No, that headline isn't a joke. I came across a piece this evening that was published on Friday. Apparently, Derek Holland went into detail on what the pitchers do in the bullpen to stay entertained. It would seem we may have found a possible cause for all of the pitching injuries. Don't take my word for it, I'll just post up the link here.
Just don't say I didn't warn you, and if you'd rather not know what Fart Bottle Roulette is, then perhaps you'd be better off pretending you never saw this post.
