A team screamed at my DD while her arm was coming down the path to release. It startled her and she released the pitch into the ribcage of the batter. It made a real deep sounding thud. That was the last time they did it. Our coach admonished them for getting their own player hurt. We've also had the same team call our girls names and refuse to shake hands after we beat them. Horrible sportsmanship and not what sports is about.
