The stable celebrated a Group One win on Golden Slipper day when Mirjulisa Lass staked her claims for the time-honoured AJC Australian Oaks by brilliantly claiming the $400,000 Vinery Stud Stakes (2000m) at Rosehill.
The three-year-old went into Saturday's race having won two of her four starts this campaign and top jockey Corey Brown, who had ridden her at her past three starts, stuck with her for her first test at the top level.
Brown gave Mirjulisa Lass a unimpeded ride, giving her time to find her feet early then saving valuable ground along the inside when the field fanned rounding the home turn.
Mirjulisa Lass did the rest, looming up on the inside and dashing to the front to put the result beyond doubt in a matter of strides. She established a new class record for her effort.
She had 2-1/2 lengths to spare over Fibrillation at the finish with Crown Oaks winner Brazilian Pulse third.
The Oaks has been Mirjulisa Lass' long-term goal for some time so it was a thrill to see her step up to the plate and win one of the traditional lead-up races to the 2400 metre Classic, run at Randwick on April 16.
Greg said he had been unable to fault Mirjulisa Lass' preparation and he was rapt to claim another career Group One with the filly, which followed his first Group One win with Royal Purler in the 2002 Group One Flight Stakes, also at Randwick.
"It's been a long time since the last one and everything has gone along 110 per cent perfect," Greg said.
Mirjulisa Lass, out of Dolphin Street mare Dol, is raced on lease from Paul Higgins of Baerami Stud which stands the filly's sire Danasinga.
"I got a group of people together after the mare arrived to lease her….Paul said there's one left in the paddock for $2,500, they couldn't sell it and I got it," Greg explained.
"She's a really good chance in the Oaks."
