|Fourth one-day international, Antigua:|
|West Indies 249-8 (50 overs) beat India 146 (39 overs) by 103 runs|
Anthony Martin bowled the West Indies to victory in the fourth one-day international as India collapsed.
Martin took 4-35 and Andre Russell 3-16 as India slumped from 110-4 to 146 all out in just 39 overs.
Earlier Lendl Simmons and Kieron Pollard hit half centuries in a total of 249-8 as the hosts looked to win their first game of the series.
India had already had an unassailable 3-0 lead and rested several key players as the Windies triumphed in Antigua.
Windies skipper Darren Sammy was happy with his side's response and believes they are getting better all the time.
"We did a lot more things better in this game," he said.
"Throughout this series we have been improving, and in this game, we put a decent target of 250 on the board.
"The bowlers throughout the series have been collecting wickets early, and this time we were in a similar situation, and handled it differently.
"We had a different mindset, and the guys put the ball in the right areas and got the wickets we needed to complete a victory."
Simmons hit three sixes on his way to a knock of 67 from 78 balls but the opener saw wickets tumble steadily at the other end before he was run out chasing a suicidal call for a single.
The Windies were in trouble at 103-5 but rallied to post a defendable target as Pollard hit 70 from 72 balls in a 96-run partnership for the sixth wicket with Carlton Baugh.
Baugh then turned in a lively display behind the stumps as he took three early catches as well as stumping Virat Kolhi for 22.
Rohit Sharma provided some resistance with a breezy 39 from 47 balls before his innings came to an end when he holed out to Darren Bravo off the bowling of Martin.
And the Indians then lost their last three wickets for eight runs as Martin wrapped up the tail.
Captain Suresh Raina admitted his side had batted poorly.
He said: "Our shot selection was really wrong. We lost our shape, and we did not have any partnerships."
