Maia Bouchier defied injury to hit 91 as England Women outpowered New Zealand to win the fourth T20 international in Wellington by 47 runs and clinch the series.

Bouchier’s 91 off 56 balls, her second successive half-century, helped England to 177 for three, Charlie Dean taking four wickets as New Zealand were restricted to 130 for seven.

England lost Danni Wyatt, back in the side after playing in the Women’s IPL, early but Alice Capsey and Bouchier – hampered by a quad injury – added 75 in 10 overs.

Captain Heather Knight (21 not out) and Nat Sciver-Brunt (29 not out) smashed 35 off the final 14 balls to set the hosts a daunting target.

That target was made more daunting without captain Suzie Bates, injured in the field, and England struck at regular intervals.

Dean grabbed four for 26, and Brooke Holliday was at the top scoring, with 25 for the hosts.

The win gives England an unassailable 3-1 lead in the five-match series, which concludes in Wellington on Friday.

A spirited effort by West Indies saw them push England in a keen contest on Saturday night but the visitors secured a victory and with it took an unassailable lead in the five-match rubber.

England Women took a 1-0 lead over the West Indies Women following their 142-run victory in the first ODI at the Sir Vivian Richards Stadium in Antigua on Sunday.

Batting first, England was led by Natalie Sciver, who scored a game-high 90 from 96 balls, amassed 307-7 from their 50 overs. Sciver and Dani Wyatt shared in a fifth-wicket partnership of 103 in just under 17 overs that took the match beyond the reach of the West Indies Women. Wyatt contributed 68 to the mammoth total.

Tammy Beaumont (33) and Amy Jones (30) also made useful contributions.

Chinelle Henry was the best of the West Indies bowlers taking 3-59. Afy Fletcher took 2-66.

The West Indies Women were never able to cope with the demand of scoring more than six runs an over and unable to form useful partnerships, were bowled out for 165 in 40.3 overs. The exception was a 70-run second wicket partnership between Kycia Knight and Rashada Williams that produced a respectable 70 runs. Both were dismissed for 39 and 34, respectively.

Captain Hayley Matthews, who retired hurt early on, returned to score 34 for the home side.

Charlie Dean took 4-35 and Kate Cross 2-27 for the victors.

Matthews lamented her team’s inability to stick to the game plan.

"Both facets of the game (batting and bowling) we didn't do what we wanted on a decent and England was able to capitalize on it,” the captain said.

“We're going back to the drawing board and see what we can improve on in the next game. Our power play was pretty good but we let a little too many runs go by in the middle overs. It was good to see the partnership between Kycia and Rashada and I hope we can get a few more of those.”
