Connections of exciting Darci Brahma filly Sierra Sue are hoping the New Zealand-bred three-year-old can continue her near perfect formline when she contests the Gr.1 Australasian Oaks (2000m) at Morphettville on Saturday.

The Trent Busuttin and Natalie Young-trained filly has won three of her four career starts, with her only blemish coming when she finished runner-up over 1600m two starts back.

Part-owner John O’Neil has been thrilled with her performances and he is enjoying the experience of being involved with the Busuttin-Young stable.

“It has been a short relationship, but a really positive one, and one we are building on pretty quickly with Trent and Natalie,” O’Neil said.

“They are great communicators and wonderful trainers. Trent bought this horse off a trial with Ozzie Kheir. So all the boys who are in Ozzie’s crew jumped into this.

“We are really excited to win three starts out of four in the first prep.”

O’Neil is buoyed by Busuttin’s confidence heading into Saturday and said it isn’t too dissimilar to when stablemate Tagaloa won the Gr.1 Blue Diamond Stakes (1200m).

“Trent has always had a big rap on the horse. I know she has worked really well and he seems really happy with the horse,” O’Neil said.

“I know Trent is pretty confident and the last time he was this confident was when he was talking to me about Tagaloa prior to the Blue Diamond.”

Sierra Sue has drawn the outside barrier in the 16 horse field, but O’Neil said the track conditions on Saturday will dictate the virtues of the draw.

“We have drawn the car park,” he said. “We will just see the way the track is playing. There will be a fair amount of rain and I will imagine she will get through that okay.

“Whether we go forward or back will depend on the pace in the race.

“Let’s keep our fingers crossed and hope she runs well.”
