Australia 8 for 280 (Smith 94, Labuschagne 58, Marsh 50, Rashid 3-57) beat England 208 (Billings 71, Vince 60, Zampa 4-45, Starc 4-47) by 72 runs
Sydney: Steve Smith made a high-class 94 as Australia beat England by 72 runs in the second one-day international to secure a series win with a game to spare.
The former captain shared stands of 101 and 90 with Marnus Labuschagne and Mitchell Marsh, who each made half-centuries, as the hosts posted 280-8 in Sydney.
That looked a very long way off for England when Starc removed Jason Roy and Dawid Malan in the first over of the chase to leave them 0-2.
It got worse for the tourists, who chose to rest captain Jos Buttler, when Josh Hazlewood - skippering Australia for the first time with Pat Cummins also rested - bowled Phil Salt.
A 122-run partnership between James Vince and Sam Billings brought England back into contention before four wickets in three overs, including three for just one run, put the home side firmly in control.
Starc ended with figures of 4-47 and Adam Zampa took 4-45 as England were eventually bowled out for 208 in 38.4 overs and Australia take an unassailable 2-0 lead into Tuesday's third and final ODI at the Melbourne Cricket Ground.
