This first book-length biography of Jimmy Collins examines the life of an intensely private, business-oriented ballplayer who was the first third baseman to be inducted into the Baseball Hall of Fame. Collins' life is covered in depth from his early years growing up in Buffalo, through his 14-year major league baseball career 1895-1908 primarily in Boston, to his post-baseball life as a real estate investor. This book sheds new light on Collins' motivations to leverage his baseball success--which included leading Boston to victory in the first modern-day World Series in 1903--into lucrative baseball contracts to fund his real estate investments. When he led the Boston Americans to successive American League championships in 1903 and 1904, Collins was instrumental in the foundation of today's highly successful Boston Red Sox franchise and its intense rivalry with the New York Yankees.
