Why there is night watchman in cricket?
A “Night Watchman” is expendable as a batsman. In a manner of speaking he is called upon to the altar with the willingness to sacrifice his own wicket in order to protect that of a more distinguished batsman whose wicket is far more valuable to the team. Such a situation typically arises when 1 ) a new batsman is slated to walk out in the middle with so little time remaining for close of play that it is not worthwhile for him to do so. 2 ) a new batsman is slated to walk out in the middle with playing conditions very unfavourable for batting with the close of play just a liitle away.
