I mentioned in a previous post that I would come back to the subject. It’s such an odd term isn’t it? According to Wikipedia, that source of all knowledge in this Internet age, there are many theories but no real agreement about where the term came from. If you look at the Wikipedia entry for bullpen, you will find that much of the discussion centers on situations involving confinement.
Look at these pictures that I’ve taken in both major and minor-league parks, and I think you will agree that they all look like cages. Not surprisingly, though, Casey Stengel had a different idea. He said that the name came from the fact that relief pitchers spend their time shooting the bull, and thus the place they waited before coming into the game was the bullpen.
These are the home and visitors bullpens in Cincinnati. All rather cage-like, wouldn’t you agree?
