In a low-scoring second game in Cairns, Australia leg spinner Adam Zampa pulled up his first five-wicket haul in one-day internationals to help the hosts upset New Zealand by 113 runs and win the Chappell-Hadlee Trophy with one game remaining.
With outstanding line and length and favorable bowling conditions, the Australian attack held New Zealand batsmen in check while only defending 196, eventually skipping the visitors out for just 82 in 33 overs.
Sean Abbott, a seamer who entered the lineup after all-rounder Cameron Green was forced to withdraw owing to cramping he sustained during his game-winning performance in the first ODI, dealt New Zealand its first blow.
Aaron Finch, the captain of Australia, extended his awful streak of batting performance by being out without a run on the second delivery he faced. The first hitter has now amassed 26 runs in his previous seven innings, all in one-day internationals, during which he has helped the team to five victories and two defeats.
The only known hitter to offer some resistance was Steve Smith, who scored 61 before the Australian tailenders launched a fierce rearguard attack.
Australia, who had been reduced to 117-8 at one point, was supported by Starc, who scored an unbeaten 38, Zampa, and Josh Hazlewood by adding 78 for the last two wickets.
On Sunday, the same location will host the third and final ODI.
