Baseball Game Part is a term used to refer to an Inning, which is a unit of play in baseball. An inning consists of two halves, the top and the bottom, with each team taking turns batting and fielding. During an inning, each team has three outs, or chances to get the opposing team out. After three outs, the teams switch roles and the other team takes their turn at bat. The game ends when one team has scored more runs than the other team after nine innings.
