Pitching A No-hitter
A no-hitter is a game in which one of the teams prevented the other from getting a hit. Throwing a no-hitter is rare and considered an extraordinary accomplishment for a pitcher or pitching staff. In most cases in the professional game, no-hitters are accomplished by a single pitcher who throws a complete game. A pitcher who throws a no-hitter could still allow runners to reach base safely, by way of walks, errors, hit batsmen, or batter reaching base due to interference or obstruction. If the pitcher allows no runners to reach base, the no-hitter is a perfect game.
