Currently, Zimbabwe is performing much worse in cricket than South Africa. At one time, Zimbabwe had the ability to defeat any team. But due to their political situation, cricket is being destroyed in a way. Since then, Zimbabwe has been trying to turn around. And South Africa is currently the Test champion team. And South Africa's cricket structure is much better from which the next players are being produced. Wiaan Mulder was great as a captain in this series. And he did a lot of good as a player, which is why he was named man of the match and man of the series.
There are many differences between South Africa and Zimbabwe in current cricket, especially when it comes to Test series. If it was a T20 match, Zimbabwe might have batted well or they would have come close to winning, but in a Test match, it is quite impossible for Zimbabwe to defeat South Africa. In the first Test match, we saw that South Africa did not lose by an innings, but by a huge margin of 328 runs, but in the second Test match, Zimbabwe's performance has worsened. In the first innings of the second Test match, South Africa made a big collection in front of Zimbabwe and with this collection, they did not get all out, but they declared the innings. Zimbabwe could not make the runs that South Africa made in one innings to declare the innings in two innings. Zimbabwe lost to South Africa by an innings and the margin of that defeat was about 236 runs.
