At age two, he won eight out of his nine starts and was voted both the Sovereign and Eclipse Awards for Champion 2-Year-Old in Canada and the United States respectively.
Although his three-year-old campaign was restricted by injury, Deputy Minister rebounded at age four with several major wins.
[4] Deputy Minister originally raced for the Levys, who sold a half interest to Kinghaven Farms during the colt's two-year-old campaign.
Due Process Stables purchased a half interest in the colt in January 1982 for a reported $6 million, then became the horse's sole owner during 1983.
Deputy Minister was trained by Bill Marko for his first six races as a two-year-old before he was moved to the barn of John J. Tammaro Jr.
After Marko did not get the necessary visas for the horse to race in the Hopeful Stakes in the United States in August, Deputy Minister was formally moved to the Tammaro's stable.
He quickly rebounded with two Grade I stakes wins:[1][4] Deputy Minister was named the Canadian Horse of the Year and also received Sovereign and Eclipse Awards as the Champion Two-Year Colt in Canada and the United States respectively.
[1] On the Experimental Free Handicap, he was the co-highweight with Timely Writer at 126 pounds, the first Canadian-bred horse to achieve this honor.
In his last six starts, Deputy Minister finished second twice (in the Meadowlands Cup and the Stuyvesant Handicap), third twice (in an allowance race and the Vosburgh Stakes) and was unplaced twice.
"[11] Deputy Minister was retired to stand at stud at the Maryland branch of Windfields Farm, where he sired future U.S. Hall of Famer Go for Wand.
As a result, Deputy Minister was moved to Fred Seitz's Brookdale Farm in Versailles, Kentucky, where he spent the rest of his life.
One of his daughters, Better Than Honour, became Kentucky Broodmare of the Year after siring back-to-back winners of the Belmont Stakes, Jazil and Rags To Riches.
