South Africa have lost two wickets in the second session on day two of the second Test against Pakistan in response to the tourists' 338 all out.
Graeme Smith was dropped at second slip by Younus Khan right at the start of the innings but it did not prove too costly as he was dismissed for 19 after being trapped in front trying to sweep Saeed Ajmal.
He was followed a few overs later by Alviro Petersen, who was caught by Azhar Ali also off the bowling of Ajmal.
Hashim Amla and Faf du Plessis successfully negotiated the remaining overs until tea, with Amla on 17 and Du Plessis on three.
South Africa are on 65-2, and trail by 273.
