Trainer Anthony Freedman is set to be two-handed in the two Guineas races on the opening day of the Caulfield Cup carnival.
Both races are for three-year-olds and run over 1600m on October 12.
Freedman said Mark Zahra would ride Super Seth and Kerrin McEvoy Groundswell while Blue Diamond Stakes winner Lyre is to be ridden by Luke Currie with James McDonald on Southbank.
Super Seth and Groundswell finished fifth and third respectively in the Caulfield Guineas Prelude last Sunday with Southbank and Lyre finishing second and seventh respectively in the Thousand Guineas Prelude.
Dalasan remains favourite at $3 for the Guineas with Alligator Blood, who beat him in the Prelude, at $5 while Flit is the $2.80 favourite for the 2019 Thousand Guineas with Hugh Bowman scheduled to ride both.
