Fifties from Babar Azam and Sarfraz Ahmed helped Pakistan extend their lead over Australia to 487 on day three of the 2nd Test at Abu Dhabi on Thursday.

Azam was unbeaten on 90 for his seventh half century while Sarfraz was 60 not out notching up his 16th Test fifty.

Starting the session at 232/4, Pakistan lost Asad Shafiq for 44 with part-timer Marnus Labuschagne claiming his first wicket of the innings. After that, Azam and Sarfraz, who had scored 94 in the first innings, combined for an unbeaten 115-run stand for the fifth wicket in quick time.

Earlier in the day, the first session witnessed a bizarre run-out of Azhar Ali. Batting on 64, Azhar steered a ball from Peter Siddle between gully and the slips and down to third man. After a couple of steps out, he stopped and slowly strolled down the pitch to punch gloves with Shafiq, thinking that the ball would race away to the boundary for four. Mitchell Starc jogged after the ball, saw it hold up before the boundary line and threw it back to Tim Paine who collected it, saw that the batsmen were unaware and broke the stumps while appealing for a run out.

After several reviews the third umpire ruled Azhar out.

This was shortly after Nathan Lyon repeatedly tested Haris Sohail and leaving him frustrated enough to step out for an inside-out shot. He was beaten as the ball spun past his bat resulting in him being stumped on 17.

Shafiq was tentative to start with, edging a few before finally pulling Siddle for a boundary. Marnus Labuschagne also caught attention, hopping while fielding at short-leg that saw him making a meal of an easy catch from Shafiq and then copping a blow on the arm.

Meanwhile, as Azam settled in, he ventured out, smoking two sixes, both against Lyon.

Brief Scores: Pakistan 350/5 (Babar Azam 90*; Sarfraz Ahmed 63; Nathan Lyon 2/130) lead Australia by 487 runs
