Talented three-year-old Chateau De Caix has landed a first-up plunge at Doomben but celebrations for trainer Desleigh Forster could be short-lived.

Chateau De Caix, who had no barrier trial form, was the best-backed runner to start at $4.60 in Wednesday's HB Fuller Adhesives Plate (1040m) but only just scraped home to score by a short half-head over fellow debutant San Leon ($18).

Forster, who landed a double at Eagle Farm on Melbourne Cup day, has always had a big opinion of the Dane Supreme gelding who only commenced training three months ago.

He was bought for an undisclosed sum as a paddock yearling by racing identities Andy Pippos and Arthur Harris who have had great success with a number of horses prepared by Forster.

Forster gave Brad Pengelly the riding duties on Chateau De Caix after first-choice rider Shane Scriven was unable to make his 56 kilograms.

"He's only been in work for three months but he's shown ability from day one," Forster said.

"Shane does a lot of his work riding and he's always had a good opinion of him.

"He's very adaptable and can push the button quickly.

"We thought he could win today and we're lucky to pull off a plunge."

Forster and Pippos like the Dane Supreme breed and shared in some early success with some of the sire's progeny.

However, Forster won't be surprised if she loses Chateau De Caix if a suitable sale offer is received.

"I've had a lot of luck with the Dane Supremes but if the right offer comes along I think the owners will sell him," she said.

Earlier, Sydney trainer Gerald Ryan made a flying visit to watch lightly-raced mare Bullion Bay break through for her maiden victory in the Amcor Hummer Convoy Handicap (1200m).

Ryan headed north to inspect his stables at Murwillumbah and some yearlings ahead of next month's Magic Millions sales.

"I wanted to have a look at some of my horses at Murwillumbah to see if they would be ready to race in Sydney or Brisbane," Ryan said.

"I'm also here to look at a few yearlings coming up for the sales."

Bullion Bay cost Ryan $300,000 as a yearling at the Sydney Easter sales but a paddock accident delayed the start of her career.

"She put her foot through a fence and cut her hock as a yearling which is why she never started her career until late," Ryan said.

"She's got loads of ability and I tried to sell her early on but no-one wanted to buy her after she got hurt.

"She's worth a lot more money to me now as a broodmare so I'll just keep racing her."
