The first deaf baseball player joined the pro ranks in 1883. By 1901, four played in the major leagues, most notably outfielder William "Dummy" Hoy and pitcher Luther "Dummy" Taylor. Along the way, deaf players developed a distinctive approach, bringing visual acuity and sign language the sport. They crossed paths with other pioneers, including Moses Fleetwood Walker and Jackie Robinson. This book recounts their great moments in the game, from the first all-deaf barnstorming team to the only meeting of a deaf batter and a deaf pitcher in a major league game. The true story--often dismissed as legend--of Hoy, together with umpire "Silk" O'Loughlin, bringing hand signals to baseball is told.
