The pitch is really playing a good role in every match its an easy thing that the subcontinent is always make such a crease mostly in Bangladesh .However Newzealand played really on the last match they won .The series become more interesting now .The next match is schedule on tomorrow .Newzealand will try hard to make it 2-2 on the other hand Bangladesh will try to win the series before the last match .Let's see what really happen on Mirpur in Banglasdesh.
Anything will be a bonus for New Zealand. Remember that they sent such a young team to Bangladesh, and they got whacked in the first two matches. But they came back strongly in the third match, with the Kiwi spinners routing the much more experienced Bangladeshi batsmen. If they could make it 2-2, then it will be some sort of an achievement. And in all probability, it will give a big boost for New Zealand ahead of the T20 World Cup. Also, it needs to be remembered that Bangladesh needs to play the qualifier stage, while New Zealand goes directly to the main stage of the world cup.
You are expecting too much from and a fresh team like NZ. One win by them does not mean they will be able to level the series. Bangladesh whereas is far much experienced and this will be an advantage for them today. I am sure they would come back and win today's match. It is highly unlikely that NZ will win this series.
