A cricket umpire is an official who oversees a cricket match, ensuring that the game is played according to the rules. They make decisions on various aspects of the game, such as whether a batsman is out or if a ball is a no-ball. Umpires are crucial for maintaining fair play and the integrity of the match. There are usually two on-field umpires during a game, along with a third umpire who can review certain decisions using video technology. Umpires must have a deep understanding of the Laws of Cricket and possess strong communication skills to manage players and maintain order on the field.
