He doesn't yet appear to be at the Kane Williamson or Ross Taylor level for finding the gaps. Still, 99 is not the easiest time for rotating the strike.
Importantly, Guptill gave the innings structure; a theme of the New Zealand one-day summer. A top order player has regularly taken responsibility in the 50-over format. When Guptill exited, New Zealand were humming at 224 for four in the 38th over. They went at seven and a half an over for the remainder of the innings. The cheap dismissals of Brendon McCullum (0), Corey Anderson (8) and Ross Taylor (18) suffocated hopes of surpassing Australia's record first innings score of 336 for four which New Zealand chased down in February 2007.
Guptill was equal to most short balls although Mohammed Shami got one to kiss the silver fern on his helmet in the second over.
The New Zealand opener lost no courage in the aftermath, hooking and pulling at will on a true batting wicket. All but two of Guptill's 14 boundaries came off pace bowlers.
However, it seems unlikely Guptill's effort and recent Plunket Shield success will be enough for a recall to the starting XI in the tests.
That squad will be announced this morning.
The selectors are expected to opt mainly for the status quo of players who defeated the West Indies 2-0.
