Is this a balk?

[Mark T. DeNucci, Sr.]

NFHS Rules please (but I would also like NCAA and MLB/OBR rulings too).

F1 is a left-handed pitcher. R1 on first. F1, pitching from the stretch, goes to the set position. F1 lifts his not pivot first and starts to move it toward home plate; the non-pivot foot moves about twleve (12) inches toward home plate and then F1, without stopping his motion, steps with his pivot foot toward first base and throws to first base; if one where to draw the proverbial imaginary 45 degree line from the pitcher's plate, F1's non-pivot foot definitely lands on the first base side of the 45 degree line.

This happened in a H.S. game that was televised in the Toledo area and a balk was called by both the PU and the BU. I believe the call was correct because he started toward the plate with his non-pivot foot, but MTD, Jr. (young ones, they think they know it all, ; that is why I make him work the plate all of the time we umpire together, afterall he is only 19) believes it was not a balk because the non-pivot foot landed on the first base side of the 45 degree line.

Is this a balk?

I will hang up now and listen to your answers off the air. Thank you and good night. Let the fun begin.
