The West Indies dismissed first Test triple century-maker Azhar Ali for a duck as Pakistan reached 2-95 at lunch on the first day of the second test on Friday.
Azhar was out in the fifth over off Shannon Garbriel's delivery which ricocheted onto the stumps off the inside edge.
Pakistan captain Misbah-ul-Haq won the toss and opted to bat, but the pitch started to show ominous signs when legspinner Devendra Bishoo knocked back Sami Aslam's leg stump off a ball that turned sharply after pitching way outside the off stump.
Asad Shafiq made a compact half-century and was unbeaten on 54, while fit-again Younis Khan also looked comfortable at 29 not out.
They have added 53 runs together.
Pakistan rested fast bowlers Wahab Riaz and Mohammad Amir from the team which won the first Test by 56 runs, replacing them with Rahat Ali and Zulfiqar Babar.
West Indies had to make one change, when wicketkeeper Shai Hope replaced the injured Shane Dowrich.
