A "Complete Game" in baseball refers to a game in which a pitcher throws the entire game without being replaced by another pitcher. This means the same player is responsible for all nine innings, showcasing their endurance and skill. Complete games are relatively rare in modern baseball due to the increased use of specialized relief pitchers. Achieving a complete game is often seen as a significant accomplishment for a pitcher, as it demonstrates their ability to maintain performance throughout the game. Notable pitchers, such as Sandy Koufax and Nolan Ryan, are famous for their numerous complete games during their careers.
