|Second Test, St Kitts (day four):|
|Pakistan 272 & 377-6 dec v West Indies 223 & 130-5|
West Indies face a mammoth task to save the second Test as Pakistan moved closer to levelling the two-match series after day four in St Kitts.
Hundreds from Taufeeq Umar and Misbah-ul-Haq allowed the tourists to declare on 377-6, a commanding lead of 427.
And the hosts were reduced to 130-5 at stumps as spinner Abdur Rehman (3-26) ripped through the top order.
Darren Bravo (50) provided stubborn resistance until his dismissal while Brendan Nash is unbeaten on 30.
The left-hander will resume day five alongside wicketkeeper Carlton Baugh, but their West Indies' hopes of winning their first Test series in two years look slim at best as a rampant Pakistan bowling line-up seek to wrap up the fragile tail on an increasingly wearing Basseterre track.
The day belonged to Pakistan's overnight batsmen, who resumed on 202-3 with Taufeeq, unbeaten on 97, bringing up his first Test hundred in nearly eight years in the eighth over.
Captain Misbah continued to bat positively, bringing up his 50 off leg-spinner Devendra Bishoo, before launching the onslaught ahead of lunch.
The fourth-wicket duo plundered 63 runs in a 10-over spell before Taufeeq ran himself out for 135.
Misbah maintained his quick-scoring tempo, hitting two sixes as he brought up his third Test century, and his first since taking over captaincy duties.
The 36-year-old was unbeaten on 102 when he declared 40 minutes into the second session, leaving the West Indies an almost impossible target to chase.
And their second innings began in the worst possible fashion when teenage opener Kraigg Brathwaite, making his Test debut, was bowled for a duck by Tanvir Ahmed in the third over.
Lendl Simmons and Bravo thwarted Pakistan's new-ball attack, but could not find a way to thwart the trio of spinners.
Left-arm spinner Rehman accounted for Simmons, caught at second slip by Mohammad Hafeez, swiftly followed by Ramnaresh Sarwan for a duck and Marlon Samuels as West Indies collapsed to 77-4.
Nash and Bravo played with circumspect and caution, with the latter bringing up his fourth Test half century from 139 deliveries.
But the Trinidadian was trapped leg before by left-arm seamer Wahab Riaz four overs before close, leaving West Indies an almost impossible task to save the Test.
