Innings is a term referred to a team"s turn of batting. In other words,it is the time during which a team goes out in the middle to bat.
The game of cricket has 11 players to a side and all eleven are eligible to bat, two at a time. When one batsman gets out he is replaced by another. However, due to the playing condition, which requires two batsmen at the crease in order for the game to go on, one batsman remains not out at the end of the innings (batting duration). In other words, when the opposition has dismissed ten out of the eleven batsmen the innings of the team comes to a close.
In Test cricket each team is eligible to bat twice – that is they aregiven two innings each, whereas in One-day International cricket, theteams gets only one innings each of limited overs (normally 50).
Note: The fielding side gets to field all its eleven players.
