Sri Lanka defeated the West Indies by 19 runs in the rain-curtailed third and final one-day international on Saturday to sweep the series 3-0.
Set a revised Duckworth-Lewis target of 190 runs off 36 overs, the hosts survived some anxious moments before winning the day-night game at Pallekele stadium.
The West Indies had scored 206-9 from 36 overs after being sent in to bat.
