DTQ:

First, watch the Jim Evans balk video multiple times. It is very good and it talks about the very obvious balks as well as the more subtle ones.

My question to you is, why do you state you have difficulty called balks while on the bases? Do you not have the same difficulty working the plate? I need to know what you mean by the distinction.

In the meantime, I would recommend you learn and call the real obvious balks as you gain more experience and work more big field ball. So, here are the big 5 for me:

1) Not coming to a complete stop prior to delivering to the plate.
2) Faking to first while on the rubber.
3) Stopping the delivery during a pitch.
4) Not stepping toward the base being thrown to.
5) Disengaging the rubber incorrectly.

There are a lot more than this, but I feel if you start with these you will get most balks that are committed.
