Dubai: Pakistan closed the opening day of the day-night first Test, played with a pink ball, against West Indies on 279-1 in Dubai on Thursday.
Azhar Ali smashed an unbeaten 146 while Asad Shafiq was 33 not out after Pakistan won the toss and opted to bat in the second ever day-night Test in cricket history.
Ali put on 215 for the opening wicket with Sami Aslam, who fell for 90 in a match which marked Pakistan's 400th Test.
Ali, playing his 50th Test, steered paceman Miguel Cummins for a double to reach his 21st half century. He has so far hit eight boundaries.
Pakistan gave Test caps to middle-order batsman Babar Azam and all-rounder Mohammad Nawaz.
Ali was given a lifeline when Leon Johnson failed to hold onto a sharp chance at gully off Cummins on 17.
West Indian captain Holder brought on his part-time spinner Kraigg Brathwaite in the 15th over and leg-spinner Devendra Bishoo in the 21st but there were no signs of spin.
