Purchased by A.B. Hancock in 1915, Wrack was the first major acquisition of a foreign stallion and launched the stallion division of Claiborne Farm in Kentucky to complement the main farm, Ellerslie, in Virginia.
Wrack was the first leading sire for the Paris, Kentucky operation, topping the Juvenile Sire List in 1926 and becoming the leading U.S. sire by number of winners in 1923, 1930 and 1931.
Wrack’s 30 career stakes winners included one of A.B. Hancock’s earliest Kentucky-bred champions, Careful, the Champion two-year-old filly of 1920 and Champion older mare of 1922. Another important offspring was produced when William Woodward’s Belair Stud sent Kentucky Oaks winner Flambette to Wrack. That fateful mating produced the mare, Flambino, who was in turn bred to Woodward’s Claiborne-based Triple Crown winner Gallant Fox, producing subsequent Triple Crown winner Omaha, who would also stand at Claiborne.
