Frank Francis Frisch, nicknamed "the Fordham Flash" or "the Old Flash", was an American professional baseball second baseman and manager. He played in Major League Baseball (MLB) for the New York Giants (1919–1926) and St. Louis Cardinals (1927–1937), and managed the Cardinals (1933–1938), Pittsburgh Pirates (1940–1946), and Chicago Cubs (1949–1951). He is a member of the National Baseball Hall of Fame and Museum and the St. Louis Cardinals Hall of Fame Museum. He is tied with Yogi Berra for most World Series doubles at 10 and holds the record for the most World Series hits at 58 for a player who never played for the New York Yankees, exceeded only by Berra and Mickey Mantle.

In baseball and softball, second baseman, abbreviated 2B, is a fielding position in the infield, between second and first base. The second baseman often possesses quick hands and feet, needs the ability to get rid of the ball quickly, and must be able to make the pivot on a double play. In addition, second basemen are usually right-handed; only four left-handed throwing players have ever played second base in Major League Baseball since 1950. In the numbering system used to record defensive plays, the second baseman is assigned the number 4.
