West Indies on their knees in the second Test

Fawad Alam has struck an unbeaten century to put Pakistan in a strong position after the third day of the second Test against West Indies.

The tourists declared their first inning at 9-302 and had the hosts struggling at 3-39 in reply before bad light brought a premature end to play at Sabina Park.

The hosts are 263 runs behind, having lost openers Kieran Powell and Kraigg Brathwaite cheaply, after being put in to bat in the evening session of another day hampered by the weather.

Nkrumah Bonner (18 not out) and nightwatchman Alzarri Joseph will resume with Pakistan needing to make more inroads in a battle against time as they fight to square the two-Test series.

Alam had retired hurt on the opening day on 76 suffering with heat exhaustion and, after rain ruled out play on the second day, had to wait to return to the crease before going on to bring up a fifth Test century as he steered Pakistan past the 300-run mark, scoring 124 not out.

"It wasn't easy," Fawad said. "The conditions were challenging.

"On day one it was hot ... We needed to come back in this Test match, we had to build partnerships as me and Babar (Azam, who made 75) did on the first day."

Pakistan had resumed day three on 4-212 but only eight balls were bowled before play was suspended because of a wet patch on the bowling crease that West Indies felt was dangerous.

Play eventually was restarted after lunch with Jason Holder making inroads with two wickets in successive balls but Fawad kept the score ticking over at the other end.

Jayden Seales was the pick of the Windies bowlers with 3-31 while Kemar Roach with 3-68 and Holder 2-46 also got among the wickets.

After Pakistan declared, Shaheen Shah Afridi removed Powell and Brathwaite as West Indies fell to 2-9 and Roston Chase was then bowled by Faheem Ashraf for 10.

West Indies beat Pakistan by one wicket in the first Test, which was also played behind closed doors at Sabina Park.
