Pitching clarification

[aschramm]

I'll preface this post by saying that probably my hardest rule to grasp right now deals with balks pitching regulations.

I've had alot of situations this year, where say R1 is leading off and the right-handed pitcher is working from the set position. The pitcher lifts and steps towards third with his pivot foot, then steps toward first with his non-pivot foot and throws the ball to check the runner. I would think this move would be considered the 'jump turn' that is mentioned in 6-1-3 (FED rules).

Is this move completely legal?
