Kaneria struck two big blows by removing Smith and Kallis

Pakistan took the honours on day one of the second and final Test in Lahore by reducing South Africa to 259-6.

All the tourists got starts on a good batting pitch and they were going well when skipper Graeme Smith (46) and in-form Jacques Kallis (59) added 53.

But Danish Kaneria removed both before Ashwell Prince (63) and AB de Villiers (45) stabilised the innings again.

Prince was bowled by slow left-armer Abdur Rehman and De Villiers was run out before bad light ended play early.

They went into the game leading 1-0 and needing to avoid defeat to clinch their first subcontinent series win outside Bangladesh since 2000.

Pakistan, who were comfortably beaten in Karachi, brought in prolific batsman Mohammad Yousuf and former skipper Inzamam-ul-Haq, who will retire from international cricket after the game.

But after Smith won the toss, it was South Africa who were in early difficulties as Herschelle Gibbs sliced Umar Gul to gully for 13 and Mohammad Asif bowled Hashim Amla playing no stroke for 10 to make it 47-2.

Asif deserved more for an impressive first spell in which he found plenty off movement off a bouncy pitch to beat the other batsmen several times.

However, Smith dug in and Kallis, who scored 155 and 100 not out in South Africa's 160-run victory in the first Test, was assured as they rebuilt before lunch.

Leg-spinner Kaneria denied the batsmen time and room to score freely and was rewarded when he tossed one up and got it to turn out of the rough to bowl Smith between bat and pad.

He struck an even bigger blow with the first ball of the final over before tea by flighting a googly which Kallis played across the line to.

Prince was a figure of watchfulness for 132 balls, hitting only five fours in that time as he looked to re-establish the visitors.

He was beaten by Rehman's flight and sharp turn after putting on 83 with de Villiers, who was caught out of his crease as a drive by Mark Boucher was deflected by Asif on to the stumps.

Afterwards, Prince said the late blows had given Pakistan an edge and he praised Kaneria for his marathon stint of 27 overs, which began as early as the day's 12th over.

"My shot was a bit irresponsible," Prince said. "But the last wicket was unfortunate, it probably tilted the balance a little bit in Pakistan's favour.
