Stoute has committed Pilsudski to the Group One feature two weeks after he chased home Peintre Celebre in the Prix de l'Arc de Triomphe. Michael Kinane will continue on the colt, leaving Aidan O'Brien to find a rider for Desert King. The race is one of the few big races to elude Stoute, for whom victory could clinch the trainers' championship.
"Pilsudski seems to have taken his race in the Arc well. The ground wouldn't matter for him," Stoute said. "There was always a question about whether Singspiel took in the Champion before the Breeders' Cup but now he is definitely aimed at the Breeders' Cup."
