Australian skipper Aaron Finch just missed a record hundred while Adam Zampa took four wickets and Pat Cummins claimed three when the Aussies demolished Pakistan by 80 runs in the third ODI in Abu Dhabi on Wednesday.
Finch hit a 136-ball 90 to steer Australia to 266/6, while Zampa (4/43) and Cummins (3/24) bowled Pakistan out for 186.
The win gives Australia an unassailable 3-0 lead in the five-match series with the last two games taking place in Dubai on Friday and Sunday.
Australia won the first two matches by identical margins of eight wickets and continued their dominance of a depleted Pakistan side who rested six of their key players in a surprise move, two months before the World Cup.
Cummins proved once again that he is one to watch at the global showpiece after also taking 14 wickets in the series win in India earlier this month.
