Ditto to all of the previous comments (including the 3-ring nature of JV games!) But let me repeat part so that hopefully some people who read this will take note:
1. There is no requirement of "announcing" substitutes, to the official scorekeeper or anyone else. It's a good thing, customarily done, it may be covered between the ump and coaches pregame, but if a sub isn't announced, there's no penalty (as long as he's a legal sub under the rules which cover that.)
2. Scorekeepers have no business butting into the game. If the ump has the count wrong, unless he asks you, keep quiet. If someone does bat out of order, or is subbed illegally, unless the ump asks you, keep quiet. Two (or four) outs in the inning? See above.
