Book excerpt: In more than a century of baseball history, there is only one player who has won the most championship rings -- Yogi Berra. He has ten of them, in fact. One for each and every finger. In Ten Rings, Yogi, for the first time, tells the stories behind each of those remarkable championship seasons, spanning 1947 through 1962, baseball's golden years. It was a time when players played for the love of the game, a time when dynasties were born and baseball became the national pastime. And what a pastime it was. With Yogi Berra at their heart, Casey Stengel's Yankees took on their heralded archrivals: the Cleveland Indians, the New York Giants, the Brooklyn Dodgers, and, of course, the Boston Red Sox. And with those teams was Yogi's constellation of contemporaries, a who's who of the Hall of Fame: Joe DiMaggio, Mickey Mantle, Sandy Koufax, Willie Mays, Duke Snider, Ted Williams, Jackie Robinson, Phil Rizzuto, and many others. Each season brought its own drama, and it's all brought to life by the man who witnessed it. Ten Rings is a one-of-a-kind story told by a one-of-a-kind guy, baseball's elder statesman, the beloved Yogi Berra.
