Pakistan trail Sri Lanka by 273 at lunch on day two of the second Test in Colombo.
Sri Lanka were bowled out for 320 runs as Khurram Manzoor and Ahmed Shehzad came in to bat for Pakistan.
Shehzad hit three fours in a row as Pakistan began to build their tally in the first innings.
Rangana Herath bowled a disappointed Manzoor after taking the outside edge as Pakistan were looking comfortable at 47-0.
Shehzad tallied up 21 runs off 18 balls in the first session but Pakistan will not be happy at the early dismissal of Manzoor.
Azhar Ali looked surprised as he came in as number three to replace Manzoor on the stroke of the lunchtime interval.
