Coaching the coach...

[Andy]

Yesterday - Jr college game, NCAA rules, bases loaded, no outs.
I am BU. Long fly ball hit to F8, I come into the infield to pick up the tag ups at first and second, my back is to third base.

The ball is caught, both of my runners hold their bases.

The defensive coach comes out of her dugout toward me yelling that "she left early, oh my god, how could you not see that, what were you looking at?!" My first thought was....what the h*ll is she talking about?????

The coach turns toward my partner at the plate and states her concern again that the runner on third left early....my partner tells her that the runner on third is not my (BU) call...you need to appeal. Finally, we get a proper appeal and my partner declares the runner out for leaving early.

I started thinking how I would have interacted with the coach had she kept coming out to me.....Should I have just told her that the runner on third is not my responsibility and she needs to talk to my partner? I'm also interested to hear if any of you here would tell her she needs to make a proper appeal? I don't think I would have...she should certainly know this basic procedure.

Opinions??????
