England's new era began in sparkling fashion with an emphatic record-laden victory over New Zealand at Edgbaston.
Jos Buttler (129) and Joe Root (104) both hit centuries amid an England innings of 408 for 9, their highest ever in one-day international cricket.
Buttler and Adil Rashid (69) put on a record stand of 177 to pile the pressure on New Zealand, who were powerless to prevent England amass a stunning total.
In response, New Zealand provided a brief early threat after losing captain Brendan McCullum in the first over, but Steven Finn and Rashid both took four wickets each as the World Cup finalists were dismissed for just 198, a record 210 runs adrift of parity.
Though not yet under the tutelage of new coach Trevor Bayliss, England produced a brand of cricket in stark contrast to their performances in the World Cup against high-calibre opponents to take a 1-0 lead in the five match series.
"The guys were outstanding today and considering what we asked the guys to do two days ago we have certainly started well," said captain Eoin Morgan.
"I'm surprised it's happened so quickly but given that we have two or three new faces I thought we were brilliant. Joe was brilliant and then Jos was unbelievable. The closer we can get to this performance today on a regular basis now, the better we become."
Kiwis skipper McCullum, who won the toss and inserted England in Birmingham said: "It was good after the first ball [when Jason Roy was out] but then there were two outstanding performances so credit to England they blew us off the park.
"I probably got it wrong at the toss, it didn't swing and the ball held up a bit in the second innings but don't take anything away from England it was a complete performance.
"We did really way to get back in the game taking wickets, at 200 for 6 and we felt like we could chase 250-300 but that seventh wicket played with no fear and it's tough when guys get in like that and we need to get better with the ball and stronger in our plans.
"We knew England would play positively but didn't expect 400! They just kept coming at us. We knew we had to hold firm and keep taking wickets but the game just got away from us. Tim Southee should be fine for the next match, he came up a bit sore after the Tests."
