Justify (horse)  Justify (foaled March 28, 2015) is a retired American Thoroughbred racehorse who is the 13th and most recent winner of the American Triple Crown, accomplishing the feat by winning the Kentucky Derby, Preakness Stakes, and Belmont Stakes in 2018. He first attracted attention with a win in his first start on February 18, 2018, followed by two more victories, including the Grade I Santa Anita Derby, to qualify for the 2018 Kentucky Derby. Justify then won that race, the 2018 Preakness Stakes, and the 2018 Belmont Stakes to win the Triple Crown. He was retired undefeated several weeks after the Belmont, thereby becoming the only American Triple Crown winner who never lost a race in his career. Justify is only the second horse to win the American Triple Crown with an undefeated record, following Seattle Slew, who Justify is descended from, others Justify descends from include Secretariat, Count Fleet, War Admiral, Omaha, and Gallant Fox, all of whom also won the American Triple Crown. He is also a descendant of English Triple Crown winner Nijinsky. Of the 13 American Triple Crown winners, Justify is the first who did not race as a two-year-old. On September 11, 2019, it was revealed via "The New York Times" that Justify tested positive for scopolamine, a banned substance that can be performance enhancing, in excess of what is normally found in tainted feed. The positive came just a few days after the Santa Anita Derby and would have normally resulted in a disqualification but the California Horse Racing Board ultimately dismissed the case. Justify is a chestnut stallion with a large white blaze on his forehead. He was bred in Kentucky by Canadian John D. Gunther, who runs Glennwood Farm with his daughter Tanya. Although the Gunthers have a small breeding operation, their 2015 foals also included Without Parole, a Group I winner at Royal Ascot, Vino Rosso, a graded stakes winner who raced against Justify in both the Kentucky Derby and Belmont Stakes, and Grade I winner Competitionofideas. For this accomplishment, Gunther earned the 2018 Eclipse Award for Outstanding Breeder. Gunther also bred Justify's dam, Stage Magic, a stakes-placed daughter of Ghostzapper. Stage Magic was subsequently named the 2018 Kentucky Broodmare of the Year. Justify was part of the second-last crop of Scat Daddy, who won the Champagne Stakes and Florida Derby.
