Are England getting the most out of Jonny Bairstow by batting him at seven?
That's the question we asked our Sky Sports Cricket pundits after Bairstow led England's fightback on day one of the second Test with an unbeaten 97 - the tourists closing on 290-8 after being 94-5 and then 164-7.
The 28-year-old is in sight of his fifth Test hundred having previously scored two apiece at numbers six and seven in the order.
Here's how his stats stack up by position, followed by the views of our pundits...
MICHAEL ATHERTON
"Bairstow is perfectly good enough to play up the order as a specialist batsman but given that he is the wicketkeeper, I think that seven is the right position for him - unless you change that and bring someone like Jos Buttler into the side and play Bairstow as a specialist batsman.
"Given that he has that all-round position and is excellent with the tail, seven seems right and I think he feels comfortable there; that's what I've picked up from the England coaching staff. They feel that Bairstow feels most comfortable down at seven."
DAVID LLOYD
"Bairstow is really good at counter-attacking. People will say he's too low at seven but he knows his role and he found an ally in Mark Wood. I thought they played really well.
"Bairstow is very protective of his wicketkeeper role - he really wants that, for all sorts of reasons. England would see him in that Adam Gilchrist role. They used to say in Australia 'why doesn't Gilchrist bat four or five?'
"England aren't out of trouble by any stretch but he's taken the game away from New Zealand."
NASSER HUSSAIN
"Jonny will do whatever is asked of him but I don't think England are getting the best out of him at seven.
"To a degree I agree with Bumble that it's like having Gilchrist at seven - but Gilchrist batted after four or five greats in Langer, Hayden Ponting, Waugh, Martyn. He wasn't really changing if he went up to four or five. Bairstow is coming in at seven after a pretty weak batting line-up.
"Batting him there worked today but how many times are Broad, Wood, Leach going to hang around with him? You are going to have one of your best three players in the side stranded with the tail.
"Yes, he is very good with the tail but as we saw in Australia, if you have some fiery quicks or a wrist spinner then Bairstow could be 20 or 30 and swinging from the hip. He's a better player than that.
"Should he be batting higher? Would he be scoring even more runs? He did brilliantly today with the tail and the tail was brilliant with him - the likes of Wood and Leach at the end.
"Bairstow gets his tempo absolutely spot on with every innings that he plays - whether he has to soak in a bit of pressure or whether he has to go at the opposition with the tail."
JAMES FRANKLIN
"Bairstow doesn't necessarily have to stay at number seven if he wants to keep wicket. It all depends on how much he can handle the workload.
"Personally I'd like to see him bat at five. While he's been in such good form for England in Test cricket in the last couple of years, I don't think England are getting the full utilisation out of him that they could by batting him at seven.
