Opener Azhar Ali smashed a maiden triple hundred to put Pakistan firmly in control against the West Indies in the first day-night Test in Dubai.
Ali's epic unbeaten 302 guided Pakistan to 579-3 declared before the West Indies closed the second day on 69-1, still needing another 311 to avoid the follow-on with opener Kraigg Brathwaite (32) and Darren Bravo, on 14 not out, fighting at the crease. They lost leon Johnson leg-before in leg-spinner Yasir Shah's second over for 15 but negotiated the pace-cum-spin attack well for 22 overs.
It was Ali who stole the limelight in this second ever day-night Test with a career-best score that was spread over 645 minutes of dominating batting, albeit on a flat Dubai stadium pitch.
It is only the third Test triple century against the West Indies, after Andy Sandham of England and late Pakistan great Hanif Mohammad, making Pakistan's 400th Test, and his own 50th, a memorable occasion.
In all Ali smashed 23 boundaries and two sixes and put on 215 for the opening wicket with Sami Aslam (90), 147 for the second with Asad Shafiq (67) and 165 with Babar Azam (69) for the third.
Ali said he was honoured to join the 300-league.
Ali drove part-timer Jermaine Blackwood to the cover boundary to complete his triple century off 469 balls, pumped the air in jubilation and then did Pakistan's new style of salute and push-up celebrations.
Misbah, unbeaten on 29, signalled the declaration in an attempt to forge ahead in the three-match series.
Meanwhile, West Indies lost the key wicket of Marlon Samuels but made Pakistan work hard and progressed to 211-3 at dinner on the third day of the day-night first test on Saturday.
