Australia 497 for 8 dec (Smith 211, Broad 3-97) and 186 for 6 dec (Smith 82) beat England 301 (Burns 81, Root 71, Hazlewood 4-57) and 197 (Denly 53, Cummins 4-43) by 185 runs
Manchester: Australia retained the Ashes after beating England by 185 runs in the final session of the fourth test at Old Trafford on Sunday.
Josh Hazlewood claimed the winning wicket, trapping Craig Overton lbw, as Australia dismissed England's second innings for 197 deep into the evening session to take a 2-1 lead in the five-match series.
As the holder, Australia only needs to draw the series to keep cricket's famous urn.
Australia star batter Steve Smith was player of the match - and the major difference between the two teams - with scores of 211 and 82. Australia declared its first innings at 497-8 and its second at 186-6.
England, which scored 301 in its first innings, resumed Day 5 on 18-2, went to lunch on 87-4 and tea on 166-6.
Jack Leach, who scored a 51-ball 12, was promoted to No. 10 and batted for an hour with England fans hoping for a repeat of his third test heroics, or even bad light.
Australia held on to the Ashes in England for the first time in 18 years. It thrashed England by 251 runs in the opening test at Edgbaston, the second test at Lord's was drawn before England won at Headingley by one wicket to level the series 1-1.
Pacer Pat Cummins finished with 4-43 off 24 overs. He bowled Jason Roy (31) in the 18th over of the day, knocking over his off stump, and then claimed the key wicket of Ben Stokes, hero at Headingley with Leach.
The England allrounder got an inside edge and was well caught behind the wicket by Paine.
Stokes, who had scored just one, did not wait for a decision from the umpire and walked as Australia appealed.
That left England in deep trouble on 74-4.
Joe Denly brought up his half-century after lunch with a crisp off drive off Cummins. It was his sixth boundary and took him to 53 off 112 balls. He fell without adding further to his score when he was caught out by the bounce from a delivery from Nathan Lyon (2-51) and offered a catch to Marnus Labuschagne at short leg.
Jonny Bairstow and Jos Buttler came together and steadily took the score to 138-5 after 53 overs as Paine turned to part-time bowlers Labuschagne and Travis Head in the hope of breaking their concentration.
But it was Starc (1-46) that made the next breakthrough when he won an lbw verdict against Bairstow for 25. That left England 138-6, with Australia needing just four more wickets to retain the Ashes.
The fifth and final test in cricket's oldest regular international series starts Thursday at The Oval.
