coach- I would add a #4 also. There are many times where a pitcher may feel as if they are a bit overwhelmed throughout the game. The mound can be a VERY lonely place when things aren't going your way, and the loneliness can seem like it lasts for days. Often times a pitcher can be so wrapped up in the situation around them or the emotions that they feel because of the happenings of the game that they lose their mental composure. Mental composure can be a difficult read for a coach or a catcher because it is sometimes difficult to see a pitcher losing it (the "poker face" remains on). I feel that during times of the game that might seem a bit overwhelming for a pitcher, or a time of a game where the momentum seems to be turning for the other team's benefit, it could behoove the catcher to take a mound visit. Talk about the weather, a teacher, a girlfriend, how stupid an opponent's socks look. Anything that could be construed as a normal conversation that could take the pitcher out of the element of feeling overwhelmed and back into the feeling that he is accustomed to.
