The Windies women have taken the momentum from their final-game win in an ODI series against South Africa in the Caribbean to win the first game of the follow-up T20 series.
The Windies, at the Kensington Oval, chose to bat, scoring 124-6 in their 20 overs before restricting the South Africans to 107-7.
There were no heroics for Hayley Matthew with the bat after her first ODI ton, on Saturday, gave the Windies a share of the series, but the team were good enough to make up for her failure at the top of the order.
Matthews, 8, and skipper Stafanie Taylor did not get the team off to the start they would have wanted.
Shemaine Campbelle, five, also made things difficult with the Windies women, teetering at 79-4 by the time she got out in the 15th over.
By that time, opener Natasha McLean had gone for a well-played 38 from 41 deliveries.
Deandra Dottin, 22 from 19, added some life to the innings
Chadean Nation, seven from six deliveries, Merissa Aguilleira 14 from 10, and Kycia Knight unbeaten on 14 from 10 as well, all helped in pushing the total toward something defendable.
The group were combatting the bowling of Saarah Smith, 2-17, Zintle Mali, 2-24, Tumi Sekhukhune, 1-12, and Marizanne Kapp, 1-25.
124 shouldn’t have been enough, except nobody told the Windies bowlers who were purposeful.
Connell started brilliantly for the Windies, removing Lizelle Lee with the score on just one after four deliveries. Lee’s opening partner, Laura Wolvaardt was next to go, this time with the score on 14 after all of 3.5 overs already gone.
To make matters worse, Taylor was getting into her bowling, the skipper eventually completing her four overs for just 16 runs, and perhaps more importantly, bagged three wickets.
Afy Fletcher was also good, ending with figures of 2-17 from her four overs, while Anisa Mohammed went wicketless, but bowled with control to limit the cost of her four to just 24 runs.
Connell ended with figures of 1-19 as only Kapp, 30 from 22, and Chloe Tryon, 23 from 16, offered any real resistance.
