Hanseatic and A Beautiful Night have taken out the respective Blue Diamond Previews at Caulfield, with Hanseatic firming as Blue Diamond favourite.

Exciting colt Hanseatic has shown he is on target for the Group One Blue Diamond with a dominant win in the colts and geldings Preview to remain unbeaten.

Jockey Barend Vorster has broken his collarbone in a fall in the Australia Stakes at the Valley.

Rulership has confirmed plans for a Blue Diamond campaign but it is back to the drawing board for stablemate Mount Fuji.
