Nottingham - England captain Eoin Morgan won the toss and elected to field against Sri Lanka in the first one-day international at Trent Bridge on Tuesday.
England included two wicket-keeper batsmen in Jonny Bairstow and Jos Buttler, with Buttler set to take the gloves.
Bairstow was recalled to the one-day squad after a superb return of 387 runs, including two hundreds, at an average of 129 during England's preceding 2-0 Test series win over Sri Lanka.
Fast bowler Steven Finn, once second in the global ODI bowling rankings, was left out as England opted to play two spinners in Moeen Ali (off-breaks) and Adil Rashid (leg-breaks).
England's team contained five players from county champions Yorkshire -- Joe Root, Bairstow, all-rounder David Willey, Rashid and fast bowler Liam Plunkett.
Sri Lanka made one change from the side that beat Ireland by 136 runs to complete a 2-0 ODI series win in Malahide last weekend, a match in which opener Kusal Perera scored 135.
Nuwan Pradeep replaced Shaminda Eranga after his fellow seamer, suffering with an irregular heartbeat, was banned by the International Cricket Council for having an illegal bowling action.
