Playing in front of a vocal and supportive crowd at Warner Park, Windies Women reached 181 for seven to win by three wickets with four balls remaining.
Earlier in the day, the hosts had restricted the visitors to 180 for seven off their 50 overs.
The victory sparked celebration in the Windies’ dressing room, as the team came from a game down to win the ODI series 2-1.
The star of the day for Windies Women was Deandra Dottin. She hit a blistering 63 to take the Player-of-the-Match award.
The powerful allrounder smashed six fours and one six, increasing the tempo at a crucial stage in the innings. She added 80 for the fourth wicket with Windies Women’s captain Merissa Aguilleira, who once again held a calm head under pressure.
Speaking after the match, Dottin was full of praise for her teammates and support staff.
“The team spirit is amazing,” she said. “Even when the heat is on, we never panic, we never stress.
“When I went in we were under a bit of pressure . . . There was a lot of tension out there as we had to win the match to win the series. We didn’t want India to get this one. We had to do all we could to pull this one off.
Dottin added: “I promised the others that I would ‘go for it’. Merissa played really well and when we were together at the crease, we kept talking and started to count down the target in fives. We wanted to be there until the end.
“We both got out, but we never lost hope. We are a strong team and we knew the others coming after us would take care of this for us.”
The victory concluded a satisfactory home series for Windies Women. Last week, they also won the Twenty20 International series 3-2.
