In cricket, the batting order is the sequence in which batters play through their team's innings, there always being two batters taking part at any one time. All eleven players in a team are required to bat if the innings is completed (i.e., if the innings does not close early due to a declaration or other factor).
The batting order is colloquially subdivided into:
The order in which the eleven players will bat is usually established before the start of a cricket match, but may be altered during play. The decision is based on factors such as each player's specialities; the position each batter is most comfortable with; each player's skills and attributes as a batter; possible combinations with other batters; and the match situation whereby, for example, the team may require a more defensive or attacking player at that point in the innings. Also, a middle order batter in Tests may open for ODIs and Twenty20 due to their aggressive approach to the game.
