England eves clinched the series 1-0 after the first ODI was abandoned due to rain.
The hosts, riding on the superb bowling effort from a disciplined attack led by Guha and ably supported by Brunt, Shaw, Colvin and Laura Marsh, bowled out Windies cheaply 41 in just 28.2 overs. And hunted down the measly target in 7.5 overs, thanks largely to Sarah Taylor's 29-ball 30 inclusive of five hits to the fence and one over it.
Earlier in the day, the 23-year-old Guha ran thro the Windies top-order plucking the first four wickets in her fiery first spell. She started the rot in her first over and second of the innings by inducing opener Stafanie Taylor to edge behind where wicketkeeper
Taylor smartly gobbled the offer. And then sent Deandra Dottin back in the similer fashion.
Two overs later Guha accounted for the scalps of Saca King and Nero to leave Windies in disarray at 12/4. Windies lost one more wicket in the shape of NAJ George but this time the benficiary was Guha's new-ball partner Brunt who bowled a probing spell of 6-4-6-1.
Guha completed her second one-day five-for with a fullish delivery which left Chedean Nation's stumps in a mess.
Left-arm spinner Holly Colvin too joined the party, taking 2/7 from six overs, while Nicola Shaw and Laura Marsh claimed a wicket apiece.
Taylor and Rainford-Brent had little trouble as they coasted to the victory target in less than eight overs.
Windies 41 all out in 28.2 overs (Isa Guha 5/14, Colvin 2/7, Brunt 1/6, Laura Marsh 1/0) lost to England 42/0 in 7.5 overs (Sarah Taylor 30 n o).
