Honestly, someone should put it to Hilditch that he's wasting a place. Probably a bit unkind to Hauritz I suppose to actually say that in a press-conference or wherever, but that's essentially what he's doing.
Hauritz as a bowler offers nothing that North (and Clarke if fit) doesn't. All he does is makes sure Australia's side fits a template, because convention demands that a specialist spinner is picked.
Yet, just a few months back, Australia picked four seamers and won two Tests. Simply beyond belief.
