Gleneagles will break from stall five in the Breeders' Cup Classic on the dirt at Keeneland on Saturday.

The dual 2000 Guineas and Royal Ascot winner, trained by Aidan O'Brien and ridden by Ryan Moore, was last seen finishing sixth behind Solow in the Queen Elizabeth II Stakes at Ascot on ground that was considered too testing.

Ballydoyle's prized asset will be up against an awesome foe in American Triple Crown winner American Pharoah, who has been draw in stall four in the 10-runner field.

Other solid rivals to Gleneagles include Beholder (stall 10), Tonalist (one) and Honor Code (nine).
