Wow....this makes me feel a lot better about the level of play around here. Even most of our middle school games are better than some of those described.
Heck, you'll have games where 1/2-3/4 of the kids on both sides have travel team batting helmets, bat bags, etc. Had one of those, and it was 1-0, great pitching, both teams infielders made spectacular plays, and we were out of there in an hour...for 7 full.
Had a JV last year where the coach had had food poisoning from the night before, and she only had 8 to start. The other team took it easy on them; they would score 5 in an inning, then ease up (lefties batting right, etc), or the coach would have base runners step off early to get an out, and so on. They got their 15 run lead in the 5th, got the other team out, and we went home. I always consider when a coach does that as an act of sportsmanship.
