noun. base·​ball ˈbās-ˌbȯl. : a game played with a bat and ball by two teams of nine players each on a field with four bases that mark the course a runner must take to score. also : the ball used in this game.

Baseball, as it was before the rise to dominance of its altered New York variant in the 1850s and 60s, was known variously as base ball, town ball, round ball, round town, goal ball, field-base, three-corner cat, the New England game, or Massachusetts baseball.

The game is divided into nine innings, each divided into two halves. In the top half of the inning, the players of one team successively come to bat and attempt to score runs, while the other team plays in the field and attempts to stop the offensive team from scoring. In the bottom half, the teams swap places.
