David Hayes is hoping the predicted rain stays away from Flemington for the sake of his VRC Oaks favourite Sacred Eye.

With internationally renowned jockey Ryan Moore in the saddle, Sacred Eye has been marked at $3.50 for the 2500m fillies classic on a track currently rated as good.

Hayes fears a significant downgrade in the track condition could thwart his filly's chances.

"We're hoping there's not a lot of rain because if it's a wet track it might sway the advantage the way of the other fillies," Hayes said.

Sacred Eye is coming off a win against the males in the Caulfield Classic over 2000m on October 17, bypassing the traditional fillies lead-up races including last Saturday's Wakeful Stakes at Flemington.

Hayes is confident that will prove a winning move, providing the rain doesn't arrive.

"She's had a fantastic build-up," Hayes said.

"We deliberately didn't run in the Wakeful and I think that will pay dividends in the long-term.

"Those fillies will be lining up for their third run in three weeks, whereas it will be just the second for mine."

Hayes said the daughter of High Chaparral had been trained from Lindsay Park's Flemington stable as he didn't want to change a winning formula.

She will spell at their Euroa operation after Thursday's race and return for an autumn campaign.

And longer-term Hayes thinks Sacred Eye could be a contender for some of the bigger spring races in 12 months.

"She's grown on us all prep but we really feel she's going to have a big autumn and then maybe in the good races next year," Hayes said.

"That's how much I think of her, I'm very keen on her."

With Sacred Eye holding top spot in the betting, recent Moonee Valley winner Jameka and last Saturday's Wakeful winner Ambience look the stiffest opposition and share the second line of betting at $4.
