Eddie Arcaro [February 19, 1916 - November 4, 1997] is considered the best rider to have ever played at the Kentucky Derby. Specifically, Arcaro is a five-time Kentucky Derby winner. He in fact is considered the greatest jockey in American horse racing history. That honor comes from the fact of his being one of only two jockeys to win the Derby five times. But he also is the only jockey to have won the U.S. Triple Crown twice: in 1941 on Whirlaway, and in 1948 on Citation.
Issac Burns Murphy raced in the Kentucky Derby 11 times and won the event in 1884 on Buchanan, on Riley in 1890 and on Kingman in 1891. He had 1,412 starts with 628 wins which is a record that will last forever.
Chicken Wing, a man won 8,000 dollars on a outside bet.
No genetically roan thoroughbred has ever won the Kentucky Derby. However, the filly Winning Colors was registered as Roan/Gray. The Jockey Club groups Grays and Roans in the same category even though they are very different genetically. Winnings Colors was actually genetically a gray, so technically no roan has ever won the Kentucky Derby.
Technically, a mare is defined as a female horse over the age of three. A filly is a female horse three years or younger. Since the Kentucky Derby is a race for 3-year-olds only, no mare has ever won. However, three fillies have won the Kentucky Derby: Regret (1915); Genuine Risk (1980); and Winning Colors (1988).
