South Africa are on course for an emphatic victory after Pakistan's batsmen failed to raise their game at Kingsmead.

The tourists were just 11 runs ahead with only two wickets remaining when bad light ended play 18 overs before the scheduled close.

Their top eight batsmen all reached double figures after home skipper Shaun Pollock enforced the follow-on during the morning session, but none could go on to play a major innings.

We kept up the pressure by denying them runs and we knew that when one wicket fell others would follow Mark Boucher

Yousuf Youhana's 42 was the highest score before he was removed by Nantie Hayward, who had claimed his first five-wicket haul in a Test match earlier in the day.

Pakistan began the day on 120 for eight and their hopes were pinned on Kamran Akmal and skipper Waqar Younis, with only last man Mohammad Sami still to come.

Akmal hit three fours in one over from Hayward, but the bowler gained his revenge as Shaun Pollock took a catch at mid-off to dismiss him for 12.

Waqar raced to 28 from 19 balls and the follow-on target was only eight runs away when Hayward produced a perfect yorker to wrap up the innings.

Taufiq Umar and Samil Elahi avoided unnecessary risks as they launched Pakistan's second innings with a stand of 50 in 27 overs.

Paceman Makhaya Ntini was hard to handle

Ntini broke the partnership when Elahi was squared up by a lifter and caught at slip for 18 and spinner Nicky Boje then trapped Taufiq in front for 39.

A reckless drive by Inzamam-ul-Haq (13) gave Boje his second wicket, and there was more bad news for Pakistan just before tea as a Jacques Kallis bouncer surprised Youns Khan and he was caught behind for 30.

Wickets continued to fall regularly as Hayward dismissed Youhana and Abdur Razzaq (22), while Faisal Iqbal was bowled behind his legs for 21 by Kallis after shuffling across his stumps.

Akmal was 21 not out and Waqar on two when the umpires offered the light and they retreated to the pavilion.
