As anyone travelling down Alison Road in Randwick is aware - Winx is coming.

The Australian Turf Club is displaying banners saying just that ahead of the champion mare's return at Randwick in Saturday's Warwick Stakes.

The highest rated horse in the country is blissfully unaware of the controversy surrounding a minor operation she had months ago which was revealed last week.

Although trainer Chris Waller broke no rules by not publicising she had a bone chip removed, there is now talk of actually changing those rules.

That aside, Winx will have a fast gallop on Tuesday morning in preparation for her first race since the Doncaster Mile.

"Hugh Bowman will ride her on Tuesday morning," Waller said.

"She's pretty right for Saturday and everything has gone smoothly."

Winx has not been beaten since she ran second to Gust Of Wind in last year's Australian Oaks.

Nominations have been extended with Monday's entries at eight, four from the Waller camp.

Grand Marshal, Who Shot Thebarman and Vanbrugh are all likely to join her along with Lucia Valentina, Rebel Dane, Hartnell and Dibayani.

Winx is at $1.45 in the TAB's first market with Lucia Valentina, who is also entered for the Group Three Show County Quality, the $8 second elect.

The Waller-trained Preferment was taken out of the nominations with the Chelmsford Stakes two weeks later his likely goal first-up goal.

"Grand Marshal and Who Shot Thebarman will follow a similar campaign to last year towards the staying races," Waller said.

"Vanbrugh is also entered for the Show County Quality so we will look at what weight he gets in that."

The stable has entered three horses in the Up And Coming Stakes - Cellarman, Nikitas and Pound Sterling.

"I don't think Nikitas will run and maybe only one of the other two," Waller said.

Saturday will be the third week of stakes racing in Sydney this season but the first time the stable has had a Group or Listed runner this term.
