Hitter

In baseball, batting is the act of facing the opposing pitcher and trying to produce offense for one's team. A batter or hitter is a person whose turn it is to face the pitcher. The three main goals of batters are to become a baserunner, drive runners home, or advance runners along the bases for others to drive home, but the techniques and strategies they use to do so vary. Hitting uses a motion that is virtually unique to baseball, one that is rarely used in other sports. Hitting is unique because unlike most sports movements in the vertical plane of movement hitting involves rotating in the horizontal plane.

In general, batters try to get hits. However, their primary objective is to avoid making an out, and helping their team to score runs. There are several ways they can help their team score runs. They may draw a walk if they receive and do not swing the bat at four pitches located outside the strike zone. In cases when there is a runner on third and fewer than two outs, they can attempt to hit a sacrifice fly to drive the runner in by allowing the runner on third to tag up and score. When there are fewer than two outs and runners on base, they can try to sacrifice bunt to advance the runner(s) or, with a runner on first or with runners on first and third, they can try a hit and run play, also designed to advance the runner(s). They might even be hit by a pitch, reach on an error or—if first is empty or there are two outs—on a dropped third strike.

The defense attempts to get the batter out. The pitcher's main role in this is to throw the ball in such a way that the batter either strikes out or cannot hit it cleanly so that the defense can get him or her out.
