Baseball has been an Olympic sport since 1992.
Baseball is a team sport that is popular in the Americas and East Asia.

In the United States, baseball has often been called the "national pastime", and the total attendance for Major League games is more than that of all other American professional sports combined. Among American television viewers, however, it has been surpassed in popularity by football and car racing.

Baseball is thought to be a direct descendant of cricket and rounders, though the game's origins are uncertain. The sport is very similar to softball. In its usual form, the game of baseball is played between two teams of nine players at a time on a playing field consisting of four bases, arranged in a diagonal square ("the diamond") and a large outfield extending from two adjacent sides of the diamond.
