Not wanting to take anything away from an amazing Australian performance, Hughes in particular, but South Africa's batting lineup has been looking significantly flat this series. Perhaps its due to Smith's lingering injury keeping him from really leading the charge, a lethargic approach to the series burdened by home pressure and overconfidence or lesser comparative matchplay since the two sides have met. However - whatever the cause - Australia may have appeared vulnerable over the last summer with poor performances against India in the sub-continent and a series loss against South Africa at home, but they've proven this far into the series that they are still a world class team which requires maximum effort to be outmatched.
Dave will be chafing; Phil could be the new "Hughesy" if he keeps this up for the next year or so.
