Illegal pitch?

[RKBUmp]

Worked an entry leval tournament this weekend, 10's, 12's, and a few 14's generally C level teams, a few B level at best. Had a 12 pitcher this weekend do something I have never seen before. About 30% of the time she would step onto the pitching plate, turn her feet about 45 degrees to the pitching plate and then rotate her hips and shoulders to about in line with the SS and 1/2 way between home and 1st base. The rule states the shoulders must be in line with 1st and 3rd base, but how much if any do we allow the shoulders to be turned? And if it is illegal, is it the plate umpires or base umpires call? Its visible from the plate, but certainly much more pronounced from the field.

Talked to several of the other umpires at the complex and got mixed reviews. Some felt that as long as when she initially stepped on her shoulders were in line she was fine, others agreed it was probably illegal.
