When the infielders throw the ball to each other after an out, as long as there are no base runners.

The purpose is as much traditional as anything else, but also serves to keep the infielders' throwing arms active. Typically, if an out is made at first base, the first baseman will throw to the second baseman, who throws to the shortstop, who throws to the third baseman, who returns the ball to the pitcher. Patterns vary from team to team, but the third baseman is usually the last infielder to receive a throw, regardless of the pattern.
