The David Payne-trained French Fern had few favours in the run under Blake Shinn being caught three deep without cover the trip.
But the daughter of Lope de Vega is nothing if not game and she struck the front 300 metres from home before easily holding the challenge of Quick Feet (Northern Meteor) by three-quarters of a length with
Honesty Prevails races behind the leader and was momentarily hung up for a run. When the rails opened up she was one paced and struggled into fourth spot.
An all the way winner at Canterbury at her previous start French Fern may not be set for the Golden Slipper according to David Payne.
"We might not go there; we'll see how she stacks up," Payne said.
"We got a few weeks to decide. You don't want to ruin them early, she is a valuable filly we'll let the dust settle and then we will decide.
"She will improve on the run and she got a lot of potential."
Winning rider Blake Shinn suggested the Golden Slipper may be a bridge too far.
"I think she's got to improve a bit to win a Golden Slipper," Shinn said.
"She gives me the impression she might be better suited at 1400m to a mile.
"She did a great job. She was wide the whole way but always travelled well. She kicked strongly and had to grit her teeth to win the race."
Bred by Patinack Farm, French Fern was a $20,000 Magic Millions purchase from the Patinack Farm dispersal and races for a large group of owners including Wilf Mula's Aston Bloodstock.
Payne had purchased the filly's year older brother, Be Like Dad, for $34,000. He finished second at Wyong on Thursday and remains a maiden after 11 starts.
French Fern is the fourth foal and second winner out of the Strategic mare La Famelia who won four of her 16 starts including the Listed Hareeba Stakes.
Her dam Blondine (Danehill) is out of a three-quarter sister to the champion sprinter Schillaci.
Winner of the Group 1 French 2000 Guineas and French Derby in 2010, Lope de Vega (pictured) shuttled to Patinack Farm for four seasons and French Fern is from his second crop.
