India had lost the second ODI in Hambantota by nine wickets but were dominant in all the other matches.
Opener Gautam Gambhir (88), Manoj Tiwary (65) and skipper Mahendra Singh Dhoni (58) scored half-centuries while Rohit Sharma (4) failed yet again. Dhoni along with Pathan (29 off 28) plundered 77 runs in just 9.5 overs before falling to Lasith Malinga in the penultimate over of India innings.
Later, the pace trio of Pathan (5/60), Ashok Dinda (2/55) and Zaheer Khan (1/53) ripped apart the Sri Lankan top-order, tilting the scale in favour of India.
Courtesy this win, India have now claimed the second spot in the ODI rankings behind Australia after starting the series in the fourth position. Both India and Australia now have 119 rating points, followed by South Africa (118).
Thirimanne shinesLahiru Thirimanne, who came to bat at number three after the fall of opener Tillakaratne Dilshan (0), was the top scorer for the hosts with his fighting 81-run knock.
Run-rate was never a problem with Sri Lanka but they struggled to keep wickets in hand as half of the batting line-up was resting in pavilion within 16 overs.
