Day Star

Day Star (1875–1893) was the winner of the 4th annual Kentucky Derby held at Churchill Downs on May 21, 1878. He was a chestnut colt that was foaled in Kentucky and was sired by Star Davis (by the successful Glencoe). His dam was Squeeze 'Em who was sired by Lexington, a foundation sire of many modern Thoroughbred lineages.
Day Star won the Derby by two lengths in an official time of 2:37.25, beating the race record set by Aristides in 1875, and winning a total of $4,050.
In his career, he had 42 starts, 11 wins, 7 places and 5 shows.
A 1910 "Daily Racing Form" article states that Day Star was sold after his racing career and stood at stud on a western farm, dying at the age of 18 years in 1893.
