What is a Perfect Game in Baseball? 5 Facts to know

In baseball, a “perfect game” is a game in which no batter on either team gets to first base. The odds of this happening are very low, which makes it a truly amazing baseball accomplishment.

The pitchers for each team must go the whole game without giving up a hit, a walk, or a hit by pitch, and the fielders must catch every ball hit into fair territory without making a mistake.

Even though all eleven players on the field have to do their jobs perfectly, the pitcher is usually the one who gets the most attention for this.

Length Requirements

Different baseball leagues’ rules say that games must last longer than a certain number of innings to be considered “perfect.” Perfect games must go the full nine innings in Major League Baseball, which is the best professional league in the world.

Games that end before all nine innings have been played because of bad weather do not count. Games that last longer than nine innings are only perfect if neither team gets on base at the end.

There may not be a set number of innings for each game in leagues for younger players or those with shorter games (like seven or five innings).


Some people call a perfect game a “no-hitter” because neither team got a hit during the whole game. No-hitters are not always the best games, though, because batters can still get on base through walks or errors.

Even if the other team’s batters don’t get a hit or even reach base safely, they can’t score any runs, so a no-hitter can still be thrown and lead to a loss.

Common Components

For a pitcher to throw a perfect game, there can’t be any walks or hits, and there can’t be any hits, either. In the same way, the pitcher needs to have great defense.

In addition to the fielders not making any mistakes, many perfect games have a defensive play in which a fielder turns a near-hit into an out with a diving catch, a long throw, or some other great play.

Because poorly hit balls often drop or roll where fielders can’t get to them in time to make an out, many people think that luck also plays a role.

Major League History

As of the 2012 MLB season, 23 perfect games have been played. The most ever in a single season was three of them, which happened in 2012. Each of these perfect games was thrown by the same pitcher the whole time, not by a pitcher who took over for the original starter.

On October 8, 1956, Don Larsen of the New York Yankees did it against the Brooklyn Dodgers in Game 5 of the World Series. No pitcher in the major leagues has ever thrown two perfect games.


Since the 1980s, there have been more perfect games in the MLB, but they still don’t happen very often. Larsen had to wait 34 years to throw a perfect game. He was only the sixth pitcher since 1880 to do so.

Only three more happened in the next 24 years, bringing the total to nine in 101 years. But between 1981 and 2012, there were 14 perfect games: three in the 1980s, four in the 1990s, one in 2004, one in 2009, two in 2010, and three in 2012.
