Sri Lanka trounced Pakistan by seven wickets in the final one-dayer in Dambulla on Saturday to clinch the series 2-1. An hour-long rain interruption after Pakistan had slumped to 81-8 in the 26th over of the first session forced the umpires to reduce the game to 48-overs-a-side. The hosts bowled Pakistan out for 102 and then surpassed the Duckworth-Lewis target of 101 in the 19th over of a one-sided game.It was Pakistan's lowest one-day total on Sri Lankan soil.
