GALLE, Sri Lanka (AFP) — Nuwan Kulasekara and Suraj Randiv combined to vanquish Pakistan as Sri Lanka won the first Test by a massive 209 runs yesterday, their biggest win over their Asian rivals.

The tourists, set a near impossible victory target of 510, were bowled out for 300 just before stumps on the fourth day despite defiant batting from Younis Khan and Asad Shafiq.

The pair kept the Sri Lankan attack at bay for three hours to add 151 for the fifth wicket, Younis making 87 and Shafiq 80, before both fell on either side of the tea interval.

Off-spinner Randiv and seamer Kulasekara grabbed three wickets each to ensure Sri Lanka ended the match with a day to spare after Pakistan appeared to be taking the fight into the final day.

Randiv finished with seven wickets in the game, but it was teammate Kumar Sangakkara who was named man-of-the-match for his unbeaten 199 in Sri Lanka's first innings.

"It's nice to continue the winning momentum," said Sri Lankan captain Mahela Jayawardene, whose team won the preceding one-dayers 3-1 and now leads 1-0 in the three-Test series.

Jayawardene defended his decision not to enforce the follow-on despite a lead of 372 runs after Sri Lanka shot out Pakistan for a modest 100 in the first innings.
