The victory ended a dreadful run of form for West Indies,
who had not won in 17 Tests dating back to February 2009.
Chasing 219 in their second innings for victory, Pakistan
collapsed to be all out for 178 in just 73 overs after they had resumed on 80-3.
Sammy, who has been under fire in the Caribbean, ripped
through the Pakistan middle and lower order, finishing with figures of 5-29.
Ravi Rampaul also took advantage of the difficult batting
surface to take 4-48 as West Indies cleaned up the last six Pakistan wickets
for 43 runs in a low-scoring match where only one player managed to make a
half-century.
West Indies made an early breakthrough when Rampaul clean
bowled Asad Shafiq for 42, ending a partnership that had pulled Pakistan back
from the dreadful start on Saturday evening.
Misbah-ul-Haq continued with Umar Akmal, putting on a 52 run
stand that promised to turn the match decisively in Pakistan's favor.
But Sammy brought himself into the attack and removed
Misbah-ul-haq lbw for 52 before trapping Mohammad Salman in a similar manner to
complete a double wicket maiden that turned the game.
After lunch the wickets tumbled with Sammy and Rampaul
taking full advantage of a surface that offered plenty of movement.
There
were a total of 20 lbw dismissals in the match, a record number for a Test.
