Australia attained five-wicket win over Sri Lankain the fifth one-day international at Pallekele (Sri Lanka) and took the series by 4-1.
Australia, who took an unassailable 3-1 lead in Dambulla, rode on a record 132-run partnership between Warner and George Bailey (44) to chase down 196 in 43 overs.
Earlier pace spearhead Mitchell Starc led the visiting attack with three wickets to bowl out Sri Lanka, who elected to bat first, for a modest 195 in 40.2 overs.
But it was Warner’s 106, which came off 126 balls with the help of nine boundaries, that thwarted the Sri Lankan attack.
