The regally-bred Sun Maiden was halved in price to 20/1 for the Investec Oaks by Sky Bet after routing her rivals in division one of the Smith & Williamson Fillies' Novice Stakes at Salisbury.
A Frankel half-sister to Midday, she was fourth on her only start at two but was the best backed horse of the day on her reappearance.
The money looked safe throughout the contest as she chased the early pace before going to the front with two furlongs to run.
There were understandable signs of greeness as she went clear of the chasing pack but she hit the line hard under Pat Dobbs and was 12 lengths clear of her nearest pursuers White Light and Whispering Sands at the line.
She holds an entry in the Epsom Classic as well as the Ribblesdale at Royal Ascot and is a filly well worth adding to your My Stable tracker.
"She was very green on her debut and she was still pretty green today - at one stage she jumped a leaf or something," said Teddy Grimthorpe, racing manager to owner Khalid Abdullah.
"Obviously we couldn't be happier with how she did it, and she has a really nice stride on her."
The sky could be the limit for Sun Maiden, with the English or Irish Oaks possible targets down the line, as well as Royal Ascot.
"All options are possible at this stage, but in an ideal world you'd love to get another run into her before the Oaks," said Grimthorpe.
"I'd need to talk to Sir Michael before we get too carried away as it was only a novice race.
"She could go the Ribblesdale-Irish Oaks route. We'll have to see how she comes out of this and see what Prince Khalid wants to do."
