Martin L. Fallon Jr., a retired jockey and trainer who conditioned California star Hillsdale, died Oct. 15 at Veterans Affairs Medical Center in Louisville. He was 87.Nicknamed Junie, Fallon trained Hillsdale during the horse's stakes-winning days of 1958-59. As a 4-year-old in 1959, Hillsdale won nine stakes, including the Hollywood Gold Cup Handicap, Santa Anita Maturity, and Aqueduct Handicap. The previous year, he captured five stakes. Fallon rode for eight years starting in the 1930s, but weight and Army service during World War II cut short his career, and he turned to training. He spent most of career training in New Jersey and Pennsylvania and for a time headed the United Thoroughbred Trainers of America and the New Jersey division of the Horsemen's Benevolent and Protective Association. He conditioned 14 stakes winners, five of which he owned, including homebreds Regal Hero and Strutting Sandal. The latter was bred in partnership with Dr. Alex Harthill.Fallon was preceded in death by his wife, Rosetta.
