Pitcher's arm back limit ??

don't have my rules with me here, but i believe the rule states 'not more than one revolution' and at the same time says the pitcher can 'drop her arm to the side or back' as part of the delivery

if her arm goes back, that's automatically more than one revolution ... isn't it ... ???

Speaking ASA, the rule (6-3D) says the pitcher must not make 2 full revolutions. Therefore, the backswing can go as far back as she wishes, so long as once the forward delivery starts, she does not make 2 complete revolutions. I've seen a pitcher who's backswing was almost vertical.
