Raymond William Schalk was an American professional baseball player, coach, manager and scout. He played as a catcher in Major League Baseball for the Chicago White Sox for the majority of his career. Known for his fine handling of pitchers and outstanding defensive ability, Schalk was considered the greatest defensive catcher of his era. He revolutionized the way the catching position was played by using his speed and agility to expand the previously accepted defensive capabilities for his position. Schalk was elected to the Baseball Hall of Fame in 1955.

Catcher is a position in baseball and softball. When a batter takes their turn to hit, the catcher crouches behind home plate, in front of the (home) umpire, and receives the ball from the pitcher. In addition to this primary duty, the catcher is also called upon to master many other skills in order to field the position well. The role of the catcher is similar to that of the wicket-keeper in cricket.
