Smart mare Doubtfilly begins a new phase of her career with Danny O'Brien this Saturday in the $100,000 All Victorian Sprint Series Heat 4 (1100m) at Flemington.
The four-year-old daughter of Not A Single Doubt had been trained by Stuart Kendrick and done her racing in Queensland prior to being purchased by Blue Sky Bloodstock for stable clients of O'Brien for $300,000 at the recent Magic Millions National Sale on the Gold Coast.
At her last start Doubtfilly was only beaten three-lengths when unplaced behind Sacred Star and Masthead in the Group III QTC Cup (1300m) at Eagle Farm.
"She's only been with us for 10 days and she arrived in good shape," O'Brien said. "I can't see why she wouldn't run well Saturday .
"We've kept things pretty simple with her, she seems to adjusted well to her new surroundings. She went nicely here on Tuesday so she's good to go."
If the forecast rain does arrive and Flemington becomes rain affected then her chances would be enhanced if past performances are an accurate guide.
Doubtfilly is unbeaten in three starts on dead ground and has won two of her three starts on heavy tracks, a statistic that has not gone unnoticed by her new trainer.
"If we got any sort of rain, certainly that will help and I'd expect her to improve the softer it gets," O'Brien said.
