In baseball, the term 60 6 refers to a statistical achievement known as a complete game. A complete game happens when a pitcher is able to pitch for the entire duration of the game without any assistance from their team's bullpen or relief pitchers. The number '60' refers to the number of outs (three outs per inning, and nine innings in a regulation game), and the number '6' signifies that the pitcher threw all nine innings. This means that the pitcher was able to retire all 27 opposing batters by themselves. For instance, if a pitcher starts the game and continues pitching until the end without being substituted, they are said to have pitched a complete game. This accomplishment showcases the pitcher's ability to stay strong and effective throughout the entire game, not requiring any assistance from other pitchers on their team. Complete games were more common in the early days of baseball when pitchers would throw for the whole game on a regular basis. However, in modern baseball, complete games have become rarer due to strategies that involve utilizing multiple pitchers to maintain a team's performance and reduce the risk of injuries. So, when someone says 60 6 in baseball, they are referring to a remarkable feat by a pitcher who was able to dominate the game from start to finish.
