You spikes high you try to roll up an ankle or be a general butthead earns you #1. Let me be clear drilling is only meant for the ribs never the head. It builds team chemistry when a pitcher knows his teammates will support him in doling out how the game should be played. I've seen it taught and yes as an umpire I've issued warning afterwards. Have I ever run a pitcher after drilling? Yes but normally that's from the fight afterwards. Showing up your opponent or disrespecting the game generally results in a drilling and after a couple of them players self evaluate "why am I being plunked." And they calm down.
