In 1990, at age four, Criminal Type began to show promise on the U.S. dirt tracks, then at age five he won seven of eleven races entered and earned two Eclipse Awards including the most prestigious award of all, the Eclipse Award for Horse of the Year. Criminal Type won four consecutive Grade 1 races: The Pimlico Special, the Metropolitan Handicap, the Hollywood Gold Cup, and the Whitney Handicap. In his wins, Crimainal Type defeated 1989 Horse of the Year, Sunday Silence, eventual 1991 Horse of the Year, Black Tie Affair, U.S. Outstanding Sprint Horse Housebuster, and 1989 Belmont Stakes winner Easy Goer. Other quality horses vanquished by Criminal Type include Opening Verse, Lively One, Ruhlmann, and Flying Continental. Criminal Type was the last champion to run in the Calumet Farm devil's red and blue colors.
After suffering an injury in the Woodward Stakes, Criminal Type was retired to stand at stud at Calumet Farm where he sired two graded stakes race winners before he was sent in 1993 to a breeding farm in Japan. Criminal Type was the broodmare sire of 2003 Travers Stakes winner, Ten Most Wanted. Criminal Type died in Japan at age twenty on March 9, 2005 from a ruptured stomach. He had been scheduled to be returned to America as a pensioner at Old Friends Equine in Kentucky. Criminal Type has been a regular nominee to the Horse Racing Hall of Fame, but has yet to be named a finalist for induction. Many believe that Criminal Type has been overlooked by the Hall of Fame due to the scandals that engulfed Calumet Farm in the early 1990's, including the alleged murder of Criminal Type's sire, Alydar for insurance proceeds. A Federal judge in the Houston Division of Texas found Calumet and its President not responsible for the payment of the insurance pay-out on Alydar.
