Dan's Dream came with a strong run on the stands side to land the Dubai Duty Free Stakes at Newbury and put herself in contention for a crack at the Qipco 1000 Guineas.
The Mick Channon-trained filly was fit from a victory at Bath three weeks ago and showed she had improved plenty for that outing by springing a surprise in this Group Three contest over seven furlongs, registered as the Fred Darling Stakes.
Heart Power set a decent pace until being swallowed up once the race for the line began in earnest.
Dan's Dream (10-1) was the last to pounce in the hands of Silvestre de Sousa and quickened up nicely to win by a length and a quarter from Tajaanus, with Dance Diva a short head away in third.
Alhough Dan's Dream is not entered in the 1000 Guineas at Newmarket, Channon hopes the owners will agree to stump up the cash at the supplementary stage.
Channon said: "We've thought a lot of her for a long time and we know she's got the class to go back to six furlongs or step up to a mile.
"But it's up to the owners where we go and I hope it's to the Guineas. She's a smashing filly and that race has been a long ambition. We haven't had much luck in it, though.
"Today the plan was to ride her like a good horse and with this filly there could be no excuses. Silvestre said she picked up well and could go either direction distance-wise."
Dan's Dream was given a first show of 16-1 for the 1000 Guineas with Paddy Power.
