England 151 for 8 (Glenn 26, Taylor 2-12) beat West Indies 104 for 8 (Dottin 38, Villiers 2-10, Ecclestone 2-19, Glenn 2-24) by 47 runs
Valuable runs and crucial wickets for youngster Sarah Glenn handed England a second 47-run victory in as many contests with West Indies and a 2-0 lead in their five-match T20I series.
Having lost the toss and been sent in, England's recognised batters struggled to post a significant score among them, leaving it to Glenn - supported by the experienced Katherine Brunt - to push their side beyond 150 mark with a 46-run partnership when a significantly lower total looked likely.
Legspinner Glenn then made the breakthrough that removed a dangerous Deandra Dottin, lbw for 38 off 40 after posting 69 in a losing cause in the first of five matches, and effectively ended West Indies' hopes when she had captain Stafanie Taylor stumped on 28 thanks to wicketkeeper Amy Jones' second piece of brilliance for the evening.
All of England's youthful spinners prospered with Glenn, Sophie Ecclestone and Mady Villiers taking two wickets each.
Opportunity goes begging for Windies
West Indies had their chances in this match, but a rash of dropped catches, a failure to finish off the England tail having done the hard yards and then the inability of anyone to step up when likely stars Dottin and Taylor fell left them wanting.
At the end of the Powerplay, the tourists were in touching distance at 36 for 1, having lost Hayley Matthews - who looked to be suffering from back pain - for just 3 when Brunt got a leading edge to fly to Heather Knight. That compared with England's 44 for 1 and, with Dottin and Taylor at the crease, they can always entertain hope.
By the time Glenn struck Dottin high on the back leg, kneeling down as she shaped to sweep, West Indies had moved to 72 for 2. Offspinner Villiers had Lee-Ann Kirby stumped thanks to some swift glovework from Jones before Glenn deceived Taylor for a stumping that had the visiting captain striding off the pitch while the TV umpire was still taking a look. From there, it seemed there was simply no-one to stand up amid a stream of wickets which left West Indies well short for the second game in a row.
Seventh over and out, out
West Indies did some serious damage in an eventful seventh over bowled by Taylor.
Nat Sciver had survived two chances in the previous over. The first came as she looked to heave a Shakera Selman cutter to the leg side but chipped back to the bowler, who got her fingertips to it but shelled the return catch as she went to ground. She was then put down by Shemaine Campbelle, diving to her left behind the stumps.
Sciver's luck ran out with just eight runs to her name when Taylor pinned her back with the first two balls of her second over and then tossed one up, beating the outside edge as Sciver charged and the ball skidded on, Campbelle whipping off the bails with Sciver well out of her crease.
Knight, who was yet to score, was put down after slashing Taylor to Afy Fletcher at short third man. She was then involved in a mix-up with Danni Wyatt, who nudged Taylor into the off side and set off for an ambitious single, only to be sent back by her captain as Campbelle gathered Dottin's sharp throw from backward point and removed the bails.
Wyatt was run out for 14 and England were 43 for 3, having added just 11 runs since Tammy Beaumont, the star of England's win in the first match, was out for 21 lofting Selman to Chinelle Henry at mid-on in the fourth over. Taylor finished with 2 for 12 from her four overs after she also had Fran Wilson stumped by Campbelle for 4.
Taylor's contribution with the bat later took her past 3000 T20I runs, making her only the second woman to the landmark.
Better ending for England batting
England were teetering at 96 for 6 when they lost Jones for 25 and Knight for 17. With no-one in the top or middle order having posted an innings of real note, it fell to Brunt and Glenn to fulfil the team brief identified after the first match of finishing better.
They did so with distinction, with Glenn taking the lead in a 46-run partnership with Brunt from just 30 balls. Just-turned 21 and playing her 12th T20I, Glenn notched up 26 runs of 19 balls, including four fours before she was run out by Henry on the last ball of the innings. Brunt struck 18 off 14 before she was bowled by an excellent yorker from Selman, bringing in Ecclestone, who added nine off four balls.
Having lost five wickets and added just 31 runs in the last five overs of the first match, this time, England added 51 runs for the loss of two wickets in that time.
