In reply, Pakistan were unable to stitch partnerships as Proteas maintained firm control of the proceedings.
South Africa got off to a flying start with the ball, striking as early as the second over. Ayabonga Khaka provided the breakthrough in her first over when Muneeba Ali mistimed a pull shot and lobbed it straight to mid on.
That early strike set the tone and Marizanne Kapp soon took over with a fiery spell that dismantled Pakistan’s top order.
Kapp trapped Omaima Sohail LBW, removed Sidra Amin in the same over and then dismissed Aliya Riaz just before the end of the powerplay with Riaz falling in similar fashion to Amin. Pakistan slipped to four down before rain interrupted play once again.
The veteran all-rounder starred with the ball while Nondumiso Shangase (2/19) and Khaka (1/14) also impressed in a ruthless team performance.
