Commissioning was introduced into next year's 1000 Guineas betting at 20/1 following a taking debut success in the Turners British EBF Fillies' Novice Stakes at Newmarket.
Trained by John and Thady Gosden, the daughter of Kingman sprinted clear of some choicely bred rivals to win by three and a half lengths.
Ridden confidently by Frankie Dettori, the 13/2 winner hails from the family of Irish Derby and St Leger winner Capri, so it bodes well she displayed so much pace to win over seven furlongs.

Dettori admitted to being taken aback by the performance and said: "She has done it nicely and has taken me by surprise a bit but they told me that she was okay this morning.
"She was a bit green early doors but I gave her a little flick and she got down and started racing and she finished the race very strong. I hadn't sat on her at home before this.
"Sheikh Isa (joint-owner) is a good friend of mine and he text me from America and wished me all the best so I'm sure he will be happy now.
"I think seven (furlongs) is fine for the moment but she will probably end up going up to a mile before the end of the season."
Emotion had her supporters smiling as she led home a Qatar Racing one-two in the British Stallion Studs EBF Chalice Stakes at Newmarket.
The daughter of Frankel, trained by the Gosdens, was well held in the Queen's Vase at Royal Ascot on her most recent start, but was always in the perfect position in the hands of Andrea Atzeni back down in Listed company.
Sent off at 13/2, Emotion shadowed the favourite Rose Of Kildare, who took the field along in the hands of Cieren Fallon.
Fallon looked to have got the fractions right when Atzeni on Emotion and Rossa Ryan aboard the eventual third Star Fortress started to pump away on their mounts, but the Clarehaven filly found plenty for pressure and having took the lead close home, was a length clear of the runner-up at the line.
