Peter Miller

Peter L. Miller (born October 2, 1966) is an American Thoroughbred racehorse trainer who is best known for back-to-back double wins at the Breeders' Cup in 2017 and 2018. He has won multiple training titles at Del Mar Racetrack and his horses have accumulated over $68 million in career earnings. Career Miller was introduced to horse racing by his parents, who owned Winning Ways Stables. He became a groom for Hall of Fame trainer Charlie Whittingham in the 1980s, when his charges included Greinton and Palace Music. He later worked for trainers Mike Mitchell and Don Warren before setting up his own stable. For many years, Miller ran a relatively small stable with mostly claiming horses. He earned his first win on April 25, 1988 with a claimer named Dynashield. It was not until 2006 that he scored his first graded stakes win, with Fast Parade in the Nearctic Stakes when shipping to Woodbine Racetrack in Toronto. In 2007, he trained his first Grade I winner, Set Play in the Del Mar Debutante Stakes. Miller's next Grade I winner was Comma to the Top, who won the 2010 CashCall Futurity. Comma to the Top later finished second in the Santa Anita Derby but was nineteenth in the 2011 Kentucky Derby. After winning thirteen races and earning over $1.3 million, Comma to the Top was retired to become Miller's stable pony.
