There has been a boil over in the Vinery Stud Stakes, with Mirjulisa Lass taking out the fourth race on Golden Slipper day.

Mirjulisa Lass was a $51.00 outsider going into the race, and beat home Fibrillation and race favourite Brazilian Pulse.

Trainer Gregory Hickman was elated with the win and confirmed the Danasinga filly would line up in the Oaks.

“She did probably have a fitness edge on some of these but I can’t believe it,” said Hickman.

“She was 110% fit going into this and now she is a real chance in the Oaks,” continued Hickman.

Jockey Corey Brown was always confident in the horse as it was revealed he rated the 50-1 shot as his best ride of the day at a mid-week function.

Fibrillation, ridden by Damien Oliver for Tim Martin battled bravely for second while race favourite Brazlian Pulse finished third for Mike Moroney and Craig Williams.

Brazilian Pulse was posted three wide for the entire trip and lacked the necessary zip to go with them at the end.

Meanwhile Pinker Pinker was fourth in what looked like a nice Oaks trial.

The Peter Moody trained Do Ra Mi was heavily backed in the final stages of betting, however it now appears she is more suited to the shorter trip. She had a nice run in transit but found the final furlong of the 2000m trip too testing.

Murjulisa Lass snuck up along the fence going into the home straight and produced a powerful burst to shoot clear of the field. No one looked like catching her after that.
