Here is the deal. We have played a whole season and now are down to our season finale. The other team has stacked all their girls infield the entire season (9 girls) and not assigned correct positions. My team has played the whole season with our girls in the correct positions. Is there a rule of how many girls can play infield or are they required to play the correct positions?
This is 7 year old Minor A girls. Any info would help. Game is 6 days away
