Trainer Troy Corstens says if the Moonee Valley track is downgraded, likely Cox Plate leader Awesome Rock will be scratched.
The track is rated a soft five, four hours out from Saturday’s Cox Plate with more rain and a storm predicted.
Corstens has already committed Awesome Rock to leading the race for which Winx remains the odds-on favourite.
