Whirl might not be the best 3-year-old filly currently trained by Aidan O’Brien, but she’s the star of the Sunday card at Longchamp.
The annual preview program for the Prix de l’Arc de Triomphe includes three Arc preps: The Group 2 Prix Foy for older horses, the Group 2 Prix Niel for 3-year-olds, and the Group 1 Prix Vermeille, for fillies and mares. Whirl is set to face five foes in the 1 1/2-mile Vermeille, for which she was an odds-on favorite with British bookmakers as of Friday.
