Australia, in reply to Pakistan's 282 all out, were 20-2 at close on the first day of the second Test in Abu Dhabi on Tuesday. Pakistan had tightened its grip in the first Test; however, responsible batting display by Australian Usman Khawaja and Tim Paine in the second innings deprived Pakistan of sealing a Test victory in UAE after two years.
Abbas, who was also Player of the Series in Pakistan's previous Test series in England, said the key to his success was understanding the conditions, keeping it simple while bowling wicket to wicket, and waiting to take advantage of reverse swing.
Pakistan ended day two in a dominant position with a lead of 281 runs, as Azhar Ali and Haris Sohail remained unbeaten at stumps.
Hafeez, who scored a hundred in the drawn first Test in Dubai, fell to a lazy shot off pacer Mitchell Starc, caught at short mid-off for six.
Pakistan were down and out at 57-5 at one point in the match but Fakhar Zaman (94) and Sarfraz Ahmed (94) struck a big partnership to get Pakistan out of trouble.
Ahmed was, by far, more aggressive, and kept the scoreboard moving with constant rotation of the strike before his 129-ball knock was ended in which he hit seven boundaries.
94 - Fakhar Zaman became only the 4th Pakistan player and overall the 31st to be dismissed in the 90s on Test debut.
"Yes, our position is good", said Zaman.
Hamza bowled one over late in the day, but Abbas got both strikes, getting Khawaja caught behind down the leg side for his 50th test wicket, and trapping Siddle.
Where will be the second Test between Pakistan and Australia be played?
"I was with the squad from the start but during the first Test I was about to return to Pakistan before, unfortunately, Imam-ul-Haq got injured and I got this chance of playing my first Test".
Australia's hopes of salvaging a test hurtling towards an early finish crumbled when Marnus Labuschagne (25) was run out in freakish circumstances after lunch.
Abbas, whose first wicket of the match made him the joint second fastest Pakistani to 50 wickets, gave Pakistan an early wicket in the fourth over of the day, removing Marsh with a catch in the slip.
Then, he followed it up with the wicket of Travis Head (14) and left Australia 56/4.
