West Indies scrambled a pulsating one-wicket victory over Pakistan on Sunday as the visitors self-destructed in the final session of the fourth day when on course to take the first Test of the two-match series at Sabina Park.

Defending a modest target of 168 after they were dismissed in the morning session for 103, Shaheen Shah Afridi led the attack with figures of four for 50 in reducing the home side to 114 for seven at tea with only wicketkeeper-batsman Joshua da Silva and the tailenders left.
