CHENNAI: England kept their World Cup hopes alive with a dramatic 18-run  win over the West Indies in a Group B day-night match here at the MA MA  Chidambaram Stadium on Thursday Chasing 244, the West Indies  were in sight of a certain victory needing 22 runs from 52 balls. They  were 222 for six after a stand of 72 between Ramnaresh Sarwan (31) and  all-rounder Andre Russell (49) rescued them from the depths of 150 for  six.But they lost their final four wickets for three runs to  finish on 225 all out in 44.4 overs, with Sulieman Benn the last man  dismissed when he was run out by Jonathan Trott's throw to wicketkeeper  Matt Prior with more than five overs left Off-spinners James Tredwell and Graeme Swann took seven wickets between them.   England now need Bangladesh to lose to South Africa on Saturday. If Bangladesh win, England can still go through if India beat West Indies on Sunday in the final match of Group B.However, a West Indies win would see them into the last eight.Russell,  caught on 39 at long-on by Trott only to be awarded a six after the  diving fielder just glanced the boundary marker, saw his 46-ball innings  end when he was lbw to World Cup debutant Tredwell.The spinner was named man-of-the-match for his four for 48 to spark the climatic slump.England then saw Sarwan turn Swann (three for 36) straight to Ian Bell at short leg.Two balls later Kemar Roach was caught by a diving Chris Tremlett off Swann to leave West Indies 223 for nine. West Indies had seen fit-again opener Chris Gayle (43) make a typically rapid start as their fifty came up inside five overs.But  Tredwell took his first one-day international wicket when, fifth ball,  he had Gayle, pushing half-forward, lbw to end a 21-ball innings  featuring a six and eight fours. Tredwell, in only his  fourth ODI, then had Devon Smith stumped by wicketkeeper Prior as he  took two wickets for nine runs in eight balls.Tredwell then had Darren Bravo edging to England captain Andrew Strauss at first slip.Sammy struck several sixes off Tredwell before playing onto Ravi Bopara for 41 off 29 balls.And when Devon Thomas also played on to Bopara, West Indies were 118 for five.Swann had the big-hitting Kieron Pollard plumb lbw for 24, despite a desperate review, and West Indies were six down.Earlier, Luke Wright kept England's hopes alive with 44 after they'd slumped to 134 for five. Trott  (47) was the only other England batsman who made more than Strauss's 31  in an innings where debutant leg-spinner Davendra Bishoo took three  wickets and Russell claimed four.
