England took their T20 success on tour in the West Indies to four from four on Sunday, winning the second-last game by 49 runs as spinner Sophie Ecclestone claimed a new women’s cricket record.
The 23-year-old has taken 56 international wickets this year, the most any woman has ever taken in a calendar year.
The tourists won the toss and chose to bat, finishing with 131 runs while the hosts were dismissed for just 82 in reply.
Ecclestone claimed two wickets off her three overs, while Charlie Dean was named player of the match for her efforts in taking two wickets on top of scoring 20 runs.
England claimed the series victory to go with their ODI sweep after defeating the West Indies by 17 runs in the third game on Saturday at Kensington Oval.
The final match of the series will be played at the same ground on Wednesday.
