Trainer Kuah Cheng Tee put Decreto's debut win down to raw ability, but said better things should be in the offing after he noticed a sharp improvement in his mannerisms since.

The Red Giant three-year-old, who was sold from Westbury Stud's 2015 NZB Festival draft, was very wayward at his first start on February 3, hanging out and not really toeing the line for experienced jockey Azhar Ismail throughout the Restricted Maiden race over 1100m.

But the moment the winning post caught his eye, he sprouted wings to score quite comfortably.

The rough-hewn run was cause for concern, but Kuah reported that Decreto has mended his ways since. Condition-wise, he has not gone backwards, fuelling Kuah's hopes he will do equally well, if not better at his next start in Friday's Class 4 race over 1200m on Polytrack.

"He's calmed down a lot, he's more settled down now," said the second-year trainer.

"I know it's only his second run coming up but he gives me the impression he has matured so much in that time since his first run.

"Azhar gallops him and has given me positive feedback, too. He trialled him last week and he was very happy with his run (second to Good Lucky).

"He has maintained his condition, but that trial has helped him come on further for Friday's race."

The only question mark bothering Kuah a shade is the rise in class for the Synthetic Stable-owned galloper, but otherwise, he is looking forward to further improvement – both physically and mentally in the race.

"The only query is he will be up in class – Class 4 is much stronger," said the former jockey.

"He is also up in distance but looking at the way he won at his first race, I think he will handle it. We took a chance with him, and let's hope he can win again."
