Pakistan, requiring 43 runs to win the second Test against Australia, face an increasingly difficult task after losing their seventh wicket for 133 runs in the third session on the fourth day at the Sydney Cricket Ground.
Spinner Nathan Hauritz just claimed his third scalp for the day removing Mohammad Sami for two runs.
Earlier Mitchell Johnson removed Kamran Akmal for 11 runs thanks to the safe hands of wicket-keeper Brad Haddin.
Hauritz took his first two wickets after tea, catching Mohammad Yousuf off one of his own deliveries for 19 runs, and dispatching of Misbah-ul-Haq for a duck.
That was after Doug Bollinger picked up opening batsman Imran Farhat for 22 which was soon followed by Johnson sending Salman Butt and Imran Farhat back to the pavillion for 21 and 7 runs respectively.
Led by Western Australia's Mike Hussey, who set an unbeaten 134 after running out of batting partners, Australia scored 381 in their second innings to set Pakistan a target of 176 runs.
Pakistan are currently seven wickets down for 133 runs after 34 overs, chasing a total of 176, with Umar Akmal facing on 49 not out from 80 deliveries and fast bowler Umar Gul yet to get off the mark.
