The 30-year-old Jayasuriya smashed 88 runs off just 80 balls in a rollicking 128-run opening stand with in-form Romesh Kaluwitharana (44 not out) as Sri Lanka coasted to 146 for one in 28 overs after bundling out Windies for 145 in 49.3 overs at the Sharjah Stadium.

Jayasuriya exploded in one over by fast bowler Mervyn Dillon when he pulled two sixes and a four in between for 14 runs as he raced to his 32nd one-day fifty off 48 balls, studded with five fours and three sixes. Jayasuriya also crossed 5000 runs in his 191st ODI.

The first victory in three matches gave Sri Lanka three points to level with Pakistan whom they meet in their final league tie tomorrow.
