Doubtfilly had promised her connections a black-type victory ever since winning four juvenile races during Queensland’s 2011-12 summer carnival.

It took 18 months but the Not A Single Doubt filly finally fulfilled that potential in the LR Ascot Hcp (1200m) at Eagle Farm on Saturday.

Doubtfilly (3f Not A Single Doubt – Aussie Enchantee by Alhaarth) did it in typically game fashion, peeling out in the straight, putting her head down and delivering her best effort to win by a short neck from Griffon (Flying Spur).

Trainer Stuart Kendrick indicated Doubtfilly would be aimed at the Queensland Magic Millions instead of a Melbourne spring campaign.  “She’s finished fourth in a Golden Slipper and third in the Gai Waterhouse Classic but winning today puts that extra bit of value on her,” he said.

“Things haven’t really gone her way this carnival but I always thought this race would be a good option for her before she goes to the paddock.”

Doubtfilly was a $17,500 buy at the 2011 Gold Coast Magic Millions and is raced by Kendrick’s wife Trudy along with fellow owners Paul & Lyn Maguire, Andrew & Hayley Wheeler, Chris & Elizabeth Cook, Russ Collins and Paul Ingerman.

She is the 17th individual stakes winner for Not A Single Doubt and Saturday’s victory increased her earnings to $630,000.

Doubtfilly is the first foal of Aussie Enchantee, a winning daughter of the French G2 winner Andromaque (Woodman).who was imported by Bob and Rosemary Scarborough’s Wood Nook Farm in 2002.

It’s been a milestone season for Not A Single Doubt following his stunning G1 Blue Diamond Stakes winner Miracles of Life.  Arrowfield Stud stands him for a $33,000 (inc gst) fee.
