Spanish Moon, who had been a best-priced 10-1 for the Breeders' Cup Turf at Churchill Downs, has been retired.
The Sir Michael Stoute-trained
six-year-old won six of his 16 starts, including the Grand Prix de
Saint-Cloud, and nearly £1.8 million in win and place prize-money.
He has not been seen since finishing fourth to subsequent Irish St
Leger winner Sans Frontieres in the Princess of Wales's Stakes at
Newmarket in July.
