After being asked to bat first, Pakistan’s openers, Saim Ayub and Shan Masood, showed grit in the first hour, surviving Kagiso Rabada’s probing spell to reach 36/0. But debutant Corbin Bosch turned the tide with his very first delivery, sparking a dramatic collapse as Pakistan tumbled to 56/4, losing four wickets for just 20 runs. South Africa’s disciplined bowling, led by Bosch and Dane Paterson, left the visitors reeling, though Mohammad Rizwan and Kamran Ghulam fought back with some counterpunching strokes seeing the rest of the session out.
