Sent out at $10 after a disappointing sixth a fortnight ago, the well-bred filly bounced back to shoot through a gap at the 150m mark and claim victory in the Group Two Tea Rose Stakes (1400m) by 1-1/2 lengths from Fiesta ($4.80 fav) .
“He had plenty of horse underneath him,” Lees said.
“They weren't going that quick but he just looked for a bit of room and she really let fly.”
“We know she can do that once or twice a week at home.”
The three-year-old is the fourth foal out of Samantha Miss who Lees trained to win the four legs of the Princess series which culminates in the Group One Flight Stakes in two weeks.
She went on to run third in the Cox Plate as a three-year-old before winning the VRC Oaks.
After she retired, Singleton paid $3.85 million for Samantha Miss.
“She has the brilliance of her mum,” Lees said.
“She just hasn't got the race sense, but it's coming.”
Her jockey Kerrin McEvoy is confident the filly will run the 1600m of the Flight.
“She's obviously untried at the mile, but if we can just get her to switch off she is going to run it out really strong and be really hard to beat in that race,” he said.
“The best is yet to come still. She's an exciting filly to be a part of for sure.”
