Brametot has rallied late to snatch victory in the Prix du Jockey Club (French Derby) at Chantilly to give trainer Jean Claude-Rouget his third success in the race.
After Brametot missed the start, his rider Cristian Demuro took his time and switched Brametot to the outside to deliver his challenge in the straight where the colt overhauled the field to add the Derby to his French 2000 Guineas victory.
Coral halved Brametot to 8-1 for the Prix de l'Arc de Triomphe, with RaceBets going 10-1.
Connections will get together to plan a program for the rest of the season for Brametot, with the Arc already in their thoughts.
"He is a very good horse with a very good trainer and very good jockey. Today was magical. He did something special," Sylvain Vidal, racing manager for Gerard Augustin-Normand who owns the horse with Al Shaqab Racing, said.
"We will have to talk with the Al Shaqab team and with Jean-Claude Rouget, but maybe he can go for the Arc.
"He may have one more race before the Arc, but we will have to see."
Rouget said it was a satisfying win, especially after a virus had affected some of his horses.
"It's huge.," he said.
"It is all the more beautiful after the virus that touched one of my barns.
"We were lucky that neither Brametot nor Mekhtaal (winner of last month's Prix d'Ispahan) were in this barn."
