Explanation

Baseball is a game in which a player hits a ball with a bat and runs around the field, stepping on three bases before returning to where he started. Most baseball games last seven innings. During a typical baseball game, two teams of nine players each take turns being at bat while the other team stands in the field attempting to catch any balls that are hit and tag running players out before they are safe on a base. Though baseball was first played in 19th century England in the form of "rounders," it's been considered the US national sport since the early 20th century.
