Big Leaguer

Big Leaguer is a 1953 film. It starred Edward G. Robinson and was the first film directed by Robert Aldrich.
Although this story is fiction, Robinson's character in it, Hans Lobert, was an actual baseball player who played for five Major League Baseball teams and managed the Philadelphia Phillies. Third-billed in the cast, Jeff Richards was a professional ballplayer before he became an actor, and Hall of Fame pitcher Carl Hubbell appears as himself.
