Trainer Bryan Dais knew six months ago that Rannoch Moor was the best horse in his stable.

Wanting to ensure Rannoch Moor was physically and mentally ready to race for the first time, Dais waited until Wednesday at Eagle Farm to unveil the colt.

The three-year-old defied a betting drift from $5.50 to $10 to win The Good Guys Maiden Plate (1200m) by half a length.

"He's the best horse I've had step into my stables," Dais said.

"Everything about him is perfect. He's a beautiful type with a good pedigree and a good attitude."

Dais paid $25,000 for Rannoch Moor at last year's Magic Millions Breeze-Up sale and the horse was named by part-owner Nick Anderson after an area of land in the Scottish highlands.

"I told the owners six months ago that he was a very good horse and they were good enough to allow me to give him the time he needed to mature," Dais said.

"We could've raced him during the winter but we decided to be patient which is why we turned him out after he trialled."

Jockey Larry Cassidy was impressed by Rannoch Moor and believed the Snippetson colt would improve immensely with more experience.

"He's an impressive type to look at but he's still learning," he said.

"Every trial that I've ridden him in he's missed the start because when the gates open he panics.

"He did it again today but he jumped away better and I said to the connections `don't worry because he's not a jump and run type anyway'."

Dais won't rush Rannoch Moor this campaign and is confident the colt will win races over 1600m in the future.

Earlier, trainer Steve O'Dea praised apprentice Aidan Holt for his cool ride on Pasquinel who won the Novotel Brisbane Airport Plate (1500m).

"Another horse laid on him in the straight but Aidan didn't panic and just kept him balanced," O'Dea said.

"Since Aidan's started riding in town he's really put it together and his weight is good so he should have a really good season."
