The opening partnership woes are unlikely to be solved this series. Martin Guptill missed yesterday's match with a tight hamstring and Brendon McCullum has been rotated out of the series to keep him refreshed for a demanding summer. That pair will likely open for New Zealand at the tournament. Their average stand of 44.16 in 20 outings at a run rate of 5.43, including eight in excess of 50, makes a compelling case. Even taking out potential outliers at the 2011 World Cup like unbeaten stands of 166 and 72 against Zimbabwe and Kenya respectively and 53 against Canada, the average is still 29.65. They last opened together in the semifinal against Sri Lanka.
However, establishing an injury back-up option is a priority. Anton Devcich and Dean Brownlie have shown promise but that needs fulfilment in the coming weeks. Their fielding skills would also be a World Cup asset. Another option might be to use Tom Latham as a substitute opener, allowing a space in the squad for wicketkeeper-batsman BJ Watling whose value as a closer on the New Zealand 'A' tour to England last year warrants further inspection.
Elsewhere, bowlers Mitchell McClenaghan and Matt Henry need chances to showcase their abilities as much as Adam Milne.
Trent Boult and Tim Southee appear guaranteed World Cup places and, with Kyle Mills' tournament experience such a valuable asset, it appears the McClenaghan/Henry/Milne triumvirate will contest one and, at a push, two spots in the squad of 15 if a spare batsman or all-rounder were controversially axed.
The next ODI starts on Saturday. The International Cricket Council yesterday confirmed that following remedial work, the bowling actions of Sri Lanka's Sachithra Senanayake and New Zealand's Kane Williamson are legal and they can now resume bowling in international cricket.
Both bowlers have remodelled their actions. Tests showed that the level of elbow extension measured for all deliveries bowled was now within the 15-degree level of tolerance permitted under the ICC regulations.
