Article: The field is made up of an infield, an outfield, a pitcher's mound, 3 bases, and home plate. The infield is the diamond-shaped part of the field bounded by home plate (where the batter stands to hit) and the three bases (first base, second base, and third base). The outfield is the part of the playing area located outside the diamond-shaped infield. The pitcher's mound is a small hill in the middle of the infield, where the pitcher stands. " Whenever a batter appears at home plate, he earns an "at bat" (AB). When a batter hits the ball into the infield or outfield and reaches a base safely, he earns a hit (H). When a batter hits the ball outside the foul lines that serve as boundaries for the playing field, this is not a hit it's a foul. When a batter receives four pitches that are "balls" that is, they were outside of the strike zone, where the pitcher must aim to get a strike then he walks to first base. This is known as a "base on balls" (BB). If a batter or his equipment is hit by a pitch, then he walks to first base. This is known as a "hit by pitch" (HBP). When a batter hits the ball into the air, sacrificing his own at bat in order to give a teammate already on base the opportunity to score, this is called a "sacrifice fly" (SF). A player from the opposing team may catch the ball in the air, meaning that the batter is out, but another player may get to advance or score.
