Philander.
With two more Tests against India and four against Australia coming up between now and the end of March, Gibson told reporters: "I'm a very fast-bowling minded coach and I guess we will always have to find a balance to see if we can get four fast bowlers in the team, first of all.
"We'll look at things like are the conditions suited to four fast bowlers. If not we try and shape the team in other ways.
"Ultimately, especially in this series and for the rest of the summer, we will be looking to see how best we can fit four fast bowlers into whatever formula we come up with.
"When you are playing at home, you must play to your strengths. We had, in this game, three guys bowling over 140 kph, so we need to use that."
South Africa are 1.44 to win the second Test against India and are 1.015 to claim a series victory over the tourists, who are 29.00 to fight back and secure a 1-1 drawn series.
