Fawad Alam's fifth Test century and Shaheen Shah Afridi's new ball potency pushed Pakistan into the ascendancy on a truncated third day of the rain-affected second Test against the West Indies at Sabina Park on Sunday.

Fawad's unbeaten 124 lifted the tourists to 302 for nine declared in their first innings before Shaheen removed both openers swiftly and Faheem Ashraf added another to have the home side at 39 for three in reply at stumps.
