Last seen in the Superlative Stakes in July, Appleby had said all along that this seven-furlong event would be his next race.
He faced stiff opposition in the shape of Aidan O’Brien’s Anthony Van Dyck, winner of three of his four races before this, but Quorto was still sent off the 11-8 favourite.
The son of Dubawi travelled much sweeter than the Ballydoyle runner and William Buick cruised into the lead with Ryan Moore hard at work.
While Anthony Van Dyck did stick to his task gamely, Quorto was always holding him at bay and although the stewards did look into the fact he drifted towards the runner-up, the placings unsurprisingly remained unaltered.
Appleby said; “He’s come here with a lovely profile having won his maiden over six and then stepped up to win the Superlative Stakes over seven furlongs last time.
"He needed all the time he had between the Superlative and this race as he went a bit quiet in himself but in the last ten days or so he has come back to where he was before the Superlative and we came here confident.
“He’s put himself there as a candidate for the 2,000 Guineas and at this stage if you pinned me down I’d say he’s a miler who could stretch out to ten furlongs.
"He’s very much his father in many respects and he’s the first Group 1-winning two-year-old colt by Dubawi so if we now put him away for the winter so be it.
“Obviously if he does run again this year it will be in the Dewhurst Stakes but we’ll see how he comes out of this and I’ll speak to his Highness Sheikh Mohammed and then we will make a decision on whether he runs again this year.
"He’s probably learnt a lot more today than he did in his first two races and mentally he’ll come on a good deal from today.”
