A clever race plan helped former Sydney mare Buon Auspicio overcome the odds with her win at Eagle Farm on Wednesday.

Trainer Bryan Guy and apprentice Janette Johnson believed there would be no early pace in the Goulburn Valley Handicap (1400m) and elected to take Buon Auspicio to the lead.

Johnson was able to walk Buon Auspicio through the first 800m and sprint home the last 600m in 33.7 seconds.

Buon Auspicio had won her previous start in a maiden and was skipping classes to tackle Wednesday's race. "It just goes to show you can't beat the clock," Guy said.

"Even top-class horses have trouble getting under 33.7 for their final sectional at Eagle Farm, so they were never going to beat her."

"But it was a good effort because it is near impossible for a maiden winner to win a Class 3 at her next start in Brisbane."

Buon Auspicio is owned by Kate Nivison who sent the mare north from Sydney to replace her black-type placed galloper Jacquetta who has been retired.

It has proved a profitable move for Nivison as Buon Auspicio has now picked up more than $30,000 in prize money.

Meanwhile, trainer Mark Webb continued his good run with the offspring of sire Wicked Style when Fashion App ($8) won the Brisbane Marriott Handicap (1000m).

"We have won three races at Eagle Farm in the past month with the Wicked Style breed," Webb said.

"I have said all along they would be late season two-year-olds and then top three-year-olds."

Wicked Style stands at Oaklands Stud on the Darling Downs and his oldest progeny are three-year-olds.
