At the MCG on the first morning of the Boxing Day Test between Australia and Pakistan, he finally struck, right on the cusp of lunch.
The Boxing Day Test would be followed by third and final Test at Sydney Cricket Ground from January 03 to 07, 2017 between Pakistan and Australia.
Azhar was outstanding, with is 100 making him only the fifth Pakistan player to score more than 1000 runs in a calendar year.
Pakistan's opening batsman Azhar Ali has rarely seemed a man in a hurry in six years of test cricket so it was fitting that his 12th century was eked out in fits and starts over two rainy days at the Melbourne Cricket Ground.
The tourists are not expected to tinker with their batting after a heroic effort which took them within 40 runs of what would have been a world record win in last week's Brisbane series-opener. Centurion from the first Test at Gabba, Asad Shafiq, took strike to face the last ball before drinks during session one.
Azhar and Asad Shafiq, 48 not out, batted stubbornly in hard conditions to share a steadying 107-run stand for the fifth wicket after the tourists had stumbled to 112-4 after winning the toss.
Mascot's dive leaves Allardyce fuming
Allardyce has now taken charge at Selhurst Park, with Palace themselves battling to keep hold of their Premier League status. The Hornets captain was left out of the side against Crystal Palace but came on early for the injured Valon Behrami.
Ali, at the other end, had to scramble a bit but managed to get his bat back into the crease.
Australia retained the same side which won the first Test in Brisbane after Pakistan just failed to produce the greatest run chase in Test history.
The bowling unit of this team has been brilliant with the pace trio of Starc, Hazelwood and Bird picking up the wickets at the regular interval. If this remains the case on Day Three, it will be interesting to see what Pakistan are able to achieve in about 50 overs on a wicket which has been assisting the batsmen.
Most pressure will be on the left-handed Maddinson, who is fighting for his place in the XI after scores of zero, one and four in his first two Tests.
Having previously scored all his centuries on Asian pitches, Azhar's knock at the MCG added to the 139 he scored in Birmingham in August in a losing cause against England.
With the forecast not looking brighter for the remainder of this Test, the chance for Pakistan to level the series is also dwindling.
