Spinner Dunith Wellalage took 5-27 as Sri Lanka clinched a first ODI series victory over India in 27 years with a 110-run thrashing of the tourists in the third match on Wednesday. Chasing 249 for victory, number one-ranked India suffered a third successive batting collapse in the three-match series to be bowled out for 138 in 26.1 overs at Colombo's R. Premadasa Stadium. Sri Lanka, who last registered a bi-lateral series triumph over India in the 50-over format in 1997, won the series 2-0 after the opener ended in a tie.
