Record-breaking Smith knock sets up Australia triumph

Updated: 

Steve Smith's record-breaking 164 set Australia on their way to a 68-run victory in the first one-day international with New Zealand.

The captain's stunning 157-ball knock set the highest score in an ODI at the Sydney Cricket Ground as the hosts comfortably defended 324-8 and laid the ghosts of their 50-over series whitewash against South Africa to rest.

Smith also took two catches - including a stunning diving one-hander to account for BJ Watling (6) - to lead by example at the start of the three-match contest.

New Zealand's response was anchored by Martin Guptill's entertaining 114, which featured six sixes, but there was scant support down the order as their chase came up short.

And yet the Black Caps started on the front foot, claiming a wicket in the first over as Aaron Finch (0) inside-edged Matt Henry's delivery onto the stumps.

David Warner (24) looked to be well set before also chopping on as Lockie Ferguson (1-73) claimed his first international wicket.

But Smith proved far more resilient and he repelled the visiting attack to all corners of the ground, racking up 14 fours and four sixes.

By the time he skied a Trent Boult (2-51) delivery to Colin Munro, Australia were past the 300-mark and in excellent shape.

Tom Latham's dismissal off the bowling of Josh Hazlewood (3-49) for two represented an inauspicious start to New Zealand's response, but fellow opener Guptill provided some fireworks.

He raced to an 11th ODI century from 102 balls, becoming just the fifth Kiwi - and the fastest - to pass 5,000 ODI runs in the process, but Munro's 49 and a brisk 34 from James Neesham was about all the help he got.

Munro's innings involved two different bats, having broken the first when playing to the returning Pat Cummins, back on the international scene after 15 months out through injury.

The man who ended Guptill's fun with a straightforward catch was substitute fielder Glenn Maxwell, who was a notable omission following his public criticism of team-mate Matthew Wade.

The match was wrapped up in the 45th over when Ferguson (0) was the last man out to Mitchell Marsh.
