[Scorecard: Eng Vs Aus, fifth ODI]
Ravi Bopara was the star for the hosts as his unbeaten 52 gave England victory in a match reduced to 32 overs per side due to rain. Bopara had earlier taken two wickets for eight runs in four overs.
It was a complete domination by the hosts in the five-match series. The third ODI was washed out due to rain.
England captain Alastair Cook won the toss and asked Australia to bat in wet conditions. They were off to a sedate start before opener David Warner (32) fell in the 11th over with the score on 43. Soon, Peter Forrest was back in the pavilion after making three.
There was a middle order collapse as Australia were left struggling at 55/4 in 15.4 overs. Towards the final overs, it was left to Australia's Twenty20 captain George Bailey to inject some life into the innings. His 46 not out off 41 balls with three fours and two sixes carried Australia to 145/7 in 32 overs.
In the chase, England were set a revised target of 138 from 29 overs. They had an early setback when opener Ian Bell was dismissed by Clint McKay for just four runs. England were 5/1 at the end of the first over.
Jonathan Trott too did not last long as the score became 34/2. It was left to Cook and Bopara to put the chase back on track with a 92-run partnership for the third wicket. Cook departed for 58 with his team needing just 12.
Bopara sealed the victory in the company of Eoin Morgan. Bopara was adjudged Man-of-the-match for his fine all-round show.
"I think the pitch got better as the night went on. The knock at the Oval stood me in good stead for the rest of the series," said Bopara.
Losing skipper Michael Clarke said, "Once again England showed what a class side they are. It's another reminder of what a good team they are and how well prepared we're going to have to be in 12 months time for the Ashes."
