Dracarys has reinforced her standing as the filly to beat in next month's WA Oaks, following an effortless win in the Oaks Prelude (2130m) at Gloucester Park.
It was another impressive display from the Justin Prentice-trained filly, who scored by 5.8m to Soho Interceptor.
Reinsman Gary Hall Jnr slowly made his way to the front on the Bettors Delight filly from barrier 12 and was then too strong over the closing stages, where she ran home in 56.6.
Fake News, who won the Oaks Prelude last week, finished third.
Balcatherine, the second favourite in tonight's event, was unplaced after having to go back from the wide draw.
Hall Jnr said it was a professional performance by Dracarys.
"She's got good speed," he told RWWA Harness.
"I always planned to put her into it tonight when the pace allowed us to.
"She's got a motor to go with it too."
Hall Jnr said he expected the filly to improve further for the Oaks and was full of praise for Prentice's training performance.
"Justin has always been good at getting them to peak at the right time," he said.
"This has always been the plan for her and her main aim this prep.
"He's pretty good at what he does, so I just leave that up to him."
Prentice then teamed up with reinsman Dylan Egerton-Green in the later in the night with fellow three-year-old Back In Twenty to take out the Glenroy Chaff Pace (2130m).
A smart field of three-year-old colts and geldings assembled for the event, but a smart Egerton-Green drive was enough for the colt to score a comfortable win to Sangue Reale.
Elsewhere on the Gloucester Park meeting, Mighty Conqueror took out a thrilling edition of the Group 2 Easter Cup (2902m).
Mighty Conqueror eventually worked to the front after starting off a 20m Handicap, but had to hold off a fast-finishing As Happy As Larry.
Reinsman Ryan Warwick declared post-race the four-year-old had the potential to be a key in feature races over the summer carnival.
In the Free-For-All event of the evening, Vultan Tin showed his trademark toughness to score a narrow win over Always Arjay.
Vultan Tin settled in the breeze for reinsman Chris Voak, as Always Arjay led from the inside barrier.
The tough gelding loomed on the home turn and looked poised to score an easy win, but Always Arjay fought back on the inside to make it a tight finish.
It was the second leg of a driving double for Voak, who scored on Back To The Beach earlier in the evening.
