Balk Question?

[sprivitor]

Hi All, newbie to this particular forum and have a question regarding a Balk.

Forgive me if this posts twice.

Using NFHS rules.

RHP, R1. F1 moves pivot foot off rubber towards third then steps towards 1st base with his left foot when throwing the ball to attempt a pick off of R1. This should not be called a balk, correct?

Now, same situation above, but F1 raises his left heal while still maintaining contact with the balls of his feet to the dirt, he then pivots and throws as above to 1st base. Would the raising of his left heal be considered a balk?

Thanks for any answers!
