Legal Feint to first?

[jdmara]

I struggled with this last night and I'm still not sure if it's legal or not.

NFHS rules. R1. RHP. The pitcher would step backwards off the pitcher's plate with his pivot foot, his non-pivot foot would stay stationary, and he would turn his shoulders towards 1B. Sometimes his shoulders would turn after his foot landed behind the pitcher's plate and sometimes it would be nearly one motion.

Obviously by turning his shoulders after his pivot foot landed (behind the pitcher's plate) this would be a legal move. But is merely turning of the shoulders considered a feint (in other words, is this move illegal if he turns his shoulders before his pivot foot lands)?

Thanks
