Inning - Division of play in sports such as baseball, softball, kickball, etc.

"An inning in baseball, softball, and similar games is the basic unit of play, consisting of two halves or frames, the "top" and the "bottom". In each half, one team bats until three outs are made, with the other team playing defense. A full baseball game typically is scheduled for nine innings, while softball games consist of seven innings; although this may be shortened due to weather or extended if the score is tied at the end of the scheduled innings. The use of the term inning in baseball and softball contrasts with cricket and rounders, in which the term is innings in both singular and plural. - Wikipedia"
