Vettori - an underplayed batsman

In the 2nd innings of the 2nd Test in Sri Lanka, Vettori scored 140 - almost half the side's runs - after coming in at #8.

I have never undestood why he comes so low down in the order - he's a better & more consistent batsman than some of those higher up in the order. In the last 5 years, he is the leading run scorer in Tests for NZ (2127 @ 42.54 in 38 matches/59 innings). Next is McCullum almost 200 runs behind in more matches & innings. (details)

He is also the leading run scorer among all of NZ's current players; and he is #5 in their all-time list after names such as Fleming, Crowe, Wright & Astle.

That is some elite company to be part of, I don't understand why he doesn't acknowledge his own importance and performance and push himself higher up the order. Perhaps he is vary of looking over confident - I'm sure if he wasn't captain, then he would be playing a lot higher. (details)
