Champion trainer Darren Weir will saddle three runners in the 1400m contest, including last year's winner Black Heart Bar.

Weir will also start Japanese imports Brave Smash and Tosen Stardom.

Caulfield Cup runner-up Single Gaze makes her autumn return from barrier one under Kathy O'Hara.

Other runners include Godolphin's Hartnell, in-form Tasmanian-trained Tshahitsi, Mr Sneaky for Anthony Freedman and last-start Australia Stakes winner Thronum.

Caulfield Guineas winner Mighty Boss is the only three-year-old in the weight-for-age race.
