Raven's Pass was the first horse out of the European barn for morning track work at Santa Anita today and looked completely relaxed in his work under Frankie Dettori.
The ever-popular Dettori regards the Breeders' Cup as a special event, and a win in the Classic is one he would dearly like on his glittering CV.
He will ride the John Gosden-trained colt for the first time in the €8million contest, a race in which he finished a desperately close second aboard Sakhee at Belmont in 2001.
He said: "It is 21 years since my first ride at a Breeders' Cup and I'm looking forward to my rides this time, especially Raven's Pass, although most of my best horses had injuries and have not been able to get here.
"Raven's Pass was happy with himself. He had every reason to boil over but was just himself and I was delighted with him."
