ODI's - Has the ability to bat through, just needs to work on turning the strike over better. Has opened in List A and T20's before.
Tests - If he opened, who bat 3? Taylor seems to be the obvious choice, but still think he goes at the ball too hard, too early.
But I like the potential of a batting line up of:
Ryder (or Guptill/Latham/Broom in the mean time)
