THE big story of this year’s Longines World’s Best Racehorse Rankings is unquestionably the Bob Baffert-trained American Pharoah (134). His rampage through the Triple Crown series in which he became the first horse to successfully complete it since Affirmed in 1978 captured America’s imagination and he carried that brilliance through the remainder of the season, putting up even bigger performances in the Haskell Invitational Stakes at Monmouth Park and the Breeders’ Cup Classic. His legacy will live on for as long as horses are raced in America and his World Champion-winning rating puts him up there as the highest-rated horse that has been trained in America in the last decade.
