A "Perfect Game" in baseball is a rare achievement where a pitcher faces and retires every batter in a game without allowing any hits, walks, or errors. This means that no opposing player reaches base, making it one of the most difficult feats in the sport. Only a few pitchers in the history of Major League Baseball, such as Sandy Koufax and Felix Hernandez, have accomplished this. In a Perfect Game, the pitcher must maintain exceptional control and skill throughout the entire game, typically lasting nine innings. The achievement is celebrated as a pinnacle of pitching excellence, highlighting the pitcher's dominance over the opposing team.
