Though if Bailey scores one century in the back end of season in ODIs or Shield cricket you would think he would be a walk up start. The only problem is that he might not play another Shield match and will need to get picked on ODI performances.
EDIT: Just had a look at fixtures there is 4 days break between the Tests and ODIs between Sri Lanka, then 9 days to the tour of India. I don't think there is even a tour game before the first Test. Massive negative for someone likes Bailey and Hussey to have no FC crickets to push his case
