45-3.
Younis (three) charged down for a sharp single after tapping a ball from Angelo Mathews to mid-wicket, but failed to make his ground at the non-striker’s end as Kaushal Silva threw down the stumps.
Azhar and Asad Shafiq repaired the early damage with a 46-run stand for the fourth wicket on either side of a 19-minute interruption for rain early in the post-lunch session.
Shafiq fell in the second over after resumption for 15, playing back to a full-pitched delivery from Prasad and was given out leg-before.
A heavy downpour for the second time forced the umpires to call for an early tea, but Pakistan’s woes just refused to end as the next three wickets fell for 17 runs in five overs.
Azhar was on 49 and Pakistan still 158 runs behind when he was reprieved by TV umpire Sundaram Ravi after on-field official Paul Reiffel had declared him caught behind off Prasad.
But Azhar only managed to add another three runs when he edged a drive off Pradeep to be snapped up by Dimuth Karunaratne at second slip.
Pakistan captain Misbah-ul Haq, who came in to bat at number seven due to a mild groin strain, became Pradeep’s third scalp when he was given out leg-before after making six.
