Balk calls in College Super Regional

[ibcallindux]

I can't remember what game this was in but a balk was called when the pitcher did not come to a complete stop before delivering the pitch from the stretch. The color man, Kyle Petersen, said that in the college game the pitcher has to come to a complete stop. He went on to say that in the majors that was not the case. Did I hear that right or did I misunderstand him? Anybody else pick up on that?
