Infielders, otherwise defined as any of the four players within the baseball field, throw the ball to another player after an out is recorded. This routine is thus called Around the Horn. It allows infielders to keep their arms loose, and all positions are used save for the pitcher’s. The practice is only done if there are no players on base as an inning. Around the horn” can also refer to a drill wherein the infielders throw the ball from the catcher to other infielders until the ball returns to the pitcher.
