Perfect game

A perfect game is officially called when one or more pitchers put out every batter on the offensive team over the course of the entire game. Perfect games that last nine innings are also referred to with the phrase “27 up, 27 down” – in other words, no player from the opposing team must reach a single base throughout all nine innings in order for the game to be classified as a perfect game. This includes the runner reaching base safely by any means, i.e. through hits, walks, third strikes that are uncaught, catcher’s interference or fielders, or fielding errors.

Do Fielders Contribute to Perfect Games?

The pitcher relies on the help of the rest of the defensive team to achieve a perfect game. The defensive team are responsible for putting out any hitters who manage to hit the ball, either by catching the ball on the fly or putting them out before they reach first base. While perfect games are not awarded to pitchers if the defensive team commit an error that enables a player on the opposing team to reach first base, this does not apply if the error takes place in foul territory.

What Else Does a Pitcher Achieve From a Perfect Game?

By the definition of a perfect game, a pitcher who achieves this status has also attained a no-hitter and a shutout by default.
