A son of Champion Stakes winner Farhh, he was well backed at Goodwood and the confidence was not misplaced.
He faces 10 rivals in the Group Three, which Johnston previously won with Elliots World in 2004.
Charlie Johnston, assistant to his father, said: "We've seen the final declarations and it looks a race full of horses like him - maiden and novice winners who are stepping up in grade.
"This was the plan for him straight away after his impressive win at Goodwood.
"He is a colt we have always thought a bit of and we wanted to save him for Glorious Goodwood.
"We have been happy with him since that win and hopefully he's good enough."
Aidan O'Brien has surprisingly not won the seven-furlong race since 2000 with Hemingway.
This year he is represented by Fleet Review, winner of his last two races at the Curragh.
The Ballydoyle handler said: "We always thought that he might get further than six furlongs. He is a forward-going horse.
"We think it's a good time and a good track to just start going a little bit further and have another look at him."
Lansky, Wells Farhh Go and James Garfield are others with claims in an open race.
