Colombo: Tillakaratne Dilshan scored a brilliant half-century as Sri Lanka claimed a one-wicket Duckworth-Lewis win over West Indies in the rain-interrupted opening ODI of the three-match series here on Sunday.

Opting to bat first, West Indies scored 159 for the loss of eight wickets in their 26 overs, thanks to Andre Russell's 41 off 24 balls knock and Jason Holder's 36 off 13 ball innings.
