Pakistan vs Windies, 2nd Test: Azhar Ali, Sami Aslam stretch lead to 342 on day 3

Abu Dhabi: Openers Azhar Ali and Sami Aslam hit half-centuries to help Pakistan strengthen their grip on the third day of the second Test against West Indies in Abu Dhabi on Sunday.

Ali was unbeaten on 52 and Asad Shafiq five not out as Pakistan reached 114-1 at stumps, increasing their lead to 342 after dismissing West Indies for 224 in their first innings.

That had given Pakistan a first innings lead of 228 and left them firmly in control as they look to claim an unassailable 2-0 lead in the three-match series.

Pakistan won the first Test -- a day-night affair played with a pink ball -- by 56 runs to take a 1-0 advantage.

But despite the West Indies falling 29 runs short of avoiding the follow-on, Pakistan skipper Misbah-ul-Haq decided not to enforce it and batted again.

Both Ali and Aslam survived leg-before decisions through referrals after on-field umpire Michael Gough had raised his finger on both occasions.

Gough has now seen four of his decisions overturned in the match with fellow English umpire Richard Illingworth forced to change his initial verdict three times.

Aslam was finally dismissed when he was caught behind off paceman Shannon Gabriel for 50, although only after West Indian captain Jason Holder called for a review.

Pakistan will look to stretch their lead even further to leave the West Indies up against it on a wearing fourth and fifth day pitch at Sheikd Zayed Stadium.

Earlier, West Indies added just 118 to their overnight score before they were bowled out at tea with Pakistani leg-spinner Yasir Shah taking 4-86.

Holder (31) and Gabriel (13) frustrated Pakistan with a 27-run last wicket stand before Shah took the final wicket of Gabriel, caught at mid-on to end the innings.

"We are in a commanding position," said Shah. "We know the pitch will help spinners from tomorrow onwards so if we get a lead of 500 then we can press for a win.

"It was good to get four wickets but I was facing a bit of difficulty after bowling with the pink ball in the first Test and then switching to red here."

Shah also dismissed Roston Chase (22) and Shai Hope (11) after lunch while fast bowler Sohail Khan bowled Miguel Cummins (three) to finish with 2-35.

Resuming at 106-4, West Indies lost overnight batsman Jermaine Blackwood in the seventh over of the day when he edged Rahat Ali to wicket-keeper Sarfraz Ahmed after scoring just eight.

Chase and nightwatchman Devendra Bishoo both survived lbw appeals but Sohail had the last laugh as he clean bowled Bishoo for 20, leaving West Indies struggling at 144-6.

The third and final Test will be played in Sharjah from October 30-November 3.
