Chasing a target of 188 runs, Pakistani batsmen proved to be a no show against West Indies' pace attack as Shanon Gabriel destroyed them with a five-wicket haul in second innings.
Pakistan, which leads the three-match series 1-0, is bidding for its first ever test series win in the Caribbean.
That disappointment was replaced by even more jubilation in the West Indies camp though, as Jason Holder replaced Gabriel and immediately earned the prized scalp of Younis Khan. He fell after five balls into the day's play to Yasir Shah, who ended with the magnificent figures of seven for 94.
Pakistan have been in great form as they claimed the top spot in ICC Test team ranking for the first time after levelling the four-match Test series 2-2 against England. All those best laid plans came undone on a famous morning in Bridgetown, with the West Indies needing under 35 overs to blow Pakistan away for 81 and seal an astonishing 106-run series-leveling victory. At one point after tea, they were more than 150 runs ahead with six wickets left and Hope approaching his maiden Test century after coming into bat with an average of only 15.
"We got runs in the first innings which I felt was crucial, and we were able to back it up with a solid second innings performance on that kind of pitch".More news: Airlines to relocate at Los Angeles International Airport

Pakistan captain Misbah-ul-Haq lamented his side's inability to cope with West Indies' bowlers as they slumped to a loss in the second Test.
Joseph should have also accounted for Ahmed Shehzad but the opening batsman, who enjoyed generous slices of luck in scoring 70 in the first innings, was missed at first slip edging an attempted drive.
The hosts lost their last wicket in the very first over of Day-5 after ending the previous day on 264/9. He had half-century stands with Kraigg Brathwaite, Roston Chase and Vishaul Singh.
Playing his ninth Test, Hope had started as an opener two years ago but has started batting in the middle order too.
We had to win the game to keep the series alive.
