BASSETERRE: West Indies' bid to claim a rare series success was in jeopardy after Pakistan wrestled away control of the second Test in St Kitts.
After belatedly bowling out Pakistan for 272 the hosts faltered in the face of a three-pronged spin attack to reach the end of the second day at 184 for eight.
Slow men Abdur Rehman, Saeed Ajmal and Mohammad Hafeez each took two wickets as the hosts relied on a half-century from Marlon Samuels, on his return following a two-year ban, to just about keep them in a game they must avoid defeat in to win the two-Test series.
But on a waring track, on which 12 wickets fell today, a result looks likely to leave West Indies with an uphill task with the prospect of an first-innings deficit looming.
If they are to trail they can blame a defiant last-wicket stand between Pakistan duo Tanvir Ahmed and Ajmal this morning when they added 78 runs to frustrate their hosts.
West Indies had looked like they would make light work of the Pakistan tail when they took three of the four wickets they needed at the start of the day inside the opening half-hour.
But they were met by firm resistence thereafter, led by Ahmed who reached his maiden Test half-century before he was trapped leg before by Devendra Bishoo (three for 80) for 57.
Ahmed immediately followed his heroics with the bat when he opened the bowling, removing Lendl Simmons with the second ball of the innings edging to Taufeeq Umar at second slip.
Umar was called on again moments later to hold a juggling chance when teenage debutant Kraigg Brathwaite (15) nicked an angled Riaz delivery.
Pakistan's spinners then took over as West Indies crawled along, with Darren Bravo most painfully watchful, at barely a run an over during the afternoon session.
Rehman's eight overs before tea cost just 12 runs while Ajmal allowed just 14 from 10 overs including the fortunate wicket of Ramnaresh Sarwan.
Sarwan (20) was stumped after he drove into his front pad and the ball ricocheted back to wicketkeeper Mohammad Salman to catch him out of his ground.
Pakistan were deservedly rewarded a fourth time before tea when Bravo's patience was finally broken with the last ball before the break, edging Hafeez to slip after scoring 24 from 87 balls.
West Indies' slipped further into trouble after tea as Brendan Nash and Carlton Baugh fell to Hafeez and Rehman to leave them 107 for six.
Amongst the steady flow of wicket Samuels provided the few highlights for the hosts, launching a couple of eye-catching sixes straight to break the shackles of the spinner.
His skipper Darren Sammy tried to follow suit but it proved ill-advised as he was brilliantly caught by Umar Akmal, who checked his momentum just before the boundary rope, off Rehman.
Pakistan then claimed the crucial wicket of Samuels for 57 when Taufeeq rushed in from long-off and held on just above the turf to give Ajmal his second scalp and leave West Indies in trouble. AGENCIES
