The only filly in Saturday’s Sportingbet South Australian Derby, Scratchy Bottom, is the big firmer for the Group 1 feature race at Morphettville.

Scratchy Bottom has shortened from $10 into $8 third favouritism at and has been the best backed to beat the $4 favourite Order Of The Sun.

“At this stage Scratchy Bottom is our worst result and if the cash continues she’ll be starting shorter than $8 on Saturday,” William Hill’s Andrew Brown said.

“Fillies don’t have a terrific record in the race but she will certainly stay the trip.”
