A 161-run opening partnership set England on their way to a mammoth 281-run win over Papua New Guinea in Basseterre, St Kitts and Nevis.
Ahead of an opening clash with defending champions Bangladesh, England made the most of being put into bat as George Thomas (90) and Jacob Bethell (78) built the perfect platform.
Neither man could make it to three figures, but once they had departed, skipper Tom Prest took up the charge on his way to a 77-ball 91.
Like Thomas and Bethell, he fell short of a century but a quickfire 46 not out from James Sales carried England all the way to 359 for seven in their 50 overs.
That was always going to be out of reach for PNG, with Sales building on his batting with three early wickets on his way to three for 14.
Fateh Singh then picked up two for two including top-scorer Christopher Kilapat for 19 and PNG were eventually bowled out for 78 in 27.4 overs.
