Unlike us where we can have two $1.30 pops lose at the same meet and nobody bats an eyelid, the gallopers do not expect their odds on faves to lose.
Craig Williams is being investigated and chastised over his ride on Nature Strip in R5 at Caulfield yesterday - the suggestions seems to be that he stopped the horse from leading (from barrier 1)
I know the replay angle is tricky but it looked to me like he was never going to lead and Williams had to take hold when crossed

I get the feeling that jockey scrutiny is tougher than driver scrutiny
