Trainer Kris Lees has put the polish on many elite horses with Graff working his way to the top of the list after keeping his unbeaten record intact in the San Domenico Stakes.
Samantha Miss is at the top of the tree but Graff's first appearance as a three-year-old has stamped him as a star.
The two looked as if they would fight out the finish until Graff stamped his authority on his rival to beat him by 2-1/2 lengths.
Performer ($5.50) was another 1-1/4 lengths third.
“He's the best colt I've had anything to do with,” Lees said.
“I'm really pleased with how he's come back and I think there's some nice races in store for him.
“When he won at Hawkesbury he just thought about things so we put the blinkers on him.
“He's a pretty serious horse and he'll go to the The Run To The Rose and then to the Golden Rose.”
The TAB reacted by slashing Graff's price from $51 to $8 for the Group One Golden Rose (1400m) on September 22.
The colt's owner Alan Bell rated Graff as good as he has had while Graff's jockey Jason Collett was also upbeat.
“That was quite easy in the end,” he said.
“He started to really pull me into it 700 to 800 metres out and I thought ‘ease up boy'.
“He's a bit of lad and physically there is still improvement to come.”
