foul ball, requiring the batter and all runners to return to their respective bases, whether it is caught or not. Additionally, if a ground ball or a bunted ball lands in foul territory and the ball rolls back into bounds before reaching either first or third bases without being touched by either a fielder or a runner, then said ball is considered fair. Once the batter and any existing runners have all stopped at a base or been put out, the ball is returned to the pitcher, and the next batter comes to the plate. After the opposing team bats in its own order and three more outs are recorded, the first team's batting order will continue again from where it left off. When a runner reaches home plate, he scores a run and is no longer a base runner. He must leave the playing area until his spot in the order comes up again. A runner may circle the bases only once per plate appearance and thus can score no more than a single run. In the American, Pacific, and both Cuban leagues, there is a tenth player, a designated hitter, who bats for the pitcher. Batting Each plate appearance consists of a series of pitches, in which the pitcher throws the ball towards home plate while a batter is standing in the batter's box (either right or left). With each pitch, the batter must decide whether to swing the bat at the ball in an attempt to hit it. The pitches arrive quickly, so the decision to swing must be made in less than a tenth of a second, based on whether the ball is hittable and in the strike zone, a region defined by the area directly above home plate and between the hollow beneath the batter's knee and the midpoint between the top of the shoulders and the top of the uniform pants. In addition to swinging at the ball, a batter who wishes to put the ball in play may hold his bat over home plate and attempt to tap a pitch lightly; this is called a bunt. Good bunting technique has been described as "catching the ball with the bat." On any pitch, if the batter swings at the ball and misses, he is charged with a strike. If the batter does not swing, the home plate umpire judges whether the ball passed through
