Trainer Steve Tregea has had reason to celebrate at Doomben despite Rhyming failing to get the stewards' nod in a protest at Doomben.

Rhyming's jockey Ryan Wiggins protested against Robbie Fradd on the winner Cushion Pink after going down by a half head in a 3YO Maiden (1110m) on Wednesday.

Wiggins alleged Fradd took his mount in towards the fence in the final 200m and cost him at least a neck but stewards quickly dismissed the protest.

Tregea left to saddle his runner in the next race, Mymancharles, who promptly landed a $10 to $4.60 plunge in the second division of the three-year-old maiden.

"It would have been nice to get the protest but Mymancharles beat Rhyming by five lengths in a jump-out last week so it gave me a good guide of what to expect," Tregea said.

The trainer breeds most of the horses in his stable and sent his mare Aloha Charm to Myboycharlie with the result Mymancharles.

"Aloha Charm is a big mare by Marauding and I got her off the legendary (owner-breeder) Jim Fleming. She is a sister to the stakes mare Pontal Lass and her first foal sold very well but she hasn't had much since," Tregea said.

"In fact I gave her to a friend of mine and he has got her in foal to Spirit of Boom."

Cushion Pink's win continued trainer Robert Heathcote's uncanny ability with the offspring of sire Mossman.

"I don't keep those types of records but it would be more than 50 winners I have trained by Mossman," Heathcote said.

"After all Buffering and Hopfgarten are by Mossman and have won 30 races between them."

Toowoomba trainer Ben Currie also stuck to a winning formula when former Victorian Kuznetsova won at her first Queensland start.

Currie has had a lot of success with Victorian cast-offs with the most notable being Toowoomba Cup winner Honey Toast, who recently returned to work.

"Kuznetsova was with Mick Price and my cousin who works for Mick has a share in her," Currie said.

"When Mick wanted to move her on, he decided to send her to me."
