Anything wrong?

[smbbcoach99]

At a game last night. NFHS rules. Score/inning irrelavent.
Runners on 2nd and 3rd, 1 out. Coach calls for intentional walk. Catcher steps to the right with both feet. He then puts arm out for the IW, pitcher throws it to him.

Batting coach begins to yell at top of his lungs, "BALK... That is a CATCHERS BALK. He is outside the catchers box and thats a balk!!!" Both umpires did their both to look at him, ignored him. He continued for the next 2 balls thrown. Coach then throws his arms up in the air, turns abruptly towards the outfield fence huffs (heard in stands) and that was the end of his show- went back to coaching his team.

I have looked through my books and can not see anything wring with this. Not have I found anything called a catchers balk.

Thanks for the help here.
