Four batsmen posted a half-century as New Zealand overhauled the West Indies aggregate 301-8 to win the decisive one-day international by five wickets.
The win was historic for the Blackcaps, whose victory in Barbados on Monday gave them a 2-1 series win and their first ODI series victory in the Caribbean.
Tom Latham scored 69 and hit 120 in the fourth wicket while Daryl Mitchell (63) ran a chase in a stand to give New Zealand Saw victory.
Martin Guptill (57) and Devon Conway (56) combined earlier to add 82 runs for the second wicket, giving New Zealand a platform for a demanding chase.
Mitchell went out with 248 in the 42nd, Latham with 259 in the 44th, and New Zealand still needed 43. Jimmy Neesham solved it with a decisive inning of 34 innings from 11 pitches and 18 innings of Yannic Cariah’s 45th.
Neesham struck six from the bowling of West Indies captain Nicholas Pooran to end the chase with 17 balls remaining.
“It’s obviously good to contribute,” Latham said. “I think the partnership that Daryl and I were able to build put them under pressure. We set a goal of being 40-plus and we needed a ball.”
Latham appeared to have made a mistake in choosing to bowl first, as the West Indies flourished in good batting conditions.
Kyle Meyers scored 105 in 173 opening pairings with Shai Hope and Pooran hit 91 sixes for the West Indies.
The course proved better for batting than West Indies won the first by five wickets and New Zealand won the second by 50. The highest total in the series was New Zealand’s 212 in Game 2.
Meyers and Hope spent nearly 35 games together to shape the West Indies.
Their partnership ended when Hope went out at 51, and as often happens with big partnerships, partner Meyers was out after two goals and the total didn’t increase. Brandon King soon lost an aggregate score of 181-3 and the West Indies suddenly reversed.
But Pooran picked up the pace again, posting a half-century from 33 balls. When he was out in the 49th, he hit nine sixes and four fours from 55 balls.
Meyers and Hope got off to a cautious start as they found the rhythm of the new pitch, climbing to 24 points after 10 rounds and a brief rain-stop negotiation in the seventh.
“I took my time in the power game and it gave me the opportunity to get in. The last two games I quit in the power game,” Meyers said in a TV interview. “It’s not every day you do 20 powerplays, but it works out well in the end.”
