Tim Paine's Australia, bidding to win their first series in Asia since 2011, are unchanged from Dubai, where they dug deep in an epic fourth innings rearguard to save the match.
Despite the green-tinged strip, Paine said he would also have chosen to bat first.
"I think we would have had a bat, but what's the old saying? If there's anything there, it will be there in the first hour, I guess," the wicketkeeper said.
"We certainly gained a lot from that second innings in particular (in Dubai), so we've got some momentum. Hopefully we can get a couple of early wickets and get right into their middle order."
Teams:
Pakistan - Fakhar Zaman, Mohammad Hafeez, Azhar Ali, Haris Sohail, Babar Azam, Asad Shafiq, Sarfraz Ahmed (captain), Mir Hamza, Bilal Asif, Mohammad Abbas, Yasir Shah.
Australia - Usman Khawaja, Aaron Finch, Shaun Marsh, Mitchell Marsh, Travis Head, Marnus Labuschangne, Tim Paine (captain), Mitchell Starc, Peter Siddle, Nathan Lyon, Jon Holland.
