Asad, Sarfraz put Pak in driver's seat against Sri Lanka

Asad Shafiq and Sarfraz Ahmed exposed Sri Lanka's bowling frailties on Saturday as Pakistan took a 117-run lead and then removed two wickets at stumps on fourth day to put the hosts in a critical situation at Galle.

Resuming at an overnight score of 118-5, Asad and Sarfraz produced a spirited fightback as they rescued their team from a precarious position by putting together a 139-run stand for the sixth wicket.

While Asad displayed a flawless defence tactics by scoring his seventh Test century (131), Sarfraz smacked a quick-fire 96 to accelerate their innings.

Subsequently, tail-ender Zulfiqar Babar frustrated unimaginative Sri Lankan bowling by adding 56. Yasir Shah and Wahab Riaz contributed 23 and 14 runs respectively to put their team in a respectable position.

Off-spinner Dilruwan Perara remained the only silver lining for Sri Lanka as he scalped four wickets.

In reply, Sri Lanka lost first-innings centurion Kaushal Silva cheaply for five runs as he edged to third slip off Riaz's express delivery.

Yasir then dismissed veteran batsman Kumar Sangakkara for 18 before the end of day's play at 63-2, while still trailing 54 runs.

Dimuth Karunaratne (36 not out) and Perara (0) were on the crease and would be faced with an uphill task to get through the final day safely.
