WHAT THE KEY PLAYERS ARE SAYING:

"He's one that has sort of come out of left field but I reckon he's going all right. This is obviously his biggest test to date to actually see if he's a genuine Group One horse but he gets his chance" - Thronum's jockey Mark Zahra

"She is a good fresh horse and was unlucky when she raced at Caulfield last spring" - Shillelagh's trainer Chris Waller

"I wish the meeting was at Sandown like it used to be as for her it would be a much better track" - Abbey Marie's trainer Mick Kent

"If Black Heart Bart just gets the good run, he's a terribly hard horse to get past" - trainer Darren Weir
