I enjoyed Zap's comment that throwing at batters even happens in 12u girls softball. This happened to my daughter when she was playing in an 18u national tournament. From the distance they pitch, some girls are throwing the equivalent of 90+ fastballs in terms of reaction time. My daughter had 2 triples and a double off the pitcher. She comes up the 4th time and promptly drills the first pitch down the right field line but foul. Coach on other team steps out of dugout, yells at his pitcher "I told you to take care of this", crosses both arms across his chest and then slashes his throat. My daughter is a slap hitter. For those unfamiliar with girls softball, that means they are in motion toward the pitcher as they are swinging. With the next pitch, the pitcher drills my daughter right in the face mask of her helmet. It was clear to everyone what just happened. Thankfully they are required to wear cages on the front of their helmets. My daughter was pissed and slammed the bat down. Umpire takes his mask off, lectures her and throws her out of game for throwing bat down. Our side was livid and two more coaches got tossed. The end result for the other team's coach was that he not only hit the batter, but got her tossed from the game so she couldn't hit again. Throwing at batters isn't unique to MLB.
