D. don't hit a home run when your team is leading the game I have played baseball and there is clearly no etiquette against this. First, home runs aren't exactly controllable as they are often the result of hitting a bad pitch with the right loft. These often result in fly ball outs if they don't make it far enough. Second, your team may lead by only a little bit and want to extend their lead as much as possible. If you watch any amount of baseball you will see that there is clearly no rule against hitting a home run at any point.
