Working Behind Pitcher

[Stair-Climber]

10 and under girls fast-pitch and working by myself. Pitcher on one team throws very hard (around 60 mph), but has no control. Catcher cannot catch her and only stops about one out of every six or seven pitches. The pitches that get by her are all over the place. Many of these pitches are hitting my shin guards, plate shoes, mask, and whizzing by my head. In two innings, I get hit on the arms and thigh and it hurts. Two opponents are hit very hard with pitches and it was fortunate that more girls were not hit. Coach of the pitcher is stubborn or oblivious or something and won't take her out of game or tell her pitcher to slow the pitches down. It was a bad situation. If I was coach of other team, I would have refused to put my girls out there in that danger. Anyway, when this girl came out to pitch in the third inning, I decided to take my mask off and work the game from behind the pitcher. Anyone out there disagree with what I did? Also, in an ASA sanctioned game, do I have the authority to remove a bad and dangerous pitcher from that position in order to protect opponents?
