Twelve months after producing the quinella in the rich Inglis Nursery, Bjorn Baker has the numbers to go one better at Randwick on Saturday.

The Warwick Farm trainer won the $250,000 race last year with Twilight Royale who narrowly staved off stablemate Fuerza.

This time around Baker will attempt to train the trifecta when he saddles up Baio, Dream Habit and filly Catchtherainbow.

He also has fourth emergency Silent Rush but she is unlikely to gain start and will instead run at Kembla Grange.

"I probably have the two boys on top and then Catchtherainbow," Baker said.

"Baio, he's bringing probably the best exposed form to the race.

"There's not a heap between him and Dream Habit. They both worked really well on Tuesday morning."

Baio was an eye-catching fourth to barn mate Unencumbered on debut at Randwick and was game to the line after being trapped wide when midfield in the Inglis Banner at Moonee Valley.

Dream Habit was beaten as favourite on a slow track at Newcastle at his only start but a firmer surface could yield a different result.

"I don't think he got through it 100 per cent last time and I think on a good track on Saturday we'll see a much better horse," Baker said.

Baker also feels a heavy track inhibited Catchtherainbow when she was down the track on debut at Scone after placing in two city trials.

The Inglis Nursery (1000m) is part of a race series restricted to horses bought at Inglis yearling sales.
