He seized his opportunity making 137 not out, the highest score by a No 8 on test debut against India at Wellington, and followed with 107 in the West Indies at Kingston. But he's not offering enough with the ball on low bouncing surfaces in the UAE to be guaranteed a third-test place against Pakistan in Sharjah. He's taken one for 63 (when Younis Khan slapped a short and wide delivery to cover) from 29 overs.
If Neesham's candid interviews are any gauge, it won't take him long to recover. He answers questions directly and thoughtfully.
Presumably this same approach applies when it comes to scrutinising his own game. He acknowledged the difficulties left-handers face, and was forthright enough to suggest a 220-230 total would be competitive in the match. He was right.
Judging his Twitter account, there's also a bit of cheek. Not every player is prepared to give the batting coach (Craig McMillan) a lash in taste. "I can take the questionable music blaring through my hotel wall @cmacca10, but if you start singing again I'm calling the police," he wrote.
Fellow all-rounder Corey Anderson has also struggled during this series, but showed better form in the first test with innings of 48 and 23 and his left-armers offer more variation to Pakistan's predominantly right-handed batting order.
Anderson's again moved ahead in New Zealand cricket's version of Andrew Mehrtens v Carlos Spencer. Unless there's a dramatic change in skill-set, this looks set to weave through their careers.
The stance is another reason to pick Ronchi. He's right-handed whereas Anderson and Neesham are left-handers, meaning they're capable of being bowled through the gate out of footmarks used by leg spinner Yasir Shah and left-arm orthodox Zulfiqar Babar, as occurred in the second innings at Dubai.
Ronchi's first-class record is sound against spin, including centuries on New Zealand A tours to Sri Lanka and India last season. In fact, his first-class record is solid regardless of the bowlers.
In 2012-13 he made 807 domestic runs at 62.07, including four centuries. In 2013-14 it was 328 runs at 46.85.
The final say will come down to the selectors but Ronchi might justify a test debut.
