The 2024 CF Orr Stakes will headline Saturday's 10-race meeting at Caulfield in Melbourne, Australia, with nine runners accepting for the first Group 1 since the turn of the year.
Four of those nine combatants have already won Group 1 races, while seven have placed at the top level.
It was recently announced by Racing Victoria that the CF Orr Stakes would be one of the eight qualifying races for the revamped All-Star Mile, which means the winner of this year's race will lock in a start for the A$5 million race.
Mr Brightside will kick off his autumn campaign on Saturday, and he has opened as a -125 favourite with top racing bookmakers.
Ciaron Maher and Declan Bates will combine with Pride Of Jenni (+500), who returns from a spell after an outstanding Melbourne Cup Carnival where she became the third horse to win back-to-back Group 1 races during Cup Week at Flemington.
The Group 1 CF Orr Stakes will be race nine on the Caulfield program and is scheduled to jump at 4:55pm AEDT.
