While he passed through a ready-to-run sale without meeting his reserve, two-year-old Salvador is showing enough promise for Wendy Roche to be considering a tilt at a race worth more than 10 times his price tag.

The trainer bought the colt for $46,000 from the Inglis Classic yearling sale with the intention of selling him at their ready-to-run sale, but he was passed in at $55,000.

Roche decided to hang on to the Magic Albert colt - affectionately known as Albert - who is set to make his debut in Saturday's Golden Gift (1100m) at Rosehill.

Roche says the sales-restricted $500,000 Inglis Nursery over 1000m on December 17 is a possible target.

Salvador had his first public hit-out in a barrier trial at Warwick Farm on November 17 when he he finished fourth, crossing the line alongside the Gerald Ryan-trained Pymble and the Hawkes Racing-trained Reflectivity who are both entered in the Golden Gift.

"He weighed 526kg that day. He's not a little boy," Roche told AAP.

Now trimmed to 515kg ahead of his first race, the colt continues to improve, Roche said.

"This horse has always shown promise," she said.

"He has to do it on the racetrack.

"He did it in a trial. It was a synthetic track but he doesn't like the synthetic track so that's another factor."

Roche said Salvador was underdone during his work at the ready-to-run sale where he covered 200m in 10.96.

The sale's top buy, a Written Tycoon colt knocked down at $310,000, breezed up in 10.97.

"My horses just go there to be athletes. At the end of the day if I don't sell them I've got to race them and other people have got to race them," she said.

"They want a racehorse not just a horse that's going to run quick time and then never do anything."

Roche also has Salvador's three-year-old half-brother, a Hinchinbrook colt, who is yet to trial publicly but showing "super" potential.
