Sydney trainer Gary Portelli will unveil a ready-made Melbourne replacement for a retired stable warhorse on Tuesday morning.

It was only last week Portelli and his brother Troy drew the curtain on the eight-year racing career of top sprinter Marwin Gold.

Marwin Gold bowed out of racing as a rising 12-year-old by winning at Moe and the Portellis haven't taken long to put more youthful legs into their satellite stable.

Sheeznodoubt will play minor role during Tuesday morning's Breakfast With The Best at Moonee Valley but her gallop will be crucial ahead of her Melbourne debut.

"She's had a good grounding since she's been in Melbourne but having her first look at Moonee Valley will be a test for her," Troy Portelli said.

Sheeznodoubt will line up in the $250,000 Inglis Juvenile (1000m) on Saturday with Sydney's premier jockey Blake Shinn taking the ride.

"If she is half as good as Marwin Gold the stable will be happy," Portelli said.

"We worked it out that Marwin Gold won on average $50,000 each preparation he had. He was an owners' dream."

Sheeznodoubt finished fourth on debut after leading in the Gimcrack Stakes at Randwick on Epsom Handicap day.

If there was any stable disappointment over the run, it has quickly been erased by subsequent results in Sydney and Melbourne.

Runner-up Horizons won at Randwick on Saturday and the third placegetter Come Hither scored at Caulfield on Thousand Guineas day.

From further back in the Gimcrack field, Movie won on a seven-day back-up at Rosehill last Saturday week.

"Our filly jumped a bit awkwardly and she had to be used up to keep a position," Portelli said.

"The first part of the race was run very quickly and we certainly had no intention of going that hard.

"Under the circumstances we thought her run was very good."

The Portelli stable will have two-year-old runners in two states on Saturday with Engulf, rated unlucky on debut behind Movie, nominated to run at Rosehill.
