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.
It is easy to imagine how competitive a Test match would be with a weak team against the reigning WTC champions. While South Africa declared their first innings on 626, Zimbabwe ended their first innings without being able to avoid a follow-on and began their second innings batting. No matter how well Zimbabwe performs, they will be defeated by an innings. For now, let Zimbabwe gain some experience from the Test, besides, Zimbabwe has basically nothing to learn from this Test.
