Remembering John Shirreffs: Celebrated Trainer of Zenyatta and Giacomo Passes Away at 80
Notable Horse Trainer John Shirreffs Passes Away at 80
John Shirreffs, a prominent figure in thoroughbred racing and the trainer of legendary mare Zenyatta, passed away in Southern California on Thursday at the age of 80. The cause of death has not been disclosed.
With an impressive record of 3,589 starts, Shirreffs achieved 596 wins, accumulating over $58.5 million in purses throughout his career. He was a familiar presence at local racetracks, often seen ponying his horses during morning training. Notably, he preferred to avoid the spotlight after victories, allowing his wife, Dottie Ingordo, to take center stage during celebrations.
Shirreffs first garnered national attention in 2005 when he trained Giacomo to a stunning Kentucky Derby victory at 50-1 odds. The horse, part-owned by renowned music producer Jerry Moss, solidified Shirreffs’ reputation as a top trainer. He continued to train for Moss until the latter’s passing in 2023.
Zenyatta, a remarkable horse known for her dynamic personality and racing prowess, became Shirreffs’ most celebrated trainee. She amassed a 19-race winning streak, culminating in a breathtaking last-to-first victory in the 2009 Breeders’ Cup Classic at Santa Anita Park—a feat praised as "unbelievable" by race caller Trevor Denman.
Born in New York, Shirreffs’ journey into horse racing was serendipitous. He recounted how a friend encouraged him to move west after returning from Vietnam. "I had no place to go, but I had a friend who knew somebody," he shared in an interview. "I didn’t know anything about horses except I’d seen a lot of cowboy movies."
His entry into the sport began when he agreed to work for a horseman named Jim Matthews, where he gained invaluable experience. "I didn’t get paid anything, just room and board," Shirreffs recalled. He later took on a greater role at Loma Rica Ranch, where he worked for over a decade before training horses at fairs.
Shirreffs was once asked whether his experiences in Vietnam or training horses presented greater challenges. He chose not to elaborate on that comparison.
In a statement, Santa Anita expressed their condolences, reflecting on Shirreffs’ impact on the racing community. “Every horse who races at Santa Anita must first pass by the statue of John’s greatest trainee, the wonderful mare Zenyatta. Our deepest condolences are extended to John’s wife, Dottie, and his family, including those who worked closely with him over the years. May his memory be a blessing.”
As of now, no funeral arrangements have been announced.
