Nobody wanted to buy her and she was a rank outsider in the Vinery Stud Stakes at Rosehill but Mirjulisa Lass continued to prove her doubters wrong with a stunning Group One upset on Saturday.

"She was passed in for $2500 as a yearling and a group of first-time owners decided to lease her," trainer Greg Hickman said after the filly's victory at $51.

Ridden by Corey Brown, Mirjulisa Lass trounced a host of AJC Australian Oaks contenders with a burst of speed that belied her starting price.

"Her best asset is that she relaxes well and she's got a really good turn of foot at the end of her races," Brown said.

That acceleration was evident as Mirjulisa Lass raced away from her chasers to score a 2-1/2 length win over Fibrillation ($19) with the favourite Brazilian Pulse ($2.35) three-quarters of a length away third.

The win gave Warwick Farm-based Hickman only his second Group One success after Royal Purler won the 2002 Flight Stakes.

"It's been a long time since the last one but winning for a new group of owners makes it all worthwhile," Hickman said.

"Everything has gone 110 per cent this preparation, she's been perfect all the way through.

"She's got a real good chance in the Oaks now."

In a genuinely-run race, Mirjulisa Lass was hidden away three back on the rails and received a saloon passage when the field fanned into the straight.

She burst through to set up an unassailable lead over Fibrillation and Brazilian Pulse, the VRC Oaks winner who was trying to rally after a torrid run.

Brazilian Pulse was posted three-wide on the speed and lost no caste from an Australian Oaks perspective.

"I just tried to ride the perfect race but they kicked up inside me and I couldn't get in," jockey Craig Williams said.

Trainer Mike Moroney described Brazilian Pulse's run as "very brave" and said there was no reason not to continue on with her autumn campaign.

"We'll still press on to the Oaks," he said.

The Tim Martin-trained Fibrillation is also on target for the $550,000 AJC Australian Oaks (2400m) at Randwick on April 16.

"As long as there is soft ground on Oaks day she will be right in the race," he said.

Leading Melbourne trainer Peter Moody will leave the Oaks on the autumn agenda for Do Ra Mi despite her fifth placing.

"I'll send her back to Melbourne and see how she comes through the run before committing her to a start," Moody said.
