No immortal in the history of baseball retired so young, so well, or so completely as Sandy Koufax. After compiling a remarkable record from 1962 to 1966 that saw him lead the National League in ERA all five years, win three Cy Young awards, and pitch four no-hitters including a perfect game, Koufax essentially disappeared. Save for his induction into the Hall of Fame and occasional appearances at the Dodgers training camp, Koufax has remained unavailable, unassailable, and unsullied, in the process becoming much more than just the best pitcher of his generation.

Except for his autobiography (published in 1966), Koufax has resolutely avoided talking about himself. But through sheer doggedness that even Koufax came to marvel at, Jane Leavy was able to gain his trust to the point where they talked regularly over the three years Leavy reported her book. With Koufax’s blessing, Leavy interviewed nearly every one of his former teammates, opponents, and friends, and emerged with a portrait of the artist that is as thorough and stylish as was his command on the pitching mound.
