England face an eliminator showdown with Ireland after suffering a frustrating defeat to West Indies in their ICC World Twenty20 opener.
The host nation booked their place in the Super Eights stage courtesy of an eight-wicket win via the Duckworth-Lewis method in Guyana.
After posting 191-5 in their 20 overs, England were then left to rue a questionable revised total after heavy rainfall kept both sets of players off the pitch for some time.
Chris Gayle and Shivnarine Chanderpaul took West Indies to 30-0 before the storms, and were then asked to score another 30 runs off 22 balls upon the resumption.
And it was a task the home side completed with one ball and eight wickets to spare to the delight of their supporters.
The result will be hard to take for England who had earlier batted brilliantly to post their fifth highest Twenty20 score of all time.
Eoin Morgan impressed yet again with a swashbuckling 55 off 35 balls and his 95-run stand with Luke Wright (45 not out) gave England's innings late impetus.
New-look opening pair Michael Lumb and Craig Kieswetter exploited the early powerplay with a quickfire 34-run stand but neither pushed on from a promising start.
Lumb made 28 off 18 and Kieswetter 26 off 14, but both perished to off-spin inside the opening seven overs.
Kevin Pietersen kept the scoreboard ticking over with a brisk 24 and he could count himself unlucky with the manner of his dismissal.
After rocking back and pulling Darren Sammy for six the previous ball, Pietersen fizzed another short ball towards the midwicket fence, only for Ramnaresh Sarwan to remain motionless and take the catch.
Captain Paul Collingwood struggled for fluency, however his departure for just six paved the way for Morgan and Wright to take centre stage.
Morgan dazzled yet again with his array of deft flicks and hefty blows straight down the ground.
The exciting left-hander struck three fours and three sixes to bring up his third T20 half century in just six matches.
All-rounder Wright also found the rope with destructive effect, taking one Ravi Rampaul over for 27 in partnership with Morgan.
He finished unbeaten on 47 as England ended a couple of blows away from posting 200.
West Indies made immediate in roads into the target, Gayle and Chanderpaul both clearing the rope before rain brought the players off with the score on 30-0 off 2.2 overs.
A lengthy downpour threatened to end proceedings, however a speedy clean-up act and a quick re-calculation left the hosts with a revised total of 60 to win from six overs.
With 10 wickets remaining West Indies always looked favourites, even when Gayle (25 off 12) and Kieron Pollard departed in successive Graeme Swann deliveries.
Michael Yardy's penultimate over yielded just six, however Andre Fletcher (12 not out) booked a Super Eight spot for his team when Stuart Broad's final over cost the eight required for victory.
England face Ireland at the same venue on Tuesday in a winner-takes-all showdown.
