Australia will now heavily depend on Nathan Lyon and Jon Holland to trigger a collapse but with 325 runs already in their kitty, Pakistan will fancy their chances clearly having already caused a psychological dent in the first innings. Australia delayed taking the new ball which eventually worked in Pakistan's favour with both Shafiq and Sohail getting a measure of the surface.
Meanwhile, Wahab Riaz returned to the Test team after a one year gap as the second fast bowler in the team.
Australia's bowlers continue to toil in the blazing Dubai heat, with Pakistan veteran Mohammad Hafeez piling on a century in an ominous start to the first cricket Test.
Part-time leg-spinner Labuschagne finally broke through just before the tea break when he lured Shafiq to drive the ball away from his body and got the thick outside edge to Paine behind the wickets.
107 runs were scored with both batsmen reaching their respective fifties but one wicket was all that the visitors needed to trigger a collapse. Sohail punched Holland to short midwicket and set off for a run.
Pakistan then made a decision to pile on the agony by forcing the Australian bowlers to take the field for the third time in three days by not enforcing the follow on. Sohail, however, couldn't carry on for much longer falling trying to play the late cut to Lyon only to feather it straight into the gloves of Paine for 110, his innings studded with eight glittering fours and two sixes.
Pakistan got off to a strong start against Australia, reaching 89 for no loss at lunch on the first day of the series-opening Test match in Dubai on Sunday. Finch then took on Yasir again, hitting him over the top for the first six of the innings.
For Australia, Siddle was by far the most threatening bowler with the pacer returning 3 for 58 in 29 overs. However, the two have a positive approach and that possibly will see them through.
