O'Brien signaled his likely plans by nominating the Mile as Rock Of Gibraltar's first preference, with the Classic being Hawk Wing's preferred objective. ``But that doesn't mean the situation cannot change,'' the trainer said.
Irish and English Derby winner High Chaparral, third in the Prix de l'Arc de Triomphe recently, is named to the Turf. O'Brien has entered five for the Juvenile, a race he won last year with Johannesburg. The 2-year-olds – Hold That Tiger, winner of the Grand Criterium, Tomahawk, Van Nistelrooy, Ontario and Marino Marini – were also entered in the Darley Dewhurst Stakes at Newmarket on Saturday.``A lot of other things will have to be taken into consideration before we finalize plans for the Juvenile,'' he said. Also entered by O'Brien is Shadwell Mile (gr. IT) winner Landseer in the Mile and Reach For The Moon, who finished third in the Meon Valley Studs Fillies' Mile at Ascot last month, for the Juvenile Fillies.
Last year O'Brien had his largest onslaught in the Breeders' Cup when he ran seven at Belmont Park, including Johannesburg.
O'Brien's entries were joined by the Sir Michael Stoute-trained duo Golan in the Turf and the filly Islington, who was named to the Filly & Mare Turf, following her run in the Prix de l'Arc de Triomphe. Godolphin's Kazzia is also entered in that race.
The Breeders' Cup will unveil the fields for the eight races that make up the World Thoroughbred Championships on Thursday.
