Tough gelding Lordag regained his desire to win to give trainer Robert Heathcote a treble and owner Neil Owen a double at Doomben.

Heathcote also won with Ingeegoodbe and Manias for 11 wins for the season and second place in the trainers premiership.

Manias and Lordag are owned by syndicates headed by Darling Downs pharmacist Neil Owen who is a long-time breeder.

"Neil has about 20 horses up there on the Downs but I say only send me the good ones. He has done that with Manias and Lordag," Heathcote said.

Lordag had not won for more 18 months and Heathcote was beginning to wonder about the seven-year-old's future.

"I was starting to wonder if he wanted to be a racehorse any more. But we changed a few things and he should have probably won the Ballina Cup last start when he hit the fence in the straight," Heathcote said.

"I once thought he might make a stakes horse but these type of races are probably the best for him."

James Orman also completed double on Lordag as he had earlier won on Manias.

"Jimmy is riding very well and looks to have a very brought future," Heathcote said.

Trainer Stuart Kendrick believes Spring Tycoon ($7.50) could be ready to fulfil his promise after he won the Gadens Lawyers Plate.

"That might be the way to ride him - miss the start and then scrub him along," Kendrick joked.

"The barrier makes the difference here at Doomben and today he had number one.

"But he is a big gross stallion now and he has taken time to get to his best. But he does have a lot of ability."

Impregnable confirmed his rating as Brisbane's most improved horse when he won the VAE Group Class 6 Handicap (1200m).

Stable foreman Trent Edmonds said Impregnable had continued to improve with racing.
