West Indies were all out for 104 in the final ODI against India on Thursday.
Captain Jason Holder top scored for the visitors with 25 as their innings lasted only 31.5 overs.
Left-arm spinner Ravindra Jadeja took four wickets for 34 runs while Khaleel Ahmed and Jasprit Bumrah took two wickets each to help India restrict West Indies.
West Indies won the toss, the first time in the series, and chose to bat, but were in trouble from the very beginning. Kieran Powell was out for a duck off the fourth ball to leave the Windies.
Shai Hope, whose performance has been lauded in the series so far, was expected to shine again, but gave India its next wicket in the second over.
Marlon Samuels led a brief revival, but fell in the 11 over off a Jadeja delivery and caught by India skipper Virat Kohli. Shimron Hetmyer and captain Holder, who could have held the fort for the West Indies, soon fell as their batting order crumbled and wickets fell in quick succession.
