The Jim Bolger-trained son of his Derby winner New Approach was one of the first off the bridle in the six-furlong heat, but stayed on strongly to run out a decisive winner in the end.
Kevin Manning was sending out distress signals from an early stage on the 7-2 chance, who was stretching his unbeaten record to four.
Stablemate Leitir Mor led until just outside the distance but Dawn Approach was beginning to make headway, along with Aidan O’Brien’s Cristoforo Colombo.
However, it was Bolger’s colt who stayed on strongest to win by three-quarters of a length from 20-1 shot Olympic Glory, who flew from the rear.
Cristoforo Colombo was third with Sir Prancealot, sent off the 3-1 favourite, fourth.
Bolger said: “He’s as good as I’ve had. “He has everything. He has pace, he has stamina, he has looks and he has the temperament. There are no holes in this fellow.
“I don’t see him going beyond a mile and I don’t want him to go beyond a mile. That will do me.
“I’ll probably give him a little break. He’s a very gross horse who grubs (eats) very well, so the break won’t get to be too long.
“I’d say the Futurity Stakes and the National Stakes (are options) and if I can find a space for him in the Dewhurst with the other two-year-olds I have, then maybe the Dewhurst.
“There is always Longchamp as well. He’ll have three more runs (this year) I hope.”
Manning said: “I think he’s probably as smart a two-year-old as I’ve ridden. He’s got the right attitude (for the Guineas), he’s got a great cruising gear and he’s got a turn of foot. The ground is not a huge issue and he ticks all the boxes.”
Jockey Zac Purton got one up for the Aussies ahead of Black Caviar’s appearance on Saturday when guiding Hong Kong’s Little Bridge to victory in the first of Ascot’s speed tests.
The 29-year-old had not ridden in Britain before, but was full of confidence in the saddle as he brought the six-year-old home in the King’s Stand Stakes to become only the second ever Hong Kong-trained winner at the meeting.
Little Bridge (12-1) settled the issue with a telling turn of foot a furlong out.
Bated Breath tried to challenge, but was still threequarters of a length down at the line with Edward Lynam’s Sole Power third and Medicean Man fourth in the hands of Black Caviar’s jockey Luke Nolen.
Hototo (14-1) galloped on strongly to land the Windsor Castle Stakes by half a length for North Yorkshire trainer Kevin Ryan.
