Dual Cox Plate winner So You Think will race with blinkers and on Lasix in his attempt to create an Australian racing first in the US Breeders Cup Classic (2000m) at Churchill Downs in Kentucky on Sunday.
So You Think will be administered Lasix a drug legal in US racing but banned in Australia, UK and Ireland.
All but eight of the 180 horses running in the Breeders Cup events will race on Lasix.
Trainer Aiden O’Brien has decided to put blinkers back on So You Think at his first attempt on a dirt surface.
He won his first Cox Plate in 2009 with blinkers on when he led throughout..
O’Brien is very happy with how So You Think has travelled from Ireland to Kentucky.
Few Australian horses have contested a Breeders Cup, although 1983 Cox Plate winner Strawberry Road came closest to succeeding.
He ran fourth in the 1984 Breeders’ Cup Turf before returning the next year and going under by a nose to British mare Pebbles.
The Breeders Cup Classic (2000m) will be run on Sunday (10am, Aust, EST).
