MULTAN, Pakistan, Jan 18, (AP): West Indies collapsed to 137 all out within one session against Pakistan spinners Noman Ali and Sajid Khan as 19 wickets fell on Day 2 of the first test Saturday.

Pakistan, which got bowled out for 230 in the first innings on a turning wicket, stretched its lead to 202 and reached 109-3 with spinners claiming 17 of the 19 wickets to fall in a day.

Captain Shan Masood (52) raised his 11th test half-century off 60 balls and gave Pakistan a clear advantage before he got run out late in the final session with Kamran Ghulam not out on 9.

Left-arm Ali grabbed 5-39 and off-spinner Khan baffled the top four batters with 4-65 in the middle session on the same pitch where the spin duo had picked up all 20 England wickets in a test match last October.

Captain Kraigg Brathwaite (11) was the only one among the top seven batters to breach the double figures as Khan and Ali bowled all but 14 deliveries before West Indies’ innings folded in 25.2 overs.

West Indies was in disarray at 91-9, but an aggressive counterattacking partnership of 46 runs off 21 balls between Jomel Warrican (31 not out) and Jayden Seales (22) took the visitors beyond the 100-run mark.

It was the second-lowest test innings, in terms of balls, against Pakistan, which bowled out Sri Lanka for 73 in 24.5 overs at Kandy in 2006.

West Indies top-order batters had no clue how to combat the sharp-turning deliveries of Khan, who grabbed four wickets in the space of his first three overs with the new ball.

Khan dismissed Mikyle Louis and Keacy Carty off successive deliveries with the latter brilliantly snapped up in the slips by debutant Mohammad Hurraira.

Khan then had Brathwaite clean bowled after the West Indies skipper went for an ambitious sweep against another sharp spinning delivery and Alick Athanaze offered a low return catch to the off-spinner as the tourists slipped to 22-4 in the fifth over.

Ali then got into the act and edged Khan for a five-wicket haul when he clean-bowled Gudakesh Motie (19) off an inside edge as West Indies got bowled out before tea.
