A. Thomas Doyle
Andrew Thomas "Tommy" Doyle (September 23, 1917 – July 22, 1989) was an American Thoroughbred racehorse trainer known for his success with young horses. He was reported as both "Tommy Doyle" and "A. T. Doyle."
A native of Dublin, Ireland, Tommy Doyle came from a family with a long history in the sport of horse racing. He emigrated to the United States in 1951 and made his way to California where he eventually owned a ranch in Bradbury on which he raised and trained horses.
Widely respected for his ability to work with young horses, two-year-old fillies trained by Tommy Doyle won the Junior Miss and Del Mar Debutante Stakes a combined thirteen times. Among his best-known horses, Doyle trained Typecast to the 1972 American Champion Older Female Horse title and in 1975 conditioned Avatar to wins in the Santa Anita Derby [1] and the third leg of the U.S. Triple Crown, the Belmont Stakes.[2]
Tommy Doyle died from Alzheimer's disease at age 71 in 1989.[3]
