David Hayes hoping to get a run at the Melbourne Cup

TRAINER David Hayes thinks the odds are in favour of Unchain My Heart getting a run in Tuesday's Melbourne Cup.

The mare, who has won twice over the Cup distance (3200m) at Flemington, is the last horse in the order of entry (No.24) to get a start, but she would be replaced by the winners of Saturday's Lexus Stakes and Mackinnon Stakes if they weren't already qualified.

"The law of averages is that one of the 24 will get vetted out," Hayes (pictured) said. "Well, that's what I'm hoping for. Could there be 24 horses that are perfectly sound?"

Unchain My Heart ran second last in the Caulfield Cup (2400m) 12 days ago, but Hayes said the eight-year-old needed more distance.

"Her record over 2400 metres is not that good, but stretch her out to 2600 metres and beyond and she really performs," he said.

Hayes has nominated her for the Lexus as a back-up if no Cup hopefuls are scratched before Saturday.
