bringing in outside help is a sore subject...you end up sitting your own players (if they are struggling) or feeling obligated to use a guest player (is it fair for their parents to have them change their plans and then NOT play them?)....maybe it was a roster move due to injuries (or graduations/other commitments/etc) or it was completely selfish, who knows...
in the end, by the time 16's roll around, it's all about winning...as for the pitcher/player who was sat down, I'm sure it's not ever easy to sit...i even tell my DD..."hit 400 and coach is forced to play you, hit 200 and it makes his job easier"
as for the struggling players confidence, well, that's the subject of another post somewhere in OFC land :-X
