Jonny Bairstow struck a 93-ball 128 and had a 176-run partnership for the first wicket with Jason Roy (76), providing the platform for a comfortable six-wicket win in Bristol as England reached 359-4 for its second-highest run chase.
Joe Root (43 off 36 balls), Ben Stokes (37 off 38 balls) and Moeen Ali (46 not out off 36 balls) also chipped in with impressive knocks for England, which hit 16 sixes in total. The English, who host the World Cup starting May 30, rested Jos Buttler and Adil Rashid, while paceman Jofra Archer — looking to stake a claim for a place in the World Cup squad — didn't start for the second straight game.
Pakistan, which lost the second ODI by 12 runs after the first match was rained off, made 358-9 mainly thanks to Imam-ul-Haq's 151 off 131 balls. Asif Ali (51) was the other player to make a half-century.
