England defeated Australia by three wickets
Never say never in sport but it is safe to say that no Australian side in the last dozen years has had a one-day international ripped from their clutches by an innings to match the sheer brutality of powerhouse Kevin Pietersen's 91 from 65 balls, including eight fours and four towering sixes.
It wasn't as though he rounded off a match already nearly won by other batsmen because a regular loss of wickets as England chased 253 left him almost stranded at 160 for six and 214 for seven.
The run-rate was a growing problem - 93 from 12 overs, and 76 from ten before Pietersen took over and roughed up every Australian pace bowler except the impeccable Glenn McGrath.
Mike Kasprowicz was hit for 18 in one over and Jason Gillespie for 17 in another. A fusillade of fours and sixes sent another 15,000 capacity crowd wild as the victory was clinched with 15 balls to spare.
With invaluable bit parts from Vikram Solanki and Jonathan Lewis, the sixth-wicket and seventh-wicket partnerships swallowed up those 93 runs with Pietersen scoring 70 of them.
His massive hitting meant that the last 76 runs came off 45 balls to rival anything seen on the famous Bristol ground. Significantly, for the second consecutive day, captain Ricky Ponting showed that he might be able to lead a top side in the field when all the bowlers are firing but he lost the plot when Pietersen took over.
A prime example was when Lewis was on strike at the start of the 46th over yet Ponting unaccountably had only four men in the circle when he should have had a couple more to prevent the easy single which was taken to put Pietersen on strike. The next two balls went for ten when the batsman should have been at the other end.
Add his first-ball duck to put Steve Harmison on a hattrick and the tourists' captain is under greater pressure than at any time since he succeeded Steve Waugh. He won the toss and, rightly this time, decided to bat first.
Matthew Hayden and Andy Gilchrist scored 57 with so little trouble against Darren Gough and Lewis - for whom the ball never swung at all - that Harmison's third over was simply sensational.
He took three wickets in four balls, and a fourth in his next over in a superb hostile spell of four for 13 in five and a half overs. He might have been gifted the first when Gilchrist wafted at a wide one and edged behind but the next two wickets came from detailed homework, although it is one thing to plan and quite another to carry it out.
Ponting's first ball was a reprise of his second ball against Bangladesh the day before at Cardiff - full and slanted in because Ponting tends to fall over offside and play across the line early in an innnings. Bingo and absolutely plumb.
Damien Martyn saved the hat-trick only to be outthought second ball. It was short and wide and he threw the bat to be caught at deep third man by Pietersen.
Lucky for Harmison? No, because the Hampshire man is a brilliant fieldsman and is never put out to graze at third man - except when a catch is expected. Maximum marks for the England think tank for both wickets.
Hayden had watched at the other end but then gave Paul Collingwood the chance to bring off an absolutely stunning catch at point. Harmison dropped short, Hayden bulleted it way over head height slightly to the left of Collingwood.
He flung himself upwards and left, only to realise he had slightly overstretched and, with everything off the ground, turned his right hand back a few inches and clung on. A collector's item.
Mike Hussey (84 at a run a ball) and Michael Clarke (45) then put on 105 in 21 overs and were responsible for a final total of 252 for nine. They targeted England's make-up fifth bowler as shown by Harmison, Gough and Andrew Flintoff's 30 overs costing 119 while 127 came from the other 20 from Lewis and the rest.
Australia's biggest plus of the day was McGrath. He was single-handed as Gillespie started with 11 balls in his first over but he put down a significant marker for the Ashes by bowling out Marcus Trescothick and Andrew Strauss for 16 apiece. Both were undone by lovely late movement back into them, with Strauss looking particularly vulnerable.
Collingwood and Flintoff came and went cheaply and, with Brad Hogg bowling at his best, Michael Vaughan had to struggle for his 57 off
92 balls before the wristspinner nailed him lbw.
When Geraint Jones slogged one from Hogg to long-on, England were on the wrong end of the match - until Pietersen took over to complete two days of misery.
Their defeat by Bangladesh the previous day provided one of the biggest upsets in cricket. Ponting mis-read the pitch and let Australia bat first but sensible batting from Martyn and Clarke gave him 249 to defend.
His problem was that Bangladesh might not know how to set a target but they have enough batting talent to chase one.
Even so, had Australia not gone in with a bowler short or had Kasprowicz and
Gilllespie bowled with any sort of control, they would have won the match. Instead, a glorious century by Mohammad Ashrafal at a run a ball won the match and sent millions of television viewers wild back home. They deserved something from this summer, if only for their unfailing cheerfulness.
As for Australia, successive defeats might suggest the pressing of the panic button but the signs are there that the wake-up calls are being heard; i.e., the bowling of McGrath and the batting form of everyone - except Ponting. Add Shane Warne for the Ashes series but there still remains the form of Gillespie and Kasprowicz to worry about.
