Ballydoyle horses at head of rankings Aidan O'Brien has the distinction of training both the top European juvenile colt and filly in the same year for the third time in his career. Air Force Blue and Minding were rated 124 and 120 respectively, with the rankings revealed at a ceremony in London. Ballydoyle colt Order Of St George was confirmed the world's leading stayer after achieving a rating of 124 for his 11-length triumph in the Irish St Leger at the Curragh, while O'Brien also trained the world's top three-year-old turf miler in dual 2000 Guineas and St James's Palace Stakes hero Gleneagles (122). Fellow Ballydoyle inmate Found (120), who saw off Golden Horn in the Breeders' Cup Turf, was crowned the best three-year-old turf filly over both 10 furlongs and a mile and a half. The Willie Mullins-trained Max Dynamite (117) was Europe's top older stayer, while the top older sprinting male was Eddie Lynam's Sole Power (118). Legatissimo, trained by David Wachman, was the top three-year-old filly miler with a rating of 116. Triple Crown hero American Pharoah beat Golden Horn to be named the 2015 Longines World's Best Racehorse . Bob Baffert's brilliant colt became the first horse since Affirmed in 1978 to claim the Kentucky Derby, the Preakness Stakes and the Belmont, but it was his devastating performance in the Breeders' Cup Classic at Keeneland that earned him a rating of 134. American Pharoah is the highest-rated North American-trained three-year-old since the United States became part of the International Classifications in 1995. Owner Ahmed Zayat said: "What a grand finale. American Pharoah is a horse of a lifetime. "Not only was he brilliant on the racetrack, he has connected with everyone in America. He brought us back hope. For 37 years we were waiting for a horse like that and he was finally the one. "What I want everyone to remember about American Pharoah is not only was he majestic and brilliant in the way he raced and how much he liked winning the way he did, is how much he was the people's horse." John Gosden's Golden Horn was the stand-out turf performer of 2015, winning the Epsom Derby, the Coral-Eclipse, the Irish Champion Stakes and the Prix de l'Arc de Triomphe and achieving a lofty rating of 130 in the process. Only Sea The Stars (136) and Frankel (140) have rated higher as three-year-olds on the grass than Golden Horn since the inauguration of the World Thoroughbred Rankings in 2004. Golden Horn's owner-breeder Anthony Oppenheimer said: "This is a great honour. These awards are fantastic."
