The Bryan and Daniel Guy training partnership has had plenty of success since forming 14 months ago and has a genuine chance of a first Saturday-class metropolitan double at Doomben.

The father-and-son team formed their partnership in September last year and have had 41 winners.

Daniel Guy said the stable had gone well considering it didn't have many city-class horses.

"All stables have those times when you don't have too much heavy ammo. But we have been building up our younger stock and we have high hopes for them," Guy said.

Two of those horses are three-year-old Nashville Skyline who runs in Saturday's No Cracks Plumbing Handicap (1600m) and two-year-old Animal Spirits, an acceptor in the Sky Racing Handicap (1200m) at Doomben.

Nashville Skyline was a Gold Coast winner first-up and then finished third at the Sunshine Coast last start.

"The Three-Year-Old on Saturday is a strong race but we are getting a bit of weight off some good horses," Guy said.

"The 1600 metres will suit Nashville Skyline but we plan to get her out to 1800 metres next time and then I think you will really what she can do."

Animal Spirits beat top two-year-old Blue Book in a trial and then was a well-beaten third behind that horse in her first start at Doomben.

"The track was very heavy and she was under pressure a good way out. I think getting out to 1200 metres and a drier track will suit her. She is getting a bit of weight off Blue Book but he looks very smart," Guy said.

"Still we are there with a hope of a double on Saturday and both horses have bright futures."

Before Guy officially joined his father in partnership, the stable won the 2016 Queensland Derby with Eagle Way who was then transferred to his owner John Moore in Hong Kong.

Eagle Way runs in Sunday's Hong Kong International Vase (2400m) with Derby-winning jockey Tommy Berry to ride.
