A capacity field of 16 has been declared for the Group One Blue Diamond Stakes at Caulfield.

Of the 16 two-year-olds in Saturday's Group One race over 1200m, nine are fillies.

The Ciaron Maher and David Eustace stable holds the strongest hand with six runners - Ideas Man, Rathlin, Tanker, Away Game, A Beautiful Night and Muntaseera .

The Lindsay Park team of David and Ben Hayes and Tom Dabernig will be represented by three fillies, Aryaaf, Personal and Riverina Storm while the Trent Busuttin and Natalie Young stable has dual representation with colt Tagaloa and filly Letzbeglam.

Unbeaten Hanseatic, chasing consecutive Blue Diamond victories for the Anthony Freedman stable, is a clear-cut favourite from the Peter and Paul Snowden-trained Rulership.

Like last year's winner Lyre, Hanseatic races for Godolphin.

The barrier draw will be held on Tuesday morning.
