So far:
Jaques out for 9
Rogers out for 24
Hughes 46* (big opportunity to put himself in the box seat)
Klinger yet to bat
(no other realistic chances i wouldn't think)
The spinners spot is also up dfor grabs and Krezja and Hauritz are going head to head. They both get to bowl on the same pitch and show what they've got. Mcgain will also have a chance to impress against SA and who knows with a good performance he could leapfrog both of the others.
So far:
Krezja 0/21 off 10
Others yet to bowl.
The allrounder/middle order batsman position is also there for the taking. McDonald would need a big game you'd think. Symonds has a chance to impress and get himself back in the team. There are a host of others around who also have a chance including North and Klinger (yes i know i mentioned him in the openers spot but he isn't without a chance of getting in at number 6). Marsh and D. Hussey who are in the ODI side aren't without a chance either.
So far:
Symonds out for 5
No others have had a chance as yet.
The fast bowlers will realistically be selected from who is left standing. Most of them are injured and there is not a lot of choice. Basically anyone on the fringe that is fit will probably get a tour. Bollinger has his chance to grab a spot. Basically to grab a spot he just needs not to get injured. Will Siddle and Lee be fit in time? Johnson will have a massive workload in SA and i hope he doesn't break down. Hilfenhaus and Bracken are a chance too you'd think and if any more blokes break down even Ryan Harris could get a call up

This will be a very very interesting round of Shield cricket.
