American Pharoah, the racing legend owned by Egyptian-born Jewish businessman Ahmed Zayat, won the Breeders’ Cup Classic in Kentucky to take his prize-money earnings to a staggering £5.5 million.
The Keeneland victory added to his Triple Crown success in which he landed the Belmont and Preakness Stakes and the Kentucky Derby – the first time that had been achieved for 37 years.
American Pharoah, who won nine of his 11 races, will now be retired to stud.
Zayat said: “What a horse, the kindest, friendliest, happiest, easiest, most brilliant horse I have ever seen in my life.
