Alex Brown at SCG rightly stated
Mohammad Asif completed a career-best six-wicket haul as part of Pakistan's broader demolition of Australia that called into question Ricky Ponting's decision to bat first on a Sydney green-top. In union with Mohammad Sami, who dismissed Australia's top three batsmen before the first drinks break, Asif exploited the heavy pitch and atmospheric conditions to full effect to rout Australia for 127 - their second-lowest total batting first at the SCG and worst at home since 1996.
It was because of the disciplined bowling of not only Mohammad Asif and other bowlers but on the whole it was a team's effort, and they showed team work, and they looked with a plan, not like randomly playing with no plan at MCG, where they had a humiliating defeat. Australian media too, created such hype and undue pressure which was shown on Pakistani players on the Boxing Day test match, regarding the visitor's bowling attack, and thus they had won the fight much earlier than the original end of the test match.
But this time, they had miss-cued, and under-estimated the Pakistani bowling attack. Thats why in over-confidence Ricky Ponting after winning the toss on a green-top and over-cast conditions, invited Pakistan to bowl first, in return Pakistan took the advantage and took 10 wickets of Australia first time in an inning for the first time in the series.
But here I am disagreeing with some of the comments of Australian greats that in these conditions even a mid-yorker bowling attack would have succeeded, overshadowing the exampled show of the Pakistani seem bowling, they are usually famous for doing such things, and that's why they most of the time get the unexpected what they had planned, so literally I don't have that much of regret because they can't help it showing their reaction.
On the whole Pakistan this time is playing more sensible than MCG, just keeping the fingers crossed, test match still open and lets pray for the positive result from this test match as we all know winning this test match is important for both teams to improve their rankings, in Pakistan's case it will be slight and only increase or decrease in some points and nothing on the Raking in any case but in Australia's case it will be more as it will either degrade them to 4th spot or will help them retain 3rd position.
