Let’s start with a tip of my hat to DBacksEurope, who wrote The Reliable Reliever. He applied process control charts to distinguish between reliable relievers and unreliable relievers. It inspired me to explain my ways to determine reliable relievers; there are two methods. One is ‘got the job done,’ and the other is ‘broken goose eggs.’ The goose egg method was developed by Nate Silver and he explained it here.

Got the job done. This method ignores the game situation when the reliever entered the game.
