Quick Summary

A closer is a specialized type of relief pitcher in baseball. This player's primary role is to enter the game in the late innings, typically when their team has a lead, and secure the remaining outs to "close" or win the game. Closers are crucial for preserving victories and are often brought in for high-pressure situations. A notable example of a successful closer is Mariano Rivera, widely regarded as one of the greatest relievers in baseball history.123
