Younus Khan led Pakistan's fightback with a dogged century after the hosts made a terrible start to the first Test against Australia in Dubai.
After opting to bat first, Pakistan reached 219 for four at stumps on the first day with captain Misbah-ul-haq (34) and Asad Shafiq (nine) at the crease.
The 36-year-old Younus fell on 106, leg-before to Australia pace spearhead Mitchell Johnson's second delivery with the second new ball.
Younus walked in at number four with Pakistan having lost both their openers before the total had reached double figures.
The stylish right-hander propped his side up with a 108-run stand for the third wicket with Azhar Ali (53) and then added 83 for the next with Misbah.
He hit 10 fours during his 223-ball knock and got to his 25th test hundred with a huge six off spinner Nathan Lyon over mid-wicket.
Pakistan, without banned off-spinner Saeed Ajmal, handed Test debuts to fast bowler Imran Khan and leg-spinner Yasir Shah in a new-look bowling attack.
Australia also handed first caps to fast-bowling all-rounder Mitchell Marsh and left-arm bowler Steve O'Keefe, who paired up with Nathan Lyon in a two-pronged spin attack.
Australia will reclaim the world number one test ranking from South Africa with a 2-0 win over Pakistan, who host matches in the United Arab Emirates due to security concerns back home.
