New Zealand skipper Brendon McCullum 'frustrated' at continual changing of Kookabura balls in test cricket

New Zealand captain Brendon McCullum has expressed frustration over the continual checking and changing of Kookabura balls in recent Tests, as seven were tried and discarded in the Basin Reserve match against Sri Lanka.

McCullum said that Kookaburra balls have been going out of shape for the last year or two but that the rate's become a 'bit startling'. McCullum hoped that Kookaburra would come up with a fix for it but added that it is a 'bit frustrating' because ultimately the game's meant to be played with a 'round ball' and it makes them look like they are 'whinging a bit about the state of the ball', Stuff.co.nz reported.

However, the skipper said that when the ball starts to go 'square' it becomes a 'slightly unfair game', and added that hopefully that problem would be rectified. Kookaburra Sport group managing director Brett Elliot said that the changes of ball had been noted and came as a 'surprise'. He added that the manufacturing process had not altered in recent years and that Kookaburra had requested New Zealand Cricket (NZC) to send the balls from this Test match to Australia for analysis.

McCullum claimed that the ball does not stay on its axis so to be able to swing the ball becomes difficult because it's not 'fully round'.
