Justify was bred on the Glennwood Farm in Kentucky. This farm and horse breeding enterprise is run by John D. Hunter and his daughter Tanya Hunter.

Justify, born on March 28, 2015, was part of the penultimate crop of the stud Scat Daddy, a stallion who had achieved great success on both dirt racecourses in the United States and turf in Europe and South America.

In 2016, the young Justify was sold for $500,000 at the Keeneland September Yearling Sales. The buyer was a new partnership where WinStar Farm was the majority owner (60%), China Horse Club owned 25% and SF Racing 15%. In March 2018, Starlight Racing and Sol Kumin´s Head of Plains bought into the partnership.

Justify was initially trained by Rodolpho Brisset at Keeneland. After pulling a muscle, the horse was left to recover and grow for a while, before being sent to the trainer Bob Baffert at Santa Anita in January 2018.

Yarn and Preach are full sisters, with Mr. Prospector as their sire. Justify is thus linebred 3 x 5 x 5 to Mr. Prospector.

It is also worth noticing that Justify is a descendant of Northern Dancer through no less than six of his ancestors: Storm Cat, Yarn, Nijinsky, Deputy Minister, Preach, and Baldski.

Further back, Justify´s pedigree includes the U.S. Triple Crown title holders Seattle Slew (through A.P. Indy), Secretariat (through both A.P. Indy and Storm Cat), Count Fleet (through Mr. Prospector and Primal Force), War Admiral, Omaha, and Gallant Fox. Also, Nijinsky won the English Triple Crown.


In September 2019, The New York Times revealed that Justify had tested positive for the banned performance-enhancing substance scopolamine. The positive test came just a few days after Justify´s win at the 2018 Santa Anita Derby.
