Trainer Simon Miller issued an ominous warning after landing his fourth Supremacy Stakes (1000m) victory in the past six years with Seannie at Ascot on Saturday.

“She is all quality and is only going to get better as she goes further,” Miller said.

“If she was going to be vulnerable it was going to be in this race.

“But I still thought she would come and put them away which she did.”

Seannie’s dominant performance to defy a leaders bias has seen her surge into Karrakatta Plate favouritism, her quote slashed from $8 into $3.50.

The Sebring filly was slow out and settled near last, but once jockey Aaron Mitchell hooked her to the outside she exploding with a blistering finish.

“”I’m so proud of Aaron who is an apprentice to us and I’ve always wanted to reward him with a really good ride,” Miller said.

“He has done the hard work over the years and it is nice to see him have the opportunity with a horse like this.

“No doubt it was exciting for him as it was for me.”

Seannie maintained her unbeaten status after defeating Golden Trigger when on debut at Ascot last October.

Miller said he would let the dust settle before mapping out Seannie’s next start ahead of the Karrakatta Plate in April.

“I will see what this run does , but the logical path is the Gimcrack,” Miller said.

“But we are in the box seat with her so we can do what we need to do.

“We will let her tell us, but Karrakatta Plate here we come.”

Grant and Alana Williams had strong representation in the Listed Ascot 1000 Guineas (1800m) with five runners including favourite, Royal Star, but it was Awaken who emerged victorious.

Ridden by Peter Hall, the daughter of Dream Ahead ran through the line strongly, propelling her to the top of the market for the WA Oaks (2400m).

And Material Man ended a lean Ascot drought for trainer Justin Warwick with an impressive performance in the last race on the card.

Giving Hall the second leg of a double, Material Man covered ground when wide throughout, but finished better than any other runner.

Warwick said the son of Vital Equine, who defeated Point by two lengths with Terror Force third, could back up in the Bunbury AHA Cup (2000m).
