I'm relatively new to girl pitch softball (DD in 8U), but could someone please educate me on why I see so many girls at all levels continually make illegal pitches (i.e. right foot comes up in the air off of the pitcher plate before girl releases the ball, hopping, etc.). It's my understanding that the "drive foot" has to start on the plate and can only move along the ground. Maybe some softball santioning bodies allow this? Thanks.
