Looks like Hodge might play in Perth now, given Martyn's
retirement. That's assuming Watson isn't fit, which he probably won't be. In fact, even if he is, he'll have no cricket behind him and they might not pick him until Boxing Day.
I suppose losing Martyn also opens the door for a five bowler policy, if they go that way. I find it a bit hard to see them doing that unless they bring MacGill into the squad, but you never know.
The other option is Jaques in the middle order, but I think they've got him down as a replacement opener instead. If Hodge isn't fit they might go for Jaques at 4, but otherwise I don't think they'd bat him down the order.
