Coach Andy Flower has stopped short, as is always the case, of directly airing issues of selection in public before the first Test at Dunedin's University Oval. But as he reflected on a performance he described as "sloppy" and "ring-rusty" in England's defeat against a New Zealand XI in Queenstown, he had praise for both Compton and Root.
Compton did much, on his first Test tour in India before Christmas, to vindicate selection as Alastair Cook's new opening partner with a string of determined innings in exacting circumstances. "I thought Nick played really well in India," Flower said.
Root also impressed, of course, with a painstaking half-century on debut at number six as England closed out a historic series win in Nagpur - so much so that many good judges have been prepared to predict his swift elevation in time for next summer's Ashes.
But it was Compton who was given the nod alongside captain Cook in that three-wicket warm-up defeat. He was caught-behind in both innings for an aggregate 22 runs, and effectively bounced out second time round by Mark Gillespie, while Root managed 66 down at number six. That was no endorsement of Compton's credentials, but Flower was hardly hinting at any last-minute change of plan.
He added: "He had some tricky situations to deal with there - some extreme sub-continent conditions, obviously the pressure of playing in India for the first time. I thought he did extremely well out there, without getting the huge score. He put on some really valuable partnerships with Cook."
The best the same pair could muster together at the Queenstown Event Centre ground was a first-innings 45, falling narrowly short of a sixth half-century stand in 10 attempts. Flower added of Compton: "He missed out in this game, having spent a bit of time there in the first innings when the ball was darting around. He's a good player."
As for Root, the coach is wary of a consensus - after an admittedly impressive start to the 22-year-old's international career - which is perhaps in danger of taking future success for granted.
He said: "You've got to remember Joe Root has played one Test match. I think everyone should keep a little calm about his prospects.
"No one knows exactly how he's going to do, not Joe and none of us. But he has handled himself very well in the international competition and the opportunities he's been given so far. We look forward to him having a very successful career, but he's got to take it one step at a time - as do all of us."
