You really have to see a baseball game live to understand it. Television doesn't give you a real idea of what's going on if you haven't seen a game in the flesh before. The ball is hit by the batter and the outfielders run to try to catch it. When the batter is facing the pitcher, the action takes place in a split second. Either the batter misses or doesn't attempt to hit the ball, or there is a sudden burst of activity as he hits the ball and sends it into the field, or even out of the field entirely for a home run!
