The High Chaparral horse stretched away from Campanologist and Famous Name at the business end under Ryan Moore and he was drawing further and further clear as he approached the line which he crossed four and a half lengths to the good.
Bringing up a treble for Aidan O'Brien following the earlier successes of Reply and Alexander Pope So You Think prompted his trainer to say: "It is great to have him in this part of the world.
"Ryan was delighted with him. The minute he asked him he responded immediately. The plan was here and then the Prince Of Wales.
"It was important that Ryan got a sit on him.
"He is an incredible horse. When you look at him in races you notice that the others are flat to the boards around him.
"He'd have no problem winning a mile Group 1 race. We'll take it one race at a time with him and as regards riding plans we're lucky to have some top-class riders around."
