Dublin Lass opened at $4.20 but is now as short as $2.50 in the $100,000 event while That's A Good Idea has eased to $2.90.
Another well backed runner at the meeting is Chris Waller's import The Rumour File. The former French-trained galloper will have his first Australian start in the Bedford CA Handicap (1500m) and has firmed dramatically from $21 into $8.
