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.
