Rawalpindi: Opening batter Imam-ul-Haq hit a century in each innings for Pakistan as Australia could bag only four wickets on a docile pitch in the drawn first test on Tuesday.
Imam followed his 157 in the first innings total of 476-4 declared with an unbeaten 111 in his first test since November 2019.
Imam's opening partner, Abdullah Shafique, also prospered to record his maiden test hundred and was unbeaten on 136 when Pakistan finished the fifth and final day on 252-0 in its second innings, leading by 269 runs.
Both teams mutually agreed to end the game with an hour remaining.
Shafique hit 15 fours and a six in his 242-ball knock while Imam was more watchful in raising his hundred and faced 223 balls, hitting seven fours and two sixes.

The second opening stand between Imam and Abdullah surpassed Pakistan's previous best against Australia in 1964 when Khalid Ibadulla and Abdul Kadir combined for 249 in Karachi.
Shafique and Imam also became the first Pakistan opening pair to share a century stand in each innings against Australia after combining for 105 runs in the first innings.
It was a tough start for Australia to resume playing test cricket in Pakistan after 24 years on a benign Pindi Cricket Stadium pitch which didn't offer any lateral movement to the visitors' three frontline pacers or turn to ace spinner Nathan Lyon.
