Pakistan defeated South Africa by three wickets in the last fixture of the four-match T20 series at the Supersport Park in Centurion and clinched the series 3-1. Pakistan, like South Africa, suffered a middle-order collapse as they went from 92-1 to 129-7.However, Mohammad Nawaz kept his cool in the end and was aided by some poor bowling by the hosts, allowing the tourists to cap the tour with a 3-1 T20 series win to go with the ODI triumph earlier this month.
