Unwritten rules stink.
Most baseball fans are well aware of this fact, and the sport is full of them.
You’re not supposed to steal bases when your team has a big lead. You don’t use your closer in a tie game on the road. You don’t stand at the plate and admire a long home run. You don’t flip your bat in the air after said dinger, you don’t talk publicly about a no-hitter in progress, and you don’t bunt in order to try and break up a no-no.
