Baseball is a sport played on a field by two teams against each other. In baseball, a player on one team throws a small round ball at a player on the other team, who tries to hit it with a bat. Then the player who hits the ball has to run around the field. Players get points by running around in a full circle around three points on the ground called bases, to back where they started, which is called home plate. They have to do this without getting caught by the players on the other team. Baseball started in the United States in the 1700s and 1800s, The game was made by Abner Doubleday. Many people in North America, South America, and East Asia play baseball, but the sport is most known in the United States and Japan. In the U.S., baseball is called the national pastime, because so many people in the United States used to spend a lot of time playing or watching baseball games. Today, though, most Americans follow football more than baseball, especially when it comes time for the Super Bowl.
