Baseball is a game of unwritten rules. Don’t steal bases when you have a big lead. Don’t bunt to break up a no-hitter. Retaliate when one of your teammates is hit by a pitch. It is understood that once you get to The Show, you abide by these rules. There is no need to speak of them to the media, to your teammates, or to anyone else, for that matter. This is what made Cole Hamels’ recent admission to intentionally plunking rookie phenom Bryce Harper all the more alarming.
