Pitching rules 10U asa
I am coaching my daughters team and we don't have any pitchers. My daughter looks ok when throwing, but has about a 10% chance of throwing a strike. We walked 21 of 21 hitters in our first game. After reading the Asa rules, I didn't see anything about the pitcher being required to make a full revolution with the arm. I asked a girl that pitched in college, and she told me that they were not required to make a full revolution although it is rarely taught that way because it is ineffective at higher levels. I worked with my daughter at pitching with a half arm swing like a coach would pitch. She has about a 50% chance of throwing strikes. However, when we went to play today, the umpire wouldn't let her pitch like that. We had about a 2 minute discussion and I eventually gave in and she threw the other way, with a full revolution. She walked 16 of 18 today (improvement!!). I will continue to work with her and the full arm revolution, but can anyone tell me if I was wrong in my interpretation of the rules?
