First Test, Barbados, day four: West Indies 345 & 371 bt Pakistan 144 & 296 by 276 runs
Gayle secured his second five-wicket Test haul
Chris Gayle captured five wickets as West Indies dismissed Pakistan for 296 to win the first Test by 276 runs, only their second victory in 19 matches.
Shahid Afridi, dropped off the first ball of the second over as Pakistan chased 573, smashed a brutal 122 before he was ousted 10 minutes before lunch.
Abdul Razzaq looked in control with four fours and a six in his 41 but the third umpire adjudged him stumped.
The final four wickets fell to Gayle for 22 within nine post-lunch overs.
Afridi should have been dismissed on 35 at the start of the day but Devon Smith spilled it at long-off, Gayle the unfortunate bowler.
Having lost Asim Kamal for 55, Afridi hit a series of savage blows, mainly over mid-wicket and reached his century by charging down and lofting for four.
He finally fell for 122, spooning a catch to Shivnarine Chanderpaul at extra-cover.
Having reached his seventh Test fifty with an edge through the slip cordon, Kamal fell to Gayle via wicketkeeper Courtney Browne's cap, the ball deflecting to Smith at slip.
Razzaq also enjoyed a moment of fortune at Gayle's expense, when, having made only a single, he edged the spinner through Browne's gloves.
Afridi pulled Corey Collymore for six to record his half-century.
He continued to be severe on the fast-medium bowler, pulling him for another six over mid-wicket for another six and straight driving the next ball for four.
His fourth six of his innings was a huge swipe off Gayle that landed on the roof at mid-wicket and took him to 97.
The century was reached in fine style as he advanced down the wicket to medium-pacer Daren Powell and hoisted him over mid-off, the ball pitching within inches of the boundary rope.
After passing three figures he launched Gayle for successive sixes with his favoured slog sweep.
It was Razzaq's dismissal that ended Pakistan's resistance, the third official taking a lengthy period to deem that the batsman's foot was on the line and not behind it as Browne whipped off the bails.
Skipper Chanderpaul, named Man-of-the-match for his unbeaten 153, looked forward to the final Test in Jamaica on Friday.
"We've been lacking a bit of confidence, this should help us," he said.
Fidel Edwards was unable to bowl on the fourth day after straining a thigh muscle and he and Dwayne Bravo will be monitored ahead of the next match.
