After seeing poor batting of Zimbabwe in first innings its now clear that they won't be able to avoid an innings defeat. Zimbabwe score is 51/1 in second innings while in first innings they lost four wickets when score was 51 runs. If Sean Williams has not scored 83 runs in first innings then Zimbabwe won't be able to score even 100 runs in first innings. Zimbabwe batsmen must try to stay on pitch and try to score as many runs as possible to boost their confidence against top test teams. This series is going to be 2-0 and SA unlucky that this series is not part of WTC.
As South Africa gave huge target of 626 runs, then surely Zimbabwe were struggling to chase it and in the first innings, they were all out at just 170 runs and then they are coming to bat once again and at 51 runs they were already batting at the loss of one wicket.
I think till tomorrow this match will finish and South Africa will win it one-sidedly according to the current condition. However, if we look at the Zimbabwe team level then we can see quite progress this time as they were trying to build a partnership, but as we all know, this would not change the momentum of the game.
