Although Willie Mays is often regarded as the greatest all-around player in baseball history, his stats aren't his true measure. Looking back on his humble Alabama childhood, his stint in the Negro Leagues, service in Korea, and long baseball career, the "Say Hey Kid" offers the wisdom earned from a lifetime of meeting challenges with positivity and integrity. In 24 chapters—to correspond with his iconic uniform number—Mays's anecdotal memoir includes impressions of Jackie Robinson, Yogi Berra, Hank Aaron, Whitey Ford, Stan Musial, and Alvin Dark, as well as an account of his friendship with Barack Obama.
