I have seen one problem with New Zealand in this series and that is whenever the target is very big, they do not seem to be able to keep wickets in hand. Just like in this match, there was a huge target. And New Zealand was doing very well to go along by keeping in touch with the run rate. But they were not able to keep wickets in hand. I honestly thought that some unfortunate things happened to them. Losing the first wicket on the second ball of the innings was the first problem. And the problem is they had a few big partnerships here and there. But it was not consistent. With wickets in hand, they should have obviously won the match.
India is looking like a superpower in cricket right now. I am certain that in the upcoming ODI world cup, they are going to be a force to be reckoned with.
India performance in three ODIs is outstanding. If you see batting of India then two times they bat first and both times they score over 350 while one they bowl first they have bowled out New zealand at 108. Coming ODI world cup is also in india and if India maintain this form then surely they will be winner.
