Boom filly Rostova has made it three wins from as many career starts in today's fillies Blue Diamond Prelude (1100m) and the streak does looks tough to stop as she heads to the main event in a fortnight.

The field for Saturday week's $250,000 MVRC Inglis Juvenile on Tatts Cox Plate Day is beginning to take shape with the announcement that Sydney fillies Our Joan Of Arc and Sheeznodoubt, first and fourth respectively in the Keeneland Gimcrack Stakes (LR) are headed to Melbourne for the inaugural running of the event.
