Pakistan were 45-3 in their second innings of the first Test against Australia in Duabi on Tuesday, having an overall lead of 325 runs.
Imam-ul-Haq was unbeaten on 23 while Azhar Ali was dismissed for four in the last over of the day, after Australia were bowled out for 202 in their first innings, conceding a lead of 280 runs.
Earlier Debutant Pakistan off-spinner Bilal Asif led an Australian collapse with six wickets on the third day of the first Test in Dubai on Tuesday.
Australia were all out for 202 after a solid opening stand of 142-0 on a Dubai stadium pitch which started to take a sharp turn.
Pakistan decided not to enforce follow-on and are batting again with a lead of 280 runs.
Pacer Mohammad Abbas claimed four wickets.
It was a total contrast from the pre-lunch session when Australia -- resuming at 30-0 - reached 137 without loss with both Usman Khawaja and debutant Aaron Finch defying Pakistani spinners during their resistance-packed stand.
But the second session belonged to Asif, who dismissed Usman Khawaja (85), Shaun Marsh (seven), Travis Head (nought) and Marnus Labuschagne (nought) in the space of 29 runs.
Pakistan, though, were put on track by Abbas who forced Finch to drive straight into the hands of Asad Shafiq at short mid-on after scoring 62.
Khawaja hit eight fours before miscuing a premeditated sweep and was caught at short leg while Finch had five boundaries and a six in his knock.
Leg-spinner Yasir Shah was unlucky not to be amongst wickets, having dropped Mitchell Marsh off his own bowling for two and wicketkeeper Sarfraz Ahmed missing a stump in the first session with Khawaja on 17.
Earlier in the day Finch was more confident as he punched two boundaries and a six off Yasir before sweeping Asif for a boundary to reach his half-century.
Khawaja, the Pakistan-born batsman, improved upon his previous best score in Asia of 26, made against Sri Lanka at Galle in 2011, by reaching his 13th Test half-century.
