In four previous starts before the Grand Prix, Vilanova had been a regular in the stewards' reports for slow starts and mid-race incidents which hampered his progress.
He showed his promise when he ran second in the BRC Sires' Produce Stakes a year ago and Waller ended up with the same result when Brazen Beau missed the start on Saturday and ran second to Time For War.
That didn't alter bookmakers' opinions with Brazen Beau still the $2.50 favourite for the group one JJ Atkins (1600m) on Derby Day.
Randwick winner Almalad firmed to $6.50 second favouritism to give Gai Waterhouse consecutive wins in the final group one 2-year-old race for the season.
Almalad goes to the JJ Atkins at just his third start but Waterhouse says that is no problem nor is the distance rise from 1200 to 1600m.
"It won't worry him. He is a very exciting horse."
