Fifteen of the 20 Pakistan wickets that fell in the first Test in Johannesburg were to catches behind the wicket or in the slips.

South Africa won by 211 runs to take a 1-0 lead in the three-match series.

"I'd like to put it down to our guys creating good angles, getting good swing," said Smith.

"For them, the bounce and the shape (means) there is a very different style of batting needed in those conditions.

Any time you have that many caught-behinds, you need to have a look at how you leave the ball."

Smith said he hoped the Pakistanis, who were bowled out for a record low 49 in the first innings at the Wanderers, would come into the second match with a tentative mindset.

"They allowed us to bowl at them. We managed to control the run rate for a large part of the game. That allowed us to attack them more. If they come into this match with a mindset to leave, they are going to be tentative.

That will allow us to create pressure on them and will play into our favour."

Pakistan coach Dav Whatmore said shot selection was the key for his team's batsmen.
