Secretariat's brother Straight Flush

Straight Flush, half-brother to Secretariat

He has since passed away, but the story of Secretariat’s half-brother is heartwarming. At the age of 24, Straight Flush (Riva Ridge x Somethingroyal, Secretariat’s dam) was in rough shape and destined for the slaughterhouse in Texas when racing writer Stephanie Diaz bought him for $200.

Straight Flush was foaled in 1975 at Meadow Stable in Virginia, the same place Secretariat was born five years earlier. Hopes were high for the bay colt, though Straight Flush didn’t live up to his famous half-brother’s success. His first win was at Santa Anita with legendary jockey Bill Shoemaker, but no other significant wins followed. He stood at stud in Louisiana and Texas and ultimately sired 176 purebred Thoroughbred foals.

By horse-breeding standards, only those horses that have the same dam are considered half-siblings. Straight Flush and Secretariat were out of the same mare, so they were half-brothers. However, Secretariat and other horses sired by Bold Ruler are not called siblings.
