Quintyne, showing maturity beyond her age, made a top score of 29, batting at number eight to lead a West Indies revival and a below-par but fighting 148 off their allotted 50 overs.
Bowling with zest and accuracy, the Barbadian all-rounder then returned to claim figures of two for nine off four overs with her sharp turning off-spin to help bowl out New Zealand in dramatic fashion for 59 off 28.5 overs.
With victory the only recourse if they were to make tomorrow’s game three of significance, West Indies won the toss and, on a surface that coach, Sherwin Campbell, said looked a good batting track, took first strike.
The decision yielded dividends in the opening stanza with openers Jamaican Natasha McLean and Barbadian Kycia Knight putting on an entertaining 52 for the opening wicket.
However, as soon as the partnership was broken when McLean was caught off the bowling of left-arm seamer Sian Ruck for 21, things went downhill for West Indies.
They lost their next seven wickets for just 43 runs, with Knight, Stafanie Taylor, Deandra Dottin, and captain Merissa Aguilleira, being among the victims.
This then brought to the crease Quintyne, who, along with returning fast bowler Shakera Selman put on 43 for the ninth wicket, which took the score from a paltry 95 for eight to a level of respectability at 139 for nine.
Quintyne hit one four. However, it was the manner of calmness and level-headedness in which she compiled her runs that drew kudos from the crowd, which, while not as big as the near-capacity North stand-only crowd on Sunday, was better than a few regional men’s games of the past.
Selman, who missed the first game after picking up a slight injury, made 22 before she was last woman out off the last delivery of the innings.
Outstanding left-arm slow bowler Morna Nielsen, who claimed the wickets of Dottin, leg before wicket; and Aguilleira, stumped; as well as Shemaine Campbelle, who scored 10, was the pick of New Zealand’s bowlers.
She ended with three for 12 off 10 overs, which also included four maidens. Leg-spinner Erin Bermingham, two for 15 off eight, and captain and pacer, Suzie Bates, two for 27 off seven, were the other leading wicket-takers.
When New Zealand batted, they were never allowed to settle, thanks to a combination of good fielding and tight bowling, especially from left-arm spinner Shanel Daley up front.
Off-spinner Taylor ended as the leading wicket-taker with three for 10 off eight overs with while Daley, two for 14 off six, being next best.
