Assuming full fitness (!!) and no late no-shows from the overseas player, I think our team will be as follows (in order of selection):
Two Spinners - Prasanna and White
Opening bowlers - Kleinveldt and Gleeson
Opening batsmen - Levi and Rossington (also w/k)
Next batsmen - Wakeley (as Captain, he won't be dropped), Cobb and Duckett.
So that just leaves two places to fill, and we currently only have two seamers and 2 spinners (plus Cobb). That probably means two from Crook, Procter, Sanderson, Hutton and Buck. For the batting, at least one of them must be Crook or Procter. Whoever is omitted will be unfortunate (and of course Hutton joined us specifically to get more white-ball cricket).
That leaves out Newton (one man in form), Keogh (still our best fielder), Zaib and Vasconcelos.
It's not easy, but I think I'm leaning towards Levi, Rossington, Cobb, Duckett, Wakeley, Crook, Procter, Kleinveldt, Prasanna, White, Gleeson.
In reality, of course, half of these will be injured, so selection will be much easier.
