"Rohit and Jadeja batted really well in that partnership and we should have won it easily from there," India captain Virender Sehwag said. "But it is still good to win and we hope to learn from our batting mistakes in the coming games."

The world champion Indians struggled against pace bowlers Kemar Roach (3-46) and Andre Russell (2-29).

Parthiv Patel hit a ball straight to point to be dismissed for 12 while fellow opener Gautam Gambhir edged a bouncer to be caught behind three deliveries later for 4. Roach bowled Virat Kohli for three with a ball that moved in to take his third wicket in nine deliveries.

Russell chipped in with two crucial wickets to suffocate the experienced Indian batting line-up. He bowled Sehwag (20), who hit three fours off an over from leg-spinner Anthony Martin, and had Suresh Raina (5) caught at mid-off as India slipped from 37-0 to 59-5 in little more than seven overs.

Earlier, Yadav (2-33) and Aaron (2-47) led a fine bowling display, justifying Sehwag's decision to bowl first in front of a packed stadium of 45,000.

In-form left-hander Darren Bravo top-scored for the visiting side with 60 and put on a 75-run stand for the fourth wicket with Danza Hyatt, who chipped in with 31.

No. 4 batsman Bravo, who scored two centuries in the three-test series which India won 2-0, batted himself in with singles before opening up. Off-spinner Ravichandran Ashwin dropped a return catch when the batsman was on 26.

Bravo struck six fours off 74 deliveries before he was bowled playing the wrong line to part-time spinner Suresh Raina.

Bravo and Hyatt came together when the top three were removed by the young India pace attack after initially showing promise.

Adrian Barath was the first to go, fishing outside off stump to be caught behind off Vinay Kumar for 17. Marlon Samuels was bowled off the pads by Aaron for 10, while Lendl Simmons played on off Aaron when on 19, leaving West Indies struggling at 52-3.

Following the Bravo-Hyatt partnership, the best score was No. 9 batsman Russell's 20-ball 22.

"Every time you lose it is quite disappointing," said Sammy, West Indies' captain. "Our bowlers did well to give us a start and we fought all the way to the end, but it wasn't enough."

India rested regular captain Mahendra Singh Dhoni for the series while star batsman Sachin Tendulkar was rested for the first three games. Yuvraj Singh opted out of the series due to illness, while paceman Zaheer Khan is testing his fitness in domestic cricket after havig injured an ankle and hamstring.

Praveen Kumar was withdrawn from the squad after a chest injury and subsequently ruled out for up to six weeks, including the Test series in Australia starting in December. Abhimanyu Mithun came into the squad but was not included in the playing 11.
