Co-trainer Simon Zahra has admitted to an attack of nerves on the eve of the return of Golden Slipper Stakes winner Crystal Lily in the Listed Quezette Stakes at Caulfield.

The star filly has impressed the stable in her jumpouts leading up to Saturday's 1100m feature but Zahra, who trains the filly with Mathew Ellerton, said they were feeling the pressure.

"It is a bit of a nervous time but we are keen to get her underway," Zahra said.

He said expectations were high that Crystal Lily would start her spring the way she left the autumn and that she would most probably follow a traditional path towards the Group One Thousand Guineas (1600m) in October.

"She's had two trials and they have been terrific," Zahra said.

"She has run good time and she has done it pretty easily.

"It is not ideal to start her off on a heavy track but she has got to start somewhere and we are looking forward to it."

The winner of four of her seven starts, Crystal Lily is a pronounced favourite at $2.20 with TAB Sportsbet to bring up her fourth win in a row.

Shaaheq ($6.50), She's Got Gears ($7.50) and Broadway Harmony ($8.50) are the only other runners under double-figure odds.

Zahra said Crystal Lily had been one of the toughest two-year-olds he had been associated with but was mindful that not all Slipper winners train on.

"Sometimes they don't come up and sometimes they turn out better than you think," Zahra said.

"We will just take it one step at a time.

"We haven't really got right into her because the tracks have been so wet but she has impressed us.

"She has come back more relaxed and has matured mentally."

Crystal Lily's return to racing coincides with the first-up appearance of Blue Diamond Stakes winner Star Witness who has been sensationally backed from $4.80 to $3.30 favouritism in the Listed Vain Stakes (1100m).

The Robert Smerdon-trained Breitling opened equal favourite with Star Witness but it was no surprise to his jockey Glen Boss to see him drift in the market to $6 on Friday.

"He is a very nice horse but he has got to take a massive step on Saturday," Boss said.

"There is a huge boom on him but you have got to keep it in perspective.

"He got beaten first-up in a winter two-year-old race and then won one after getting a beautiful run the other day one-out, one-back.

"They had him short in the market for Saturday which shocked me but until they prove it against better horses they are a bit of an unknown."
