Is the "intent" or "act" of hitting a batter the same as pitching inside, or establishing the inside part of the plate?
- pitching inside is not performed with the direct intent of hitting him (or at least at the amateur level it should not).
- you practice hitting inside spots during bullpens so as to be able to pitch inside, and establish that territory belonging to the pitcher
- you do not practice hitting a batter, and I am a firm believer that the brain maps what it practices. Remember last year A Rod was plunked by Dempster (I think it was him), however the first pitch missed as it sailed behind him. Why would a seasoned pro known for command, miss a large bodied professional like A Rod on his first attempt to hit him? Because it was not a pitch location that Dempster has mapped, and practiced.
I don't believe it is any opposing team's responsibility to take bad sportsmanship, and give the opponent any "teaching moment", nor do I think any perceived "teaching moment" will have any positive outcome, other than the the retaliating party feeling somehow avenged.
I like CoachB25's suggested method of handling it - coach to coach.
