Prom Queen left trainer Kenny Rae stunned by her performance on her Ruakaka home track yesterday.
The Ruakaka trainer had doubts before the Bear Morgan at Harcourts Bream Bay, but the diminutive filly monstered her three-year-old rivals with an outstanding display to win in a canter.
"I'm in a state of shock. I honestly thought she was vulnerable today," said Rae, who trains Prom Queen with his wife Lisa and their daughter Krystal Williams.
"Last Saturday I gave her a good gallop and she blew too much for my liking. She's got a lot of improvement in her so how good is she?"
Prom Queen was quickly into stride and sat outside the leader to the turn before rider Alysha Collett asked her to sprint and they exploded clear to win easing down by six lengths from Bombard.
