Bart Cummings unveiled another potential top-class filly at Canterbury on Wednesday when Ardeche scored an impressive debut win.

The well-bred two-year-old came from a long way back in the field to take out the STC Members Plate (1100m) by a length over Rock Haven with Light Warrior a long head away third.

Although the race was only an off-season midweek maiden for two-year-olds, stable foreman James Cummings said connections had high hopes for the daughter of Dehere out of Danehill mare Diamond Like.

"She's pretty good," Cummings said.

"She's well bred and I think she's going to race right up to her breeding and go on with it from here."

Ardeche's half-brother by Zabeel sold for $2 million at the Karaka yearling sales in New Zealand earlier this year.

The filly's mother Diamond Like was a stakeswinner and Group One-placed in New Zealand and is a sister to Group One winner Viking Ruler as well as other stakes performers including Kempinsky.

Cummings said the later stages of the Brisbane winter carnival were an option with Ardeche.

"We'll just wait and see how she pulls up and see what Bart plans for her," Cummings said.

"She's got a little bit of growing to do but there's plenty of quality about her and we've got no doubts she can reach some pretty high limits."

Jockey Blake Shinn had been on the filly's back twice in barrier trials leading into the debut and had a feeling Ardeche was pretty smart.

Shinn elected to drift back from an awkward barrier but was confident in the way the filly was travelling with good speed on up front.

He pulled the youngster to the extreme outside before the turn and said she tracked into the race like the winner.

"She was very green in the straight and tried to throw it away a bit but I think her class shone through in the end," Shinn said.

Warwick Farm trainer Marc Conners got the best result possible from his two runners on the day with both Miss Shamardal and Letchworth handling the heavy conditions to both win.

Three-year-old Miss Shamardal took out the Rosehill Event Centre Handicap (1580m) while Letchworth proved too good in the Winning Post Restaurant Handicap (1580m).

"I came here with two good chances and with the first filly (Miss Shamardal) we were just hoping she would get through the wet," Conners said.

"Letchworth, on the other hand, loves the wet and it showed today."
