Fawad Alam and Azhar Ali battled through the morning session unscathed on day two against the Proteas as Pakistan reached the lunch interval on 104-4.
The Proteas applied late pressure on Tuesday, which had Pakistan start the morning’s action on 33-4 and in a spot of bother.
Alam and Ali, though, fought bravely to avoid any further damage to the home side’s total, while the Proteas bowlers struggled for a breakthrough.

Kagiso Rabada’s wait for his 200th Test wicket continued as Keshav Maharaj and George Linde were called on before the break, hoping to pick up a much-needed wicket.
Two unsuccessful reviews by captain Quinton de Kock didn’t help the visitors’ cause either.
Alam (39) and Ali (38) will resume their partnership on 77 after lunch.
