CARDIFF, July 11

Stuart Broad led England to a 169-run victory in the first Ashes Test as Australia collapsed either side of lunch on the fourth day at Cardiff's Sophia Gardens on Saturday.

Australia, well-placed at 97-1, slumped to 106-5 as four wickets fell for just nine runs in 36 balls. Chasing a record-breaking 412 for victory, Ashes-holders Australia were dismissed for 242 after tea. Fast-medium bowler Broad took 3-39 in 14 overs as England enjoyed an emphatic win in their first match under new Australian coach Trevor Bayliss.

As if defeat wasn't bad enough for Australia, Mitchell Starc -- who took five wickets in England's first innings -- was struggling to be fit in time for Thursday's second Test at Lord's after injuring his ankle. No side have made more in the fourth innings to win an Ashes Test than Australia's 404-3 at Headingley back in 1948 when Arthur Morris scored 182 and Donald Bradman, widely regarded as cricket's greatest batsman, an unbeaten 173. But Australia were well-placed at 97-1 when they lost David Warner lbw for 52 to Moeen Ali on the stroke of lunch.

Broad had bowled superbly in an opening spell of 1-10 in six overs and probably deserved more than the wicket of Chris Rogers. But, Broad -- renowned for striking in bursts -- took 2-5 in 13 balls shortly after lunch to capture the prize wickets of Steven Smith and Michael Clarke. Broad was on target in the first full over after lunch when he seemed the ball away from Smith who edged a comfortable catch to Ian Bell at second slip as, for the second time this Test, he fell for 33.

Clarke having featured in all three subsequent losing tours, then went for just four when, reaching for a drive, he guided Broad to Ben Stokes at backward point. And 106-4 became 106-5 when Adam Voges (one) edged Mark Wood through to wicket-keeper Jos Buttler.

England captain Alastair Cook has often been criticised for being excessively cautious in the field. But that this was a day when everything seemed to go right for Cook, England's skipper when they were whitewashed 5-0 in Australia in 2013/14, was exemplified by the departure of Brad Haddin for seven. Not only did Cook recall Ali into the attack, he also clung on one-handed at the second attempt at short mid-wicket to a stunning catch off a full-blooded slog-sweep against the spinner by Haddin.

Ali's first two overs Saturday had cost 22 runs but his next two had yielded two wickets for no runs, with wicket-keeper Haddin's exit leaving Australia 122-6. Shane Watson hung around for over an hour making 19 before he was lbw to Wood having, with equal inevitability, failed in a review of the decision. It was the second time this match the under-pressure all-rounder had fallen leg before and the 29th occasion in his Test career.

No 8 Mitchell Johnson held England up with a 77 that included a straight six off part-time spinner Joe Root. But Root, whose 134 was central to England's first innings 430 after they had slumped to 43-3, had his revenge when Johnson edged him to Adam Lyth at slip. Root ended the match when he caught Josh Hazlewood at long-off from bowling of Ali.
