Roy and Buttler power England to 3-0 series win
Jason Roy hammered 101 off 86 balls and stand-in skipper Jos Buttler blasted 86 off 64 to help England clinch a comfortable eight-wicket victory over the Netherlands and seal an emphatic 3-0 one-day international series win.
Buttler deputised for injured captain Eoin Morgan, who was suffering with a groin injury, and saw the Dutch dismissed for 244 as Scott Edwards (64) top scored.
David Willey finished the pick of the attack with 4-36 before England made light work of the total in 30.1 overs as Buttler and Roy guided them home with unbeaten knocks.
This was the ninth time Buttler has skippered England in ODIs and his record reads won six, lost three.
Morgan's enforced absence meant he was denied the chance to atone for two consecutive ducks in the first and second matches in Amstelveen because of injury.
It will inevitably raise question marks about whether, at 35 and with his form and fitness seemingly deserting him, he will continue as England captain.
His future in the side may be in doubt but the team Morgan built in his image continued their buccaneering approach to comfortably dispose of a Dutch side ranked 14th in the world.
Buttler's innings was not quite as breathtaking as his incredible 162 off 70 balls in the first ODI, but it was chanceless as he and Roy took England home relatively serenely.
The win gave England 10 points in the ICC Cricket World Cup Super League and saw them leapfrog Bangladesh into top spot in the competition, which determines qualification for the tournament in India in 16 months' time.
