After England posted 191-5, rain gave West Indies an easy 60-run target.
Guyana: West Indies moved into the Super Eight stage of the World Twenty20 with a eight-wicket win via the Duckworth-Lewis Method over England in their rain affected Group D match at the National Stadium on Monday.
England must now beat Ireland on Tuesday to ensure progress in the competition and given their batting performance that should be comfortably manageable.
After England posted an impressive 191-5, West Indies got off to an electric start but rain intervened with the hosts at 30-0.
Play resumed after stoppage of more than a hour, with a revised target of 60 in six overs, a relatively easy task for the West Indies as they needed to score only a further 30 off 22 balls with all their wickets in hand.
Although they lost Chris Gayle (25 off 12) and Kieron Pollard (zero) off consecutive balls, the hosts reached their reduced target with a ball to spare. Shivnarine Chanderpaul (15 off 13) and Andre Fletcher (12 off 10) took the hosts home.
Earlier, Eoin Morgan's breezy 55 off 35 balls and a 95-run partnership with Luke Write helped England set a challenging 192-run target.
Morgan, who cracked three sixes and as many fours, teamed up with Wright (45 not out off) when England was struggling at 88 for four in 10 overs and pulled the team out of the pit.
In the 18th over off Ravi Rampaul the duo took 27 runs with the help of three sixes and a four.
Wright, who struck four sixes and one four during his 27-ball stay, gave good support to Morgan as the duo gave England a timely recovery.
Invited to bat first, England were off to a pacy start with first three overs of the match yielding 30 runs.
But they suffered the first loss soon when West Indies captain Chris Gayle removed Michael Lumb, who made 28 off 18 balls with the help of four fours, in the fourth over.
Kevin Pietersen then joined Craig Kieswetter and added 30 runs for second wicket partnership before a Nikita Miller delivery found latter's leg in front of the wickets in the seventh over.
Kieswetter had struck a huge six off the second delivery of the over but Miller took his revenge by removing the batsman in the very next ball when the Englishman was struck on the back leg.
Captain Paul Collingwood (6) was the next man to go as Darren Sammy clean bowled him in the 10th over and then the pacer struck again by removing Pietersen in the last ball of the over.
Pietersen, who made a quick 20-ball 24, had to return to the dugout after his ambitious shot found Ramnaresh Sarwan near the midwicket boundary.
The Caribbean bowlers maintained stiffling line and length as the England batsmen struggled to take big hits.
Morgan then got the company of Wright and they helped England to pile up a good total before Kieron Pollard took a diving catch off Bravo's last over to remove Morgan.
Tim Bresnan (0) remained unbeaten along with Wright.
For West Indies, Sammy took two wickets for 22 runs while Gayle, Miller and Bravo scalped one each.
