Debonairly's dominant debut win has given trainers Gai Waterhouse and Adrian Bott another piece of the emerging Magic Millions Classic.

With a racing style synonymous with the stable, Debonairly led all the way to win Wednesday's two-year-old maiden (1100m) at Warwick Farm by 4-1/4 lengths.

Despite drifting to $4 while runner-up Te Amo was tried into $2 favouritism, Debonairly was far too good.

The Michael Freedman-trained third-placed Membership ($2.80) was a further 4-1/4 lengths behind Te Amo.

"She's got Gold Coast filly stamped all over her," Waterhouse and Bott's racing manager Emma Pearce said.

"Just the way she jumped, went to the front and didn't get caught.

"I'd like to see that early January."

After her victory, Debonairly was slashed from $26 to $11 for the Magic Millions Classic.

If she could win at the Gold Coast on January 14, it would be Waterhouse's fourth success in the rich sales-restricted race and her first since Driefontein in 2012.

Jockey Kerrin McEvoy rode Debonairly to win a barrier trial at Warwick Farm on December 2, but said she gave him a different feeling on race day.

"She was on song today and ready to pump," McEvoy said.

Debonairly is the first Australian horse raced by Texan businessmen Peter Flour and KC Weiner and their Speedway Stables LLC operation.

"We're really excited to have a really special filly for them," Pearce said
