The next match will be very competitive. The South African team lost the first match. They will find out their mistakes and correct the mistakes and make the team more stable for the next match. Pakistan will have to be stronger if they want to beat South Africa in the next match.
Pakistan might be making pitches that will help their spinners and if that is the case it will be difficult for South Africa until they have a batsman that could counter spin, in the past they had players who played well against spinners but in the current team we are yet to see any players who perform well against spin.
