The "base stealing king" of the American League for 1939 will be George Case, the fleetfooted outfielder of the Washington Senators. From the way that he has been burning up the base paths, Clark Griffith considers him a threat to Ty Cobb's base-stealing record. Case started his professional baseball career as a pitcher with Connie Mack's rookie school four years ago. His natural speed forced a shift to the outfield when in 1937 he signed with Trenton. He signed with the Senators in 1938 and in 107 games last year, Case batted an even .300.
