Lafferty, who has been riding since September guided the Geoff Withers-trained Unrealistic to victory over Doc Holliday and Jumbo Prince in the $25,000 race.

Her father Peter trained Condies Fair to win the race in 2001 while her grandfather trained the winner on five occasions.

Withers told The Standard he was proud to give the 21-year-old apprentice her first cup victory.

"I'm confident this will not be Laura's last cup winner," the Warrnambool-based trainer said.

"She's a very talented jockey. It was a perfect ride by Laura. She followed my instructions to the letter."

Lafferty said she was confident in the run that Unrealistic was the one to beat.

"I was travelling real well," the former Emmanuel College student said.

"There was a gap at about the 250-metre mark and Unrealistic went through it.

"The race was over after that, he was just too strong for his rivals in the run to the line.

"It was great to win my first cup race for Geoff. He's been friends of my family for years."

Unrealistic's win was the second leg of a treble for Lafferty on the seven-race program.

She won on Woolsthorpe Reign and the last race on Articulator.

The winning treble was her second in her short career.

She booted home three winners at Wodonga on October 19.

Withers said he may back Unrealistic up in a $135,000 handicap at Moonee Valley on Saturday.

"I'll just see how Unrealistic pulls up, if he's alright I might send him around at the Valley," the former Warrnambool Football Club coach said.

"I'll wait until Saturday morning before making a final decision. He's very fit and the 2040 metres at the Valley should suit him."

Six of the seven races on the program were won by female jockeys.
