"He is best two-year-old colt in Sydney since Pierro," she announced.

The Golden Slipper is only part of the grand plan for Vancouver, which is  unbeaten in two starts following a storming win in the Canonbury Stakes at Rosehill on Saturday.

Waterhouse has made a habit of getting her male Golden Slipper winners to keep going, with Dance Hero and Pierro completing  the triple crown, while Sebring just missed sweeping Sydney's juvenile group 1s,  being beaten by Samantha Miss in the Champagne Stakes.

"The Golden Slipper and hopefully  the triple crown, I'm always thinking  about all of those races together," Waterhouse said.

"I wake up at 1am thinking about my babies and he is certainly one of them. He will go to the Sliver Slippper next."

Vancouver was made a $6 Golden Slipper favourite after lumping three kilograms more than his rivals and giving them a start and a beating. He swooped down the outside to run over the top of Outreach and win going away by three-quarters of a length. Chamarel  filled third a further three lengths away.

Outreach, who started favourite, was particularly brave. He pulled-up lame and was subsequently found to have broken his pelvis.  He will have a long spell and hopefully return as a three-year-old.

The win confirmed Tommy berry's  opinion of the Medaglia D'oro colt, which had won the Breeders Plate in the spring.

"I was always confident that he was very good, but you want to see them do it," Berry said. "He is only going to get better from that.

"It's not just the Slipper, but the Sires [Produce] and Champagne Stakes because as the races get longer  he will be better suited because he is so relaxed.

"What you see now, he will be five lengths better than  that on Slipper day."

There was confidence around several runners in early betting with the TAB laying bets of $45,000 on Outreach at $3.80 and Mawahibb at $3.80, and another of $10,000 at $8 on Chamarel.

Punters shunned Vancouver, which driifted from $3.20 to $5 on track, but Waterhouse was not concerned.

"They were the best males in NSW and he beat them," she said. "He has just got that [Pierro] feel about him. I don't want to compare them  but he has got certain traits that I like to see in a good colt.

"This was his biggest learning experience and he had come through it."

Vancouver shied at the winning post and laid out when he let down in the centre of the track, earning Berry a severe reprimand, but it couldn't temper the jockey's delight.

"Coming to the corner i thought I was travelling well but all the horse around me were starting to niggle and I didn't think I was going to get a run," Berry said.

"He needs that little time to wind up so I just came back off [Ulster's] back and he ate up ground. I had to lose a little ground to make up a lot and did so quickly."

Mawahibb's co-trainer Michael Hawkes believes the colt will get better after running fourth.

"He just got into an awkward position and when they sprinted he was left a bit flatfooted. He will get better from that," he said.
