• Australia two wickets from win
• Shafiq scores brilliant unbeaten ton to give tourists faint hope
• Australia skipper Smith drops two catches in slips

Shafiq was dropped on 58 after smashing square to a diving Usman Khawaja and later slashed three runs to point off Bird to complete his stellar hundred.

Bringing a dreadful run of scores, Younus batted himself back into form with a fighting half-century but he fell with an appalling dismissal for 65 when attempting a flamboyant reverse sweep that gave up an easy catch to Smith behind the wicket.

The odds are stacked against Pakistan -- no team has ever successfully chased more than 418 for victory -- but the tourists head into the fifth day with pride restored after their batsmen were routed for 142 in the first innings.
