Group One-winning colts King's Legacy and Tagaloa have been installed favourites in an early market for the $2 million Caulfield Guineas in Melbourne this spring.

The TAB posted its fixed odds markets on Tuesday for a handful of Victorian spring features including the Group One Caulfield Guineas (1600m) for three-year-olds on October 10.

Dual Group One winner King's Legacy, trained by Peter and Paul Snowden, and the Trent Busuttin and Natalie Young-trained Blue Diamond Stakes winner Tagaloa were installed the equal $9 favourites ahead of unbeaten colts Doubtland and Peltzer at $11.

The Lindsay Park-trained Blue Diamond placegetter Personal has been installed the early favourite for the Group One Thousand Guineas (1600m) for three-year-old fillies and is equal favourite at $11 along with the Chris Waller-trained Hungry Heart for the VRC Oaks (2500m).

Unbeaten gelding Cherry Tortoni, winner of the Listed Taj Rossi Series Final at Flemington at his most recent start last Saturday week, heads the early market for the Victoria Derby.

Rising five-year-old mare Mystic Journey, who had a barrier trial at Devonport in Tasmania on Tuesday, is the early favourite for the weight-for-age Memsie Stakes (1400m) at Caulfield at $6 after initially opening equal $8 favourite on Tuesday with Arcadia Queen.

The Memsie, on August 29, is Melbourne's first Group One of the 2020-21 season.
