Shutout

In team sports, a shutout (a clean sheet (UK English) in association football) is a game in which one team prevents the other from scoring any points. While possible in most major sports, they are highly improbable in some sports, such as basketball.

Shutouts are usually seen as a result of effective defensive play even though a weak opposing offense may be as much to blame. Some sports credit individual players, particularly goalkeepers and starting pitchers, with shutouts and keep track of them as statistics; others do not.

Baseball

In Major League Baseball, a shutout (denoted statistically as ShO or SHO) refers to the act by which a single pitcher pitches a complete game and does not allow the opposing team to score a run. If two or more pitchers combine to complete this act, no pitcher will be awarded a shutout, although the team itself can be said to have "shut out" the opposing team. The only exception to this is when a pitcher enters a game before the opposing team scores a run or makes an out and then completes the game without allowing a run to score. That pitcher is then awarded a shutout, although not a complete game.
