Couldn't some of the referenced individuals be consolidated into "Cheerleader" - The "Great Hit Guy" who says great hit as the player heads to the dugout after making an out, the "Good Eye, Way to Watch" guy, the "It's Not Your Fault Mom?" Added into that category is the team supporter (not necessarily a parent) who stands behind home plate and encourages the pitcher after each pitch he throws - "good pitch," "just a littler higher," "bring it in a little," "nice drop," etc. Or the sister of "It's Not Your Fault Mom" - "just a loud noisy strike" to the pitcher (when the ball goes over the fence barely foul), "you'll get 'em next time" (when the player strikes out for his third time of the day), "you can do it with two" (when the player has an 0-2 count on him), etc. All of these folks are The Cheerleader.
