Lahore, Oct.11 : Pakistan put up an improved performance in its second innings in the second Test against South Africa at Lahore's Gaddaffi Stadium on Thursday, but was still 349 runs adrift of the Proteas victory target when bad light brought a premature end to the fourth day's play.

Pakistan will have to bat out the whole day on Friday to ensure a draw. At the draw of stumps, Pakistan had scored 107 for the loss of Salman Butt's wicket. Younis Khan and Kamran Akmal were unbeaten on 47 and 49 respectively.

Earlier, the South Africans amassed a huge second innings score of 305 for four before skipper Graeme Smith announced the declaration. Coupled with their first innings lead of 151 runs, the Proteas have set a daunting target of 456 runs for the Pakistan team.

The South Africans had Jacques Kallis to thank for their impregnable position in the Lahore Test. Kallis scored his third century in four innings and shared a 207-run third wicket partnership with Graeme Smith - who scored his first century in over two years.

Pakistan's depleted bowling attack suffered at the hands of both South African batsmen. With Mohammad Asif missing from the attack, it was Danish Kaneria and Abdur Rehman - backed by the legspin of Younis Khan - who shared most of the bowling. South Africa could only add 57 runs in the morning session, and it was mostly dot balls and the odd single that formed the better part of proceedings throughout the day.

Kallis was patience personified against the spinners, who managed to extract turn and bounce in batsmen-friendly conditions. Beaten on a few occasions by Rehman - even managing an inside edge onto his thighs that Kamran Akmal failed to hold on to - Kallis looked solid in defence and frustrated the home team. With the spinners unable to get the breakthrough, Shoaib Malik, the captain, decided to take the new ball.

Pakistan had a chance to snare Kallis after he mis-hit one straight down the ground but Malik failed to hold on to the catch after covering a lot of ground.

Smith, who reached his ton in the morning session, too played an innings of composure and patience. He survived a few leg-before shouts and was beaten on a few occasions by Kaneria's spin.

He was eventually dismissed trying to sweep Kaneria out of the ground for 133. His innings laid a solid foundation for his bowlers to work with to clinch a clean sweep of the series. (ANI)
