Brendon McCullum's days as a wicketkeeper appear ever-diminishing if the series in England is a gauge. He may have donned the gloves for the last time in international cricket.
He delegated the task to Luke Ronchi and Tom Latham in the 50-over and 20-over matches respectively and, if it hadn't been for a B-J Watling knee injury, wouldn't have taken the gloves in the tests.
It makes for a logical transition. McCullum remains one of New Zealand's best fielders. He underlined that with a catch at second slip off Michael Lumb from the two balls bowled by Mitchell McClenaghan in this morning's second T20 international at the Oval. The match was abandoned from that point due to rain.
"It's something that needs discussing," McCullum said after New Zealand secured a 1-0 T20 series victory to go with a 2-1 win in the ODI series and a 2-0 loss in the tests.
"[Being a specialist batsman] is an option if we can balance the team right.
