Yes, this is a balk. Pivot foot must be the foot touching the rubber. For a right-handed pitcher the pivot foot is the right foot!!

This is a trick I used to have my pitchers pull when the opposing team had a fast runner with a big lead-off at 2nd base. We picked off a few. Our right-handed pitcher would face 1st base and go to the set-position with his left-foot on the rubber, then he would throw straight back to second base. Umpires or the opposing team never noticed the deception. I'd call the play from the dugout, code word was "Convertible". It worked great and I never had a balk called. I had opposing pitchers after the game ask for me to teach them that great move. (I never did) One umpire at a tourney who umped 3 of our games finally noticed the deception, but he didn't know if it was a balk or not.

Just recently when taking my state high school umpire's test did I learn it was a balk!!
