Proteas settled as Aussies panic

The build-up to the second test between South Africa and Australia has exposed the weaknesses of the world number one test nation.

The Australians have admitted to having an under-strength squad and their inexperienced players have not stepped up the way the Proteas' have.

Aussie fast bowler Peter Siddle could find himself in the dressing room after an uninspiring performance in his second test.

Ben Hilfenhaus has been called up to add healthy competition for the position.

Spinner Jason Kreyza did his career no favours by failing to pin down the South Africans, so he'll be replaced by Nathan Hauritz.

It's not only the relative newcomers under pressure after going 1-0 down in the series.

Opener Matthew Hayden has not been scoring freely and received a stern warning from selectors who made it clear that the plan was for him to continue until the Ashes.

Hayden says he'll assess his ! future after the series against the Proteas.

Brett Lee has under performed by his standards and as hard as it may be to believe, the selectors have warned him to find form or face the chop.

Key injuries are also plaguing the home side.

Andrew Symonds may be fit to bat, but he can't bowl due to a knee injury.

Shane Watson is the logical replacement, but he too is struggling with injury.

The Proteas have far less worries.

Ashwell Prince is on the mend and batted through a net session after missing the first test due to a cracked thumb.

The Proteas won't fret too much as JP Duminy has proven to be an able replacement.

Skipper Graeme Smith will bat through the pain barrier, although his elbow injury has had little effect on his ability.

The Aussies are mixing a dangerous cocktail of poor form, injuries and inexperience.

Add a dash of media pressure, on Ponting in partic! ular, and the result could make the home side too tipsy to sto! p the Pr oteas, who are still intoxicated by their confidence inspiring run chase for victory.
