In Major League Baseball (MLB) history, there have been only 24 perfect games pitched. A perfect game is one in which a pitcher faces the minimum of 27 opposing batters across nine innings without allowing anyone on base. It is a subset of the more common no-hitter (more than 300 recorded in MLB history), in which a pitcher (or multiple pitchers) prevents opponents from recording a hit throughout a game but allows at least one opponent on base, be it via a fielding error, a base on balls, or another way.
The team with the most perfect games pitched for them is the New York Yankees, who have had four players do so, including Don Larsen, who, in 1956, famously pitched the first perfect game in the World Series. The Los Angeles Dodgers and the Tampa Bay Rays have each had perfect games thrown against them an all-time high of three times. The Seattle Mariners are the only team to have a player pitch a perfect game for them and another throw one against them in the same season, which occurred in 2012, a season that saw a record three perfect games hurled across the major leagues. Although a number of the sport’s greatest players have pitched a perfect game, the difficult and idiosyncratic nature of the accomplishment means that it has been done by All-Stars as well as career journeymen pitchers. Below is a list of every major leaguer who has achieved this historic feat.
