Grover Greer "Bud" Delp was an American Hall of Fame Thoroughbred racehorse trainer best remembered for his conditioning of Hall of Fame colt, Spectacular Bid.
Bud Delp began his career as a Thoroughbred trainer in 1962 and in 1980 was voted the Eclipse Award for Outstanding Trainer. Delp, along with John J. Tammaro, Jr., King T. Leatherbury and Richard E. Dutrow, Sr. were known as Maryland racing's "Big Four" who dominated racing in that state during the 1960s and '70s and who helped modernize flat racing training.
During his career, Bud Delp's horses won 3,674 races and earned purses totaling nearly $41 million. In 2002, an honor he said he was most proud of, Delp was inducted into the United States' National Museum of Racing and Hall of Fame.
Delp remained a lifelong resident of Maryland and died in 2006 at his home in Ellicott City, aged 74.
