Hayden has looked in pretty good touch to me. Not only has he hit a century, an 80 odd retired and a 70 odd in a 20 over game in the tour matches, but in the ODI against England he was just getting going when he got out to what was, in all fairness, pretty much a freak dismissal. He hit it in the air and everything, but he struck what was a pretty poor delivery very nicely, and Collingwood took a blinder. I don't think his form is a concern right now, I'm more worried about Ponting and Gilchrist really. Martyn, Symonds, Clarke and Hussey have all looked fine.
The concerns right now are the batting form of Ponting and Gilchrist, the bowling form of Gillespie and Kasprowicz, and definately the fielding. I think though that a decent score is around the corner, hopefully on Thursday.
