BALLYDOYLE stars So You Think and Await The Dawn are among 15 pre-entries for the Breeders' Cup Classic on Saturday week.
So You Think touched down on European soil having carried all before him in Australia, but while he has since won four times, including three Group Ones, the giant colt has also suffered three defeats.
He is set to take to the dirt surface for the first time at Churchill Downs.
Aidan O'Brien has also entered Await The Dawn, beaten at odds-on in the Juddmonte International at York, but connections have declared his first preference as the Breeders' Cup Turf.
Uncle Mo, Gio Ponti and Havre De Grace are three of the better-fancied entries for the home team.
Joining Await The Dawn in the Breeders' Cup Turf could be stable companion St Nicholas Abbey and Michael Stoute's beaten St Leger favourite Sea Moon.

O'Brien has Crusade and Daddy Long Legs engaged in the Breeders' Cup Juvenile, with the latter in the Juvenile Turf as a second preference.
Leading Irish National Hunt jockey Paul Carberry feels the controversial new whip rules enforced in Britain lack common sense.
"I don't come over too often anyway, especially for the smaller meetings during the week, so it won't effect me as much as others," said Carberry.
"I don't agree with the rules and I don't think they are going to be great for the big meetings.
"I came over for Cheltenham earlier this month and you are thinking about it (use of the whip) all the time instead of focusing on riding a race. There is just no common sense. The stewards are there to do a job and now they just count how many times a jockey hits a horse.
