Dr. Rudolph Alvarado's compelling and in-depth biography captures the story of Joe Hernandez, a Mexican-American, who despite his ethnic background became thoroughbred horse racing's greatest race caller at a time when most Mexicans and Mexican-Americans were being repatriated to Mexico due to America's Great Depression. Alvarado's biography uncovers the extent to which Hernandez went to fit into this Anglo-American dominated world, and reveals that Hernandez's impact on the sport of thoroughbred horse racing went far beyond that of being a race caller. This is the first biography ever written about a Mexican-American involved in the sport of horse racing and the first to capture the social impact that a sport played in shaping the life of a Mexican-American. The book comes with a CD of Hernandez's most famous race calls. Included among them are his call of Seabiscuit's victory in the 1940 Santa Anita Handicap and Johnny Longden's last ride in 1966.
