Leigh Montville's Ted Williams: The Biography of an American Hero is the definitive biography that baseball fans have been waiting for. Montville, who was a sports columnist for the Boston Globe and then a senior writer for Sports Illustrated is an admitted Red Sox and Williams fanatic, and his passion for his hero rings clearly from every page, along with his clear baseball expertise. But Montville does not hide Williams's flaws. The young Williams was temperamental and justified bad behavior with batting prowess that could excuse just about anything. Quick to anger, "the Kid" had a gift for foul language, too. Montville's study offers insides accounts of Williams's obsessive development as a hitter and his constant struggle to perfect his swing (mistakenly called "natural" by sports writers with little understanding of his extensive preparation). The chapter on 1941, perhaps the greatest year in his career, draws on research and interviews never before published. Montville lets whole passages stand uninterrupted--from Williams's manager, Joe Cronin, from his teammate Dom DiMaggio, and from other players and baseball officials who tell the story of Williams's quest for a .400 batting average. The tale of the final day of the season (when he refused to be benched and went six for eight in a double header to jump from .39955 to his final total, .406) is as pulse-pounding as any thriller. Alongside its essential focus on Williams's baseball life, the book also delves into his military service during both World War II and the Korean War, his passion for sports fishing, and his commitment to helping children through the Jimmy Fund. Finally, Montville devotes a chapter to the controversy after Williams's death, exposing the back-and-forth among Williams's heirs in the bizarre decision to freeze his body in a cryogenic warehouse in Scottsdale, Arizona. Montville's biography makes a good case that Williams was, if not the greatest hitter ever to play the game, certainly among them. For his focused, scientific approach to hitting, Williams is unmatched in the history of the game. His life, marred perhaps by a temper and occasional immaturity that soured his reputation in Boston, is one of true sports greatness. Early in the book, Montville argues that Williams is less appreciated today than he might be because he played out most of his 19-year career in the era before televised highlights. But with Montville's efforts to capture first-hand accounts of Williams's achievements, The Splendid Splinter's legacy is assured. --Patrick O'Kelley
