Sydney trainer Gerald Ryan is confident that Mrs Onassis can have a successful Melbourne Spring Racing Carnival – as long as the wet weather stays away.

The Group 1 winner has recorded all eight off her career wins on good or dead tracks and has struggled significantly in the wet with a third place finish at Wyong in 2011 her best performance on a slow or heavy track, so it is no surprise that Ryan is concerned about the notoriously difficult to predict Melbourne weather.

Mrs Onassis will resume in the Listed John Monash Stakes (1100m) at Caulfield on Saturday, which Ryan is hopeful will be the beginning of a successful campaign.

”It’s a nice race for her on Saturday, in fact there could be a couple of races in Melbourne that will suit her, but it just has to stay dry for her to remain down there,” Ryan told Fairfax.

“She’s OK up to dead, but from then on she struggles.”

Ryan said the General Nediym five-year-old could not be in better condition for what is expected to be her last preparation before retirement.

”I really could not be happier with her, her work and trials have been very good,” the leading trainer said.

“Her last little bit of work on Tuesday morning was just what I wanted, so we put her on a float for Melbourne and hope she can win again at Caulfield.”

Mrs Onassis is returning to Melbourne for the first time since her surprise victory in the Group 1 Oakleigh Plate (1100m) at Caulfield in February.

She has an excellent record at the track, having previously run third in the Group 3 Sportingbet Sprint (1200m) and won the Listed Alinghi Stakes (1100m) at the home of the Melbourne Racing Club.
