Deputed Testamony, the last Maryland-bred to win the Preakness Stakes (gr. I), died Sept. 18 and was buried at the Boniface family's Bonita Farm in Darlington, Md., next to his sire and dam. At 32 years of age, he was the oldest living classic winner in North America.
Deputed Testamony was bred and raced by William Boniface and his son, J. William Boniface, in the name of Bonita Farm in partnership with Francis P. Sears. By Traffic Cop out of the Prove It mare Proof Requested, Deputed Testamony was a stakes winner at ages 2 through 4 and an earner of $674,329 while trained by the younger Boniface.
Deputed Testamony, who skipped the Kentucky Derby (gr. I), captured the Preakness by 2 3/4 lengths over Derby runner-up Desert Wine, with Derby winner Sunny's Halo finishing sixth as the 11-10 favorite. Deputed Testamony contested the Belmont Stakes (gr. I), finishing sixth.
In addition to capturing the Preakness, Deputed Testamony set a track record at Pimlico in the 1984 City of Baltimore Handicap at 1 1/16 miles in 1:40 4/5 that still stands and one at Meadowlands in the one-mile Play the Palace Stakes as a 2-year-old. He also won the Haskell Invitational Handicap (gr. I) at Monmouth, the Governor’s Cup Handicap (gr. III) at Bowie, Pimlico's Federico Tesio Stakes, and the Keystone Stakes at Keystone at what is now Parx Racing.
Fondly known as DT around the farm, Deputed Testamony retired to stud in 1984 after being syndicated for $5 million and initially stood for $25,000 live foal. Due mostly to Deputed Testamony's success, the Bonifaces moved their breeding operation from a smaller farm in Bel Air, Md., to Bonita’s current location.
Deputed Testamony sired 21 stakes winners including graded winners Under Oath, Testafly and Gold Fleece. His daughters have produced grade I winners Bellamy Road and Whitmore’s Conn.
"The son of very modestly bred parents, Deputed Testamony reached the highest pinnacle of racing, a true testament to all horse breeders that anything is possible in the great sport of horse racing," Boniface said. "A more courageous horse never looked through a bridle."
