What Does a No-Hitter Mean in Baseball?

In baseball, a no-hitter means a game in which one pitcher pitches the entire game (9 innings in Major League Baseball) while not giving up a single hit to the opposing team.

This is usually a credit to a pitcher who is locked in, has his stuff working, and shuts down an opposing team’s hitters. It’s a special feat—very difficult to achieve and widely celebrated in baseball circles.

While a less glamorous but still effective way to achieve a no-hitter is with a group of pitchers—a starter and one or more relievers—for this article we’ll focus on an individual no-hitter.

What’s the Difference between a No-Hitter and a Perfect Game in Baseball?

In a no-hitter, a pitcher does not give up any hits to the opposing team. However, he may give up walks, hit a batter with a pitch, or a runner may reach on a fielding error.

In a perfect game, a pitcher does not allow any baserunners, whether by hit, walk, or fielder error*.

*The one exception is if the error occurs in foul ground, in which case a runner is not allowed a base, so the perfect game is still intact.
