Willie Mays in midair, 1954
Today marks the 60th anniversary of Willie Mays' 1951 major league debut.
OK, so maybe it's a slightly obscure anniversary. But it's baseball season! Plus, these never before published photos were taken by Life legendary photographer Loomis Dean; it seems appropriate that he'd be photographing Mays, a baseball legend in his own right. See the full gallery of Mays in his early career over at Life.
A never before published photo shows 22-year-old Willie Mays at spring training in 1954, the year the Giants won the World Series — the sole championship of Mays' long career.
