Pakistan were 38 without loss in their second innings at close on the third day of the first Test against Australia in Dubai on Friday.
Ahmed Shehzad (22) and Azhar Ali (16) were at the crease as Pakistan increased their lead to 189 runs at Dubai stadium.
Earlier, Australia were bowled out for 303 in their first innings, conceding a big 151-lead to Pakistan, who had made 454 in their first knock.
Opener David Warner scored 133 while Chris Rogers made 38 and Mitchell Johnson 37.
Debutant leg-spinner Yasir Shah took 3-66 while paceman Rahat Ali (2-55) and left-armer Zulfiqar Babar (2-81) also chipped in with useful contributions.
Michael Clarke failed with a 13-ball two and so did Alex Doolan (5).
It was Warner who anchored the innings, becoming seventh Australian batsmen to score three consecutive hundreds, the feat last achieved by Adam Gilchrist (2005) and Bradman (1948). But with his third ball after lunch, Shah spun sharply to bowl Warner, who had hit 11 fours and two sixes during his 174-ball knock, but his fall saw Australia slump against spinners.
Mitchell Marsh (27) and Brad Haddin (22) took Australia to 248-5 during their 42-run stand for the sixth wicket but Pakistan broke through with the new ball, taken as soon it was due after 80 overs.
Paceman Imran Khan (1-54) had Haddin bowled off an inside edge while Babar had Marsh lbw.
Warner saw Australia lose Chris Rogers (38), Doolan and Clarke in the space of just 30 runs before he and Steven Smith (22) added 48 for the fourth wicket.
Warner drove Khan to cover boundary for his eighth four to complete his hundred off just 128 balls. The left-hander had hit a century in each innings against South Africa at Cape Town in Australia's last Test in March this year.
Australia, resuming on a strong position at 113-0, lost Rogers when he played on to seamer Rahat Ali. Rahat was again involved when his direct throw from mid-on found Doolan short of his crease as he attempted a sharp single.
Clarke, short on match-practice after failing in the warm-up game, survived just 13 balls before giving a bat-and-pad catch to short-leg off Babar.
Smith helped Warner to take the score to 206 before he fell in the penultimate over before lunch, playing straight into the hands of point to give Shah his first wicket.
Pakistan took another four wickets in the post-lunch session and despite Mitchell Johnson (37) and Steve O'Keefe (six) adding 32 for the ninth wicket, wrapped up the innings with 15 overs remaining in the day.
The second and final Test starts in Abu Dhabi from October 30.
