In cricket, an extra (sometimes called a sundry) is a run scored by, or awarded to, a batting team which is not credited to any individual batter. They are the runs scored by methods other than striking the ball with the bat.
The extras are tallied separately on the scorecard and count only towards the team's score. Giving away many extras is often considered as untidy bowling.
There are five types of extra: no-ball (nb), wide (w[1] or wd), bye (b), leg bye (lb), and penalty run (pen[2]).
