When did they change the balk rule?

[Durham]

A small rule of thumb; usually if saying it makes me feel good, I probably shouldn't say it.

Example,

Coach comes out on a close one and says, " you missed that!" I reply, your team has 4 erros in 3 innings and I didn't see you run out here to tell them that they missed those." Sarcasim is usually bad on the field, but that doesn't mean I sometimes don't use it.
