Interesting how? Since I generally sit on a bucket in (or near) the dugout doorway, I talk to our in-the-hole batters pretty frequently. In this particular instance, the conversation was more about pitching than hitting.
I would think you would want your players, especially one who should be well into the mental process of her upcoming at bat to be fully engaged in the task at hand. Not having a philosophical discussion. Don't get me wrong, it was a fine conversation to have with her, just a very unusual time and place. If she was in the hole and talking to a teammate about going shopping for shoes after the game how would you have reacted?
