Shortstop, abbreviate SS, is the baseball fielding position between second and third base. Shortstop is often regarded as the most dynamic defensive position in baseball, because there are more right-handed hitters in baseball than left-handed hitters, and most hitters have a tendency to pull the ball slightly, so more balls go to the shortstop than any other position. In the numbering system used to record defensive plays, the shortstop is assigned the number 6.
