The term 'SPACES BETWEEN OUTFIELDERS' can be summarized as GAPS, which is a four-letter word. This term refers to the area between the outfielders in a baseball game. The outfielders are positioned in such a way that they cover the entire outfield area, leaving no GAPS for the ball to pass through. The spaces between the outfielders are important for the defense of the team, as it allows them to cover more ground and prevent the ball from going too far.
