The Vodafone Derby hero travelled with the same fluency and enthusiasm as at Epsom and much to the delight of a thrilled York crowd, he scooted clear under Frankie Dettori just ahead of the furlong pole.
King George winner Dylan Thomas gave chase but found Authorized’s blistering finishing kick too much and had to settle for second spot, a length behind the well-backed 6-4 favourite.
Ryan Moore had stole a march when racing solo on the stands side in the Eclipse aboard Notnowcato, but last year’s winner did not fare as well this time with the main pack and was a further three lengths behind in third.
Authorized, who strolled clear over the course and distance in the Dante three months ago, is the first since Troy in 1979 to win both the Derby and International in the same year, and the first three-year-old winner since Giant’s Causeway struck in 2000.
But his victory is much more of a personal success for his trainer Peter Chapple-Hyam, who was left bitterly disappointed after his Derby winner finished only second at Sandown, despite winning the race on the far side.
He said: “This probably means more than the Derby as he got beat (in the Eclipse) and people have been knocking him. I have had to read it every day, but luckily he can’t read and it doesn’t bother me.
“His work has been the same as normal but on Thursday he did an exceptional piece of work under Frankie and I knew we had him ready.
“There has been a lot of pressure to make him win but the pressure doesn’t bother me. I just wanted him to win to show he is as good a horse as I have always said he was.
“I got a bit worried when Frankie just sat there as I was thinking ’come on and go’ as all he does is gallop and that is what probably caught us out in the Eclipse.
“When I saw him today he looked back to himself. It is hard to go from the Dante to the Derby and then the Eclipse as no matter how easy you win, a horse is trained so hard for the Derby.
“That is why I wanted to come here rather than the Irish Champion Stakes so he can have another break before the Arc, which is where he will go next.”
Coral, Ladbrokes and William Hill all make the Montjeu colt the 2-1 favourite for the Longchamp showpiece in October, with totesport and VC Bet 5-2 and Cashmans 3s.
The next best in the ante-post lists is Andre Fabre’s Manduro, and Chapple-Hyam added: “Manduro is a whole new ball game, but I look forward to meeting him.”
From two furlongs out, cries of “come on Frankie” resounded around the course and Dettori returned to rapturous applause in a packed winner’s enclosure.
He said: “I have been as sick as a dog the last couple of weeks, but riding him today was the best cure.
“There was more pressure for the horse than for me and I just wanted him to prove that it wasn’t a fluke in the Derby and he has.
“He’s a great Derby winner. He’s beaten a King George winner and an Eclipse winner.
“He is one of the best horses I have ridden and I am delighted he has shown the world how good he is.
“I kept a close eye on Dylan Thomas and when I saw Johnny (Murtagh) pull him off the rail I kicked and always had two or three lengths in the locker. The further he went in the race the more I struggled to hold him.
“He has shown what a true champion he is and I can’t wait to ride him in the Arc – he ticks all the right boxes.”
Aidan O’Brien, trainer of Dylan Thomas, said: “He ran a blinder, but he’s a fast ground horse and just couldn’t quite pick up as well on that ground.”
Sir Michael Stoute philosophically said of Notnowcato: “Those are the best around and he never lets us down.”
