ICC Champions Trophy, Group A
NZ 347-4 (50 overs) beat USA 137 all out (42.4 overs) by 210 runs.
New Zealand began their ICC Champions Trophy campaign with a comfortable 210-run win over the USA at The Oval.
The Black Caps scored a mammoth 347-4 thanks to a superb 145 from Nathan Astle and half centuries by Scott Styris and Craig McMillan.
McMillan, who smashed seven sixes on his way to making 64, and Astle scored 122 runs from the last six overs.
Jacob Oram starred with the ball, taking 5-36, as USA were bowled out for just 137 in the 43rd over.
The USA stunned a sparse crowd by grabbing two shock early wickets after skipper Richard Staple won the toss and put New Zealand in.
First to fall was captain Stephen Fleming who was caught by Leon Romero for 15 off veteran Tony Reid
He was soon followed by Hamish Marshall who gave a catch to Jignesh Desai, with Romero this time the successful bowler.
Any thoughts of an amazing upsety were soon banished when Scott Styris joined Astle at the crease.
The pair were initially content with ones and twos but then raised the pace by punishing any loose deliveries that came their way.
Styris fell for 75 having compiled after a 166-run partnership and although big-hitting Chris Cairns came and went in a flash, falling to Staple for three, McMillan proved a more than able replacement.
For New Zealand it was now ' happy hour' and he and Astle launched a two-man blitz on the underdogs.
It was a unique experience for the American fans
The pair's 136-run partnership was littered with sixes and fours, with McMillan taking centre stage, making his 64 from just 28 deliveries.
New Zealand's final total of 347 was just two runs short of their best-ever one-day total, set against India in 1999.
The USA began their reply in promising fashion, helped by a flurry of wides by Daryl Tuffey.
After an opening stand of 52, Mark Johnson was caught by keeper Brendon McCullum for 20 off Oram in the 10th over.
Oram removed Romero and Steve Massiah for ducks in the same over and Cairns then trapped Staple lbw with the first ball of the next.
Rohan Alexander became Oram's fourth victim for 27 and thereafter the only serious resistance came from former West Indies Test batsman Clayton Lambert.
His innings was a mix of careful defence and an occasional powerful blow, including a six over mid-wicket.
But he finally perished on the square leg boundary for 39 in a spell of 3-14 by left-arm spinner Daniel Vettori .
There were ironic cheers as Rashid Zia opened his account with a boundary after 32 balls on nought and he added another off Oram which proved to be the final scoring stroke of the game.
A third rush of blood resulted in a top edge which Cairns took safely to give Oram figures of 5-36, his best in a one-day international.
