Earlier, England captain Paul Collingwood won the toss and elected to field against Pakistan in the teams' opening Super Eights match in the World Twenty20 at the Kensington Oval.
England were unchanged from the side that played in the no result washout against Ireland in Guyana on Tuesday.
But Pakistan made one change to the team that lost by 34 runs to Australia in St Lucia on May 2, with Mohammad Asif replacing fellow fast bowler Mohammad Sami.
