Chris Waller was hailed as a genius but modesty kept the Sydney trainer from accepting the credit for Winx making a one-act affair of the Queensland Oaks at Doomben on Saturday.

Instead, Waller said Winx should be admired for her resilience as well as her obvious brilliance over a distance.

Winx raced through the Sydney autumn carnival but there was no evidence a long campaign had taken its toll as she strolled clear for a 3-1/2 length victory over 2200m that gave Waller his 13th Group One success for the season.

The filly is raced by a syndicate headed by Brisbane businessman Peter Tighe and his wife Patti who have long wanted to win a Group One race in their home town.

"Chris is a genius. To get a filly to win an Oaks on one lead-up run shows how good a trainer he is," Tighe said.

Winx ran second on a wet track in the ATC Australian Oaks last month and she emerged as the horse to beat on Saturday with a last-to-first win in the Sunshine Coast Guineas.

Waller said having Winx ready to peak for the second time in a preparation had more to do with the filly than his training methods.

"I don't look at it that way with good horses. After she ran second in the Australian Oaks, I sat down with my staff and said it was going to be hard to make Brisbane," Waller said.

"But we did it and a quality filly like her just needs to be kept fit without being flattened."

Sent out favourite, Winx ($1.90) stormed home to beat Ungrateful Ellen ($12) with a half length to Imperial Lass ($51) in third place.

Waller said Winx would not press on to the Queensland Derby next week but she would go for a spell with the spring carnival in mind.

"She has been up since the start of the season and owes us nothing. To run in the Derby would add nothing to her value," he said.

"I think she will make a very good 1600-metre horse later in her career and the (Group One) Myer Classic during the spring should be ideal for her."

Winning jockey Hugh Bowman said he could have settled closer on Winx but she was comfortable racing back in the field.

"She has a real turn of foot. I think there is a genuine upside to her as well," Bowman said.

Craig Williams, who rode Ungrateful Ellen, said the filly ran home well but the winner was in a different class.

"But she has been black-type placed now so that is a plus," he said.

Blake Shinn, who rode Imperial Lass, said he had tried to get a break on the field on the home turn but Winx was too strong.
