how many perfect games in mlb

There have been 24 perfect games pitched in Major League Baseball (MLB) history. A perfect game is one in which a pitcher faces the minimum 27 batters across nine innings without allowing anyone to reach base by any means—no hits, walks, errors, or other ways to get on base. The most recent perfect game was thrown by Domingo Germán of the New York Yankees on June 28, 2023, against the Oakland Athletics. Among the 24 perfect games, 22 have occurred since the modern era began in 1901. Notably, no pitcher has thrown more than one perfect game in MLB history. This is a rare and exceptional feat, with only 0.01% of MLB games resulting in a perfect game across more than 237,000 games played.
