Balk or No Balk

"The question I have is whether he turns his shoulders?"

I don't see any significant shoulder movement. However, the shoulder does have to (physically) move in the direction of 1st when he first STEPS to throw there.

If the shoulders were to move slightly toward third (after he came to the Set), that would be an indication of a pitch and he would be committed to follow through with a pitch. Any throw to 1st then would be a balk.

Also, he can move his head to check the runners as much as he wants after he comes to the Set (as long as he doesn't significantly move those shoulders). Any twitch of the shoulders could be viewed as feint.
