Well what would have Australia lost if not for the match against New Zealand in the finals ODI of the bilateral series when the series has been pocketed by them a couple of days ago? Aussies made the most of it when they seriously had to win though they lost the first encounter which would have seen them go 1 down in the series. However, that was the match where both the teams fought in a very tight manner and as the convention goes, there could be only one winner and that happened to be New Zealand. And, then onwards, it has been the Aussie show until they sealed the series against their name.
And, there should be absolutely no reason for New Zealand to rejoice their victory in the 5th one dayer played at Wellington despite winning the match be a rather decent margin of 51 runs. This can be considered as Australia's loss and not a win by New Zealand for it was not New Zealand who fought for it. The match was gifted by Australia to New Zealand for which New Zealand has to be thankful to their Tasmanian rivals. However, things didn't start as though New Zealand would win the match when they lost 4 wickets for a score less than 100 on the board.
The score was 25 by the time the 2nd wicket had fallen and scorecard suggests that the New Zealand openers - Brendon McCullum and Martin Guptill had scores of 1 and 7 respectively. New Zealand could score a total which was only somewhere near to the total that they could manage in their earlier games. In the 4th ODI at Auckland, they ended up scoring 238 runs and in the 3rd ODI at Hamilton, they were found to score just 245 runs compared to the 241 they put up in the last one dayer which they appeared to win convincingly.
One has to wonder as to how come New Zealand could manage to defend a similar total in the inconsequential match at Wellington when they could not even come close to doing the same in the previous one dayers at Hamilton and Auckland respectively. And, the way Australia played was just another instance of a captain's immaturity when Ponting went into the fifth ODI with a full strength Australian team when he could have rested some senior players like Watson & Johnson and instead played some lesser talent like Bailey. Neither did Ponting go in for a whitewash nor did he give some lesser talent a little bit of match practice.
