Origin? Is this real? Edit

I have never heard the term used in the context of baseball, except on Deep Space 9. Is there any story behind it being used in the episode?96.238.211.171 10:41, April 16, 2013 (UTC)

According to a baseball dictionary it's a historical term. --(boxed) (talk) 01:32, April 17, 2013 (UTC)
