Baseball’s unwritten rules [Globe]

They’re guidelines, really. Nothing’s official, but the players know to follow them. Or else … watch out! What I love most is these are really put on display during a rivalry, like the one we’ll all be watching this weekend when the Yankees come to my town (at least for the next few weeks). Other times you’ll see them come to light during a no-hit bid, or a dirty play. 

I put together this list of baseball’s unwritten rules for Boston.com, but it may very well foreshadow the Sox-Yanks series. Enjoy.
