The 100-1 outsider Lasqueti Spirit has run her rivals ragged to claim a shock victory in the $1 million Victoria Oaks (2500m) at Flemington.

Jockey Brenton Avdulla adopted daring front-running tactics and set a breakneck speed, with the short-priced favourite Yankee Rose at one stage over 30 lengths off the pace.

And Lasqueti Spirit kept up the ruthless gallop into the straight as her challengers floundered, winning by 3-3/4 lengths from Harlow Gold ($7) and Eleonora ($9) in third.

“I’m speechless,” said Avdulla, who stood in the saddle and took a bow as he crossed the line.

“We thought realistically we could run well without winning … I was riding a good clip here and if I could go on with it and get her flowing that would be my best chance.”

It was the first victory in 10 career starts for Lasqueti Spirit, who finished fourth in a Kembla Grange class 1 race over 2400 metres last month.

“She has one speed. We hatched out a plan with Brenton and the owners and the manager,” said winning trainer Lee Curtis.

“She should have got beat a furlong. She is tough at home but she hasn’t got class but she has a turn of foot. She is a one-batter and she loves it.

“I can’t believe it. I’ll be shaking for a day or two.”

There were no excuses for the beaten brigade, with Damien Oliver (Eleonora) and Hugh Bowman (Missrock, fifth) both reporting their fillies had been found wanting at the end of the strong 2500-metre test.

Yankee Rose ($1.95), who last start finished third to Winx and Hartnell in the Cox Plate, finished 14th, beaten more than 20 lengths.

Her jockey Blake Shinn said he believed the filly’s run against the older horses at Moonee Valley had left her flat.
