John Gosden's filly was turning out quickly having made a winning debut at Yarmouth only 11 days ago, but despite displaying obvious signs of inexperience, she produced a classy display that earned her a quote of 16/1 with Sky Bet for next season's 1000 Guineas.
Just as was the case at Yarmouth, Indigo Girl (10/3) was taken back early as Dubai Fountain and Lilac Road cut out the early running before Dettori made his move at the halfway stage.
Dettori had nursed Indigo Girl into the lead approaching the final furlong while on the opposite flank, hot-favourite Zabeel Queen made her move as Dubai Fountain battled on gamely in the centre.
Although shifting right and then left once in front, Indigo Girl still had plenty left in the tank when straightened up and past the winning post with a cosy three quarters of a length in hand over Dubai Fountain.
Zabeel Queen could only finish third, just ahead of Lilac Road.
Gosden, who was winning the race for a fifth time, said: “She did it very smoothly at Yarmouth and she’s been in great form since. The race didn’t knock her back a bit – it was rather like a piece of work.
“If we’d gone for another novice race, she would have had to lump a lot of weight and I don’t like doing that with two-year-olds. You can end up giving 7lb to a Group horse and you don’t know it.
“The May Hill is a beautiful race over the straight mile. The track is in beautiful nick and I thought we’d bring her here and see if we could nick a bit of black type.
“She relaxed beautifully, which is key, and smoothly came through. I admit when she hit the front she ran around, but that’s the trainer’s fault because when I work them at home, I don’t like them bursting clear and breaking another one’s heart.
“She’s obviously got a lot of talent. As long as she continues to enjoy her racing,she can move upward.”
Considering future targets, the trainer added: “There are two options this year – the Prix Marcel Boussac and the Fillies’ Mile. We could look at either of those or wait until next year, we’ll just have to see at this stage.
“Her mother (Montare) won a Prix Royal-Oak and her full-sister (Journey) won the Fillies & Mares Stakes on Champions Day at Ascot over a mile and a half. Funnily enough, I see this one as more of a mile to a mile-and-a-quarter filly.
“She travels strong and has a great turn of foot.”
Dettori added: “I rode Journey (her sister) and she’s the same type – not over-big, but she’s got loads of gears. It’s my first time on her.
“She travelled smoothly, quickened well, ran a bit green and went left and right, but it’s only her second start so you can excuse her for that.
“She’s from a talented family. Everything is in the right place and I really like her.
“She seems easier to handle than her siblings. She’s got a good future and is two from two and a Group Two (winner). Fingers crossed she can go all the way.”
