The match between West Indies and South Africa ended in a draw. But I would say South Africa team played well enough in the match, they had a great performance throughout this test match. As in the first match no team could win despite trying hard, but the match was a draw till the last minute but in the next match both teams will definitely play with their great performance. And I think the second test match will definitely be played by South Africa with responsibility, and they will win their game, performance is good. But West Indies must improve their game and regret their game more, as they are not in very good form at present.
In a Test match, the outcome of the match depends a lot on the performance of the first innings of the two teams. If either team between West Indies and South Africa scored more runs in the first innings, on the contrary, if the other team was all out with less runs, then the team with more runs in the first innings would win the match. If you look at South Africa's second innings performance you will see that South Africa lost only three wickets in the second innings but declared the innings only to win the match. The South African captain might have been confident that they could bowl out the West Indies with the number of runs remaining, but the West Indies batted at an average in 2 innings and managed to save the match. At the end of the match it felt like South Africa may have taken some wrong decisions and that decision went against them but hopefully they will turn around again in the next match.
If a team bats well in the first innings of a Test match, they have a better chance of winning that match, Why do you think that? We often see that many teams are able to win Test matches by batting well in the second innings as well. To do well or win a Test match, any team has to put up a good batting performance in both innings and even give the opposition a target that they cannot topple. In the first test match between South Africa and West Indies, we saw that South Africa batted even better in the first innings. West Indies did not have a promising batting performance in their first innings, but managed to draw the first test match against South Africa with an excellent batting performance in the second innings.
The West Indies cricket team is currently going through a bad time in the Test format. They recently lost the Test series against England and maybe they are trying to improve themselves by learning from that failure. Which may have been reflected in the first match against South Africa, they may try to perform better in the second match as well.
