Well you'd think that Hopkins would beat out Reece Young (who I don't rate) & Bevan Griggs..and I really hope we don't go back to selecting Chris Nevin.
Jeff Wilson & Bradley Scott are probably shoe-in's at this stage. And I guess McCullum will be battling it out with Wiseman for the spinners slot. I reckon the selectors should take a closer look at Nathan McCullum anyway.
Presuming all international's are available for the match, for the Sth team i'd go with:
Astle, Fleming, B.McCullum, Fulton, Papps, C.Martin, Scott, Wilson, McMillan, N.McCullum, Cumming & (then 1 of Shaw, McSkimming or Schwass)
Nth:
How, Styris, H.Marshall, Taylor, Canning, Mills, Tuffey, Hopkins, Sinclair, Ryder (wildcard as an opener, due to lack of opening depth in the OD's), Vettori & Cairns.
