South African batsmen cannot be praised. Because they batted in Test matches like ODIs, like Lhuan-dre Pretorius who scored 153 runs off 160 balls. Where there were eleven fours and four sixes. Again, Corbin Bosch who scored 100 runs off 124 balls is still unknown. He hit ten fours. On the other hand, Zimbabwe's Tanaka Chivanga gave away 83 runs off 16 balls. And took four wickets. Again, he took two overs medals.
Given the fact that Lhuan-dre Pretorius is just 19 years old, it was a magnificent achievement by him to score a test hundred on debut. But on the other hand, it was made against the weakest test nation at the moment. And also, let's not forget the fact that South Africa at one point was struggling at 181/6, before the partnership between Pretorius and Corbin Bosch pulled them out of trouble.
South Africa had a bad start against Zimbabwe and if it were not for the Lhuan-dre Pretorius, they could have been a dire situation but the lower order batting century from Lhuan-dre Pretorius and Corbin Bosch as well as a half century from Dewald Brevis put South Africa in a strong position.
They are 418 for 9 at the end of the first day. They can't hope to play much longer but as they still have Corbin Bosch on the crease, he'd try hitting some quick runs very first in the next day's morning session. They'd probably play till the fall of the wicket as its just the 2nd day.
I don't think Zimbabwe would be able to score anywhere near that total.
